A line passes through the point. (4, -7) and has a slope of 5/2
Write an equation in slope-intercept form for this line.
t p = through point
s = slope
[tex]y - y(t \: p) = (s) \times ( \: x - x(t \: p) \: ) \\ [/tex]
[tex]y - ( - 7) = \frac{5}{2} \times (x - 4) \\ [/tex]
[tex]y + 7 = \frac{5}{2} \times (x - 4) \\ [/tex]
[tex]y + 7 = \frac{5}{2}x - \frac{5 \times 4}{2} \\ [/tex]
[tex]y +7 = \frac{5}{2}x - \frac{20}{2} \\ [/tex]
Subtract both sides -7
[tex]y = \frac{5}{2}x - 10 - 7 \\ [/tex]
[tex]y = \frac{5}{2}x - 17 \\ [/tex]

The equation in slope-intercept form is y= 5/2x - 17.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Slope = 5/2
and, point (4, -7).
Using Slope- intercept form
y = mx + b
y= 5/2x + b
As, the line passes through (4, -7)
-7 = 5/2(4) + b
-7 = 5(2) + b
-7 = 10 + b
b= -17
So, the Equation of line is y= 5/2x - 17.

A coin is tossed and -sided die numbered 1 through is rolled. Find the probability of tossing a and then rolling a number greater than .
Complete question :
A coin is tossed and a die is rolled. Find the probability of tossing a tail and then rolling a number greater than 2.
Answer : 1/3
Step-by-step explanation:
For a coin :
Sample space = (T, H)
Probability = required outcome / Total possible outcomes
Probability of tail, p(T) = 1 / 2 = 0.5
For a fair die:
Sample space = (1, 2, 3, 4, 5, 6)
Required outcome = number greater than 2 = (3, 4, 5, 6) = 4
P(number greater than 2) = 4/6 = 2/ 3
Hence, probability of a tail, then a number greater than 2 :
(1/2 * 2/3) = 2 /6 = 1/3
the other one is 27
Answer:
the scale factor is 9 and x = 58.5
Step-by-step explanation:
to get the scale factor just do DE/AB so 27/3

If m<7 is 2x + 30 and m<28 is 3x - 10, find the
following:
Answer:
x = 32
m∠7 = 94
m∠8 = 86
m∠3 = 94
Step-by-step explanation:
(2x + 30) + (3x - 10) = 180
5x + 20 = 180
5x = 160
x = 32
m∠7 = 2(32) + 30 = 94
m∠8 = 3(32) - 10 = 86
or
m∠8 = 180 - 94 = 86
m∠3 ≈ m∠7 (corresponding angles)

Answer:
2 19/21, 61/21
Step-by-step explanation:
First, lets make the denimonators, "3 and 7" common. 3 and 7 are prime numbers, so the common denonminator is "21".
For 7/3, multiply by "7/7" and for 4/7 multiply by "3/3".
49/21 + 12/21
Add.
61/21
61 is a prime number so this answer will be your final answer.
(unless you have to put it as a mixed number which would be 2 19/21)
Answer:
61/21
Step-by-step explanation:
The 2 fractions must have a common denominator and you do that by finding the LCM and the multiply the numerators by what you multiplied the denominators by in order to get that number. From here you must add the numerators together and keep the denominator the same and then you get that answer. You cannot simplify anymore so your answer is above.

In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume that passengers average 192 pounds in the summer, including clothing and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 31 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 21 passengers. What is the approximate probability that the total weight of the passengers exceeds 4432 pounds
Answer:
The approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709
Step-by-step explanation:
[tex]\mu = 192[/tex]
[tex]\sigma = 31[/tex]
No. of passengers = n = 21
We are supposed to find the approximate probability that the total weight of the passengers exceeds 4432 pounds
[tex]x = \frac{4432}{21} \sim 211[/tex]
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{211-192}{31}[/tex]
Z=0.612
refer z table
P(Z<211)=0.7291
P(Z>211)=P(Z>4432)=1-0.7291=0.2709
Hence the approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709

100 points please help ! What is the name of the line of reflection for the pair of figures
Answer:
Hey!
I think the line must be LINE R
Step-by-step explanation:
As you can see it must be the Line of Reflection for both figures because it is EQUIDISTANT (equal distance from the 2 shapes). It runs PARALLEL in angle to the shapes too...
It can't be Line P because the line does not produce equal shapes on either side of it...
It can't be Line Q because it only provides the reflection result on one of the shapes, not BOTH...
So your answer is Line R

