Answer:
-3/2,collinear.
Step-by-step explanation:
slope of PQ=(0-3)/(2-0)=-3/2
eq. of line PQ is
y-3=-3/2(x-0)
y-3=-3/2 x
or2y-6=-3x
or 3x+2y=6
if R(4,-3) lies on it,then
3(4)+2(-3)=6
12-6=6
or 6=6
which is true.
Hence points P,Q,R are collinear.
and line has aslope=-3/2
Answer:
-3/2

A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?
Answer:
The Axis of symmetry shows the highest point on the line and is a vertical line at the highest point on the graph x=1.5, y=36
Step-by-step explanation:
checked on a graphing calculator
Answer:
t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.

Gary can ride his bike 6 miles in 20 minutes. At this rate, how many miles can he ride in 100 minutes?
Answer:
30 miles
Step-by-step explanation:
We can use a ratio to solve
6 miles x miles
------------ = -------------
20 minutes 100 minutes
Using cross products
6 * 100 = 20 x
Divide each side by 20
600/20 = 20x/20
30 =x
Answer:
30 miles
Step-by-step explanation:
First you want to divide 100mins by 20mins which will equal 5
Then multiply 5 by 6 which will equal 30
1. A line passes through (9, -9) and (10,-5).
a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.
Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45

Which equation has no solution?
A. |-x – 31 = 5
B. 2x – 11 = 0
C. 15 – 3x = -8
D. |-x + 91 = 0
Answer:
D
Step-by-step explanation:
There is no equation which have no solution.
What linear equation has no solution?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
1. 1/(x - 31) = 5
1 = 5 · (x - 31)
1 = 5 · x - 155
5 · x = 156
x = 31.2
2. 12 · x - 11 = 0
12 · x = 11
x = 11/12
3. 15 - 3 · x = - 8
3 · x = 23
x = 23/3
4. - x + 91 = 0
x = 91

Answer:
3) The function's leading coefficient is negative.
Explanation:
(1) Is not the answer because when x = 3, f(x) = 0.
(2) Is not the answer because when f(x) = -3,
x = 0.
(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.
Therefore,
(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.

For what number of songs will the monthly charge be the same?
Answer:
50 songs at $35
Step-by-step explanation:
Answer:
x = 50, y = 35
Step-by-step explanation:
Solve this system of linear equations by using substitution. Equate the two equations to one another, thus eliminating y:
0.4x + 15 = 0.2x + 25
subtract 0.2x from both sides, obtaining: 0.2x + 15 = 25, or, after combining the constants, 0.2x = 10.
Finally we divide both sides by 0.2, which results in x = 50.
Use the first equation to find y: y = 0.4(50) + 15 = 20 + 15 = 35

A= P(1+ r over n)^nt
Answer: 12.6 years
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r/n) nt
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Nominal Interest Rate (decimal form, 4/100= 0.04)
n= number of compounding periods in each year (1)
t = years
Replacing with the values given
8200= 5000(1+ 0.04/1)^1(t)
Solving for t
8200 =5000 (1.04)^t
8200/5000 =(1.04)^t
1.64 =(1.04)^t
log 1.64 =log (1.04)^t
log 1.64 = t log (1.04)
log 1.64/ log (1.04) =t
t = 12.6 years

Answer:
8.106
Step-by-step explanation:
Use Pythagorean Theorum for this question, a^2+b^2=c^2
If you put the numbers into the equation you get 6.3^2+5.1^2=c^2.
Simplify and get 65.7=c^2
To get rid of the square, you square root both sides, which will get you 8.106=c (since the answer wants round to 3 numbers behind the decimal point)
Therefore the missing length is 8.106cm. (For estimation just write a random number you think it would be before actually solving the problem.

Answer:
Step-by-step explanation:
(x +13) + (4x + 2 ) = 180
5x + 15 = 180
Subtract 15 from both sides
5x = 180 - 15
5x = 165
Divide both sides by 5
x = 165/5
x = 33
Check
x + 13 = 33 +13 = 46
And
4x + 2 = 4*33 + 2 = 132 + 2 = 134

9x - 4y = 3
if we double the first equation and add up to second one, we cancel 4y:
12x+9x=60+3 ⇒ 21x=63 ⇒ x=3now we can find y:

Answer:
Given below
Step-by-step explanation:
M is Mikey and B is Betty in,
Current ages:
M= x
B= 3x (cuz she is 3 times older)
After 5 years
M= x+5
B= 3x+5 (5 years added to present age)
It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))
So,
3x+5 = 2(x+5)
3x+5 = 2x+10
3x -2x = 10-5
x = 5
Therefore,
The current ages are
Betty : 3x = 3*5 = 15
Mikey: 5 (x)
You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)
Answer: The current ages are

Yumi and Juan pick up litter along the highway at the same rate. Yumi picks up litter for 3 miles and takes 2 hours
longer than Juan, who picks up litter for 2 miles. If Juan spent x hours picking up litter, the following equation models
the situation
XX+2
How long did Yumi spend picking up litter?
1 hour 20 minutes
O 3 hours 20 minutes
4 hours
6 hours
its 6 hours
Answer:
6 hours
Step-by-step explanation:
Let's say that the number of hours that Yumi picked litter for is y.
You know that since Yumi picked litter for 2 hours more than Juan, y=x+2.
y=3m
x=2m
Subtract the second equation from the first:
y-x=m
Substitute:
x+2-x=m
2=m
This means that it takes 2 hours per mile of litter. Multiplying this by the 3 miles that Yumi walked makes a total of 6 hours. Hope this helps!

PLEASE SHOW YOUR WORK WITH YOUR ANSWER. Two bags had 50 kilograms of sugar each. After taking out 3 times as much sugar from bag one than bag two, bag one had half as much sugar left as bag two. How much sugar is left in each bag?
Answer:
Bag 1: 20
Bag 2: 40
Step-by-step explanation:
Let x be the amount taken out of bag 2
Then the amount left in each bag can be written as:
Bag 1: 50-3x
Bag 2: 50-x
Since we know that half of bag 2 is bag 1, that gives us:
50-3x = 1/2(50-x)
-> 50-3x = 25-x/2
Now lets isolate x and solve:
25 = 5x/2
-> 50 = 5x
-> x = 10
So plug x bag in for the original equations:
Bag 1: 50-3x = 50-3(10) = 20
Bag 2: 50-x = 50-10 = 40