Consider the following.
P = −0.1s3 + 6s2 + 400.
Required:
a. Find the amount s of advertising (in thousands of dollars) that maximizes the profit P (in thousands of dollars).
b. Find the point of diminishing returns.
Answer:
A) s = $40 (in thousands of dollars)
B) point of diminishing returns is at;
(20, 2000) in thousands of dollars
Step-by-step explanation:
We are given the profit function as;
P = −0.1s³ + 6s² + 400
A) To maximize the profit, we need to find the first derivative and equate it to zero.
Thus;
dP/ds = -0.3s² + 12s
At dP/ds = 0, we have;
-0.3s² + 12s = 0
0.3s² = 12s
0.3s = 12
s = 12/0.3
s = $40 (in thousands of dollars)
B) To find the point of diminishing returns, we need to find the 2nd derivative of the given profit function and equate to zero.
Thus;
d²P/ds² = -0.6s + 12
At d²P/ds² = 0, we have;
-0.6s + 12 = 0
0.6s = 12
s = 12/0.6
s = 20
At s = 20,
P = −0.1(20)³ + 6(20)² + 400
P = -800 + 2400 + 400
P = 2000
Thus; point of diminishing returns is at;
(20, 2000) in thousands of dollars
Tracy wants to buy some pies for her sisters and she has a budge
apple pies, $4.5 banana pies, and $5.5 chocolate pies. She wants
sisters and must buy as many chocolate pies as apple pies and ba
How many of each item should she buy? Write a system of equati
this problem.
# of applie pies =
# of banana pies =
# of chocolate pilis
Answer:
Tracy must buy 4 apple pies, 4 banana pies, and 8 chocolate pies.
Step-by-step explanation:
The complete question would be:
"Tracy wants to buy some pies for her sisters and she has a budget of $82 to spend on $5 apple pies, $4.5 banana pies, and $5.5 chocolate pies. She wants 16 pies for her sisters and must buy as many chocolate pies as apple pies and banana pies combined. How many of each item should she buy?
Write a system of equations of this problem."
Then, we will write a system of equations according to the information given in the problem:
We must consider each type of pie as an unknown, so:
x: the amount of apple pies
y: the amount of banana pies
z: the amount of chocolate pies
As she has a budget of $82, the amount of each pie must be multiplied by its price and the total sum must be 82:
5x + 4.5y + 5.5z =82 (1)
The total amount of pies must be 16:
x + y + z = 16 (2)
And the amount of chocolate pies must be equal to the quantity of apple pies and banana pies combined:
z= x + y (3)
System of equations:
(1) 5x + 4.5y + 5.5z =82
(2) x + y + z = 16
(3) z= x + y
First, we subtract x and y on 3 on both sides:
z - (x + y )= x + y - (x + y)
-x -y +z = 0
Then, we add 2 and 3:
(2) x + y + z = 16
(3) -x -y +z = 0
2 z=16
z=8
We replace the value of z on 3 and substract x on both sides:
x + y =8
y=8 - x
We use this on equation 1:
5x + 4.5y + 5.5z =82
5x + 4.5×(8-x) + 5.5×8=82
5x + 36 - 4.5x + 44 = 82
0.5x + 80 =82
0.5x=82-80
0.5x=2
x=2/0.5
x=4
We replace the values of x and z on equation 2:
x + y + z = 16
4 + y + 8 = 16
y + 12 = 16
y=16-12
y= 4
Tracy must buy 4 apple pies, 4 banana pies, and 8 chocolate pies.

Based on the ratio shown in the double number line, what is the cost for 1 pound of avocados?
S
Answer:
$1.8
Step-by-step explanation:
Given :
5 pounds of avocado = $9
This means that 5 pounds of avocado cost $9; The cost of 1 pound of Avocado can be obtained thus ;
Let cost of 1 pound of avocado = a
5 pounds = $9
1 pound = a
Cross multiply
5 * a = $9 * 1
5a = 9
Divide both sides by 5
5a / 5 = 9/5
a = 1.8
Hence, 1 pound of avocado will cost $1.8

Answer:
The amount of time that Sarah sleeps is 6<x<8
Step-by-step explanation:
Mathematical inequality is that proposition that relates two algebraic expressions whose values are different. It is a proposition of relation between two different elements, either by greater, lesser, greater or equal inequality, or less or equal.
A compound inequality (or combined inequality) is two or more inequalities joined with or and and.
When two inequalities are joined with and, they are often written as a double inequality.
You know that teenagers should sleep between 8 and 10 hours per night.. Being x the number of hours slept per night, this can be represented by the following double inequality:
8<x<10
If Sarah normally sleeps 2 hours less per night, this indicates that she sleeps between (8-2) and (10-2) hours per night, that is, between 6 and 8 hours. Represented by a double inequality, Sarah normally sleeps:
6<x<8
The amount of time that Sarah sleeps is 6<x<8
