Answers
Answer:
x = [tex]-\frac{9}{2}[/tex]
Step-by-step explanation:
=> 3+2(2x+8) = 1
=> 3+4x+16 = 1
=> 4x+19 = 1
=> 4x = 1-19
=> 4x = -18
Dividing both sides by 4
=> x = [tex]-\frac{18}{4}[/tex]
=> x = [tex]-\frac{9}{2}[/tex]
Answer: -9/2
Step-by-step explanation:
3 + 2(2x + 8) = 1
3 + 4x + 16 = 1
19 + 4x = 1
4x = -18
x = -18/4 = -9/2

Given a right triangle with b=3 and c=5 find leg a? Show your work
Answers
Find attached to this question, the diagram of the right angle triangle
Answer:
Leg a = 4
Step-by-step explanation:
A right angle triangle has 3 sides : side a, b and c
The formula to solved for a right angle triangle =
a² + b² = c²
In that above question,
a = unknown
b = 3
c = 5
Therefore,
a² + 3² = 5²
a² = 5² - 3²
a² = 25 - 9
a² = 16
a = √16
a = 4
Therefore, leg a = 4

Answer:
7/10
Step-by-step explanation:
Finding the totals of each column and row, we find:
There are 3+2+1 = 6 children in the baseball league.
There are 7+2+1 = 10 children in the softball league.
There are 3+7 = 10 children in the 7-9 division.
There are 2+2 = 4 children in the 10-12 division.
There are 1+1 = 2 children in the 13-15 division.
There are a total of 10+6 = 16 children.
We start with the information that the team is a member of the softball league. There are 10 children in this league; this is the denominator of the probability.
There are 7 children in the 7-9 division that are in the softball league. This gives us the probability 7/10.

240 people are going to a charity event 3/5 of the guests have ordered chicken for their meals of the remaining guests 12.5% have ordered gluten free meals how many people haven't ordered their meals yet?
Answers
Answer: 84 people
Step-by-step explanation:
From the question, 240 people are going to a charity event and 3/5 of the guests have ordered chicken for their meals. This means (3/5 × 240) = 144 people ordered chicken. Since 144 people have ordered, the number of remain people left will be:
= 240 - 144
= 96 people.
Out of the remaining guests which is 96, 12.5% have ordered gluten free meals. This means (12.5% × 96) = 12 ordered gluten free meals.
The people who haven't ordered their meals yet will be:
= 96 - 12
= 84 people.
Using the appropriate arithmetic operations, the number of guests who haven't made an order yet is 126
Total number of guests = 240Chicken orders = 3/5 × 240 = 144
Number left = 240 - 144 = 96
Gluten free meat = 12.5% × 144 = 18
Not yet ordered = 144 - 18 = 126
Therefore, the Number of guests who haven't made an order yet is 126

Suppose students are independent from one another. 63% of students are using Mr. Martin's new social media app, Mar-tin-stagram. 2 students are randomly selected. What is the probability that both of them use it? (Write answer as a decimal. Do not round)
Answers
Answer:
[tex]P(X=2) =0.3906[/tex]
Step-by-step explanation:
Proportion of students using the app, p = 63/100 = 0.63
Proportion of students not using the app, q = 1 - 0.63 = 0.37
Sample size, n = 2
Probability that the two students are using the app.
[tex]P(X = r) = nCr p^{n} q^{n-r} \\P(X = 2) = 2C2 *0.63^{2} *0.37^{2-2}\\P(X = 2) = 2C2 *0.63^{2} *0.37^{0}\\P(X=2) = 0.63^{2} \\P(X=2) =0.3906[/tex]

Answers
Answer:
C. (4,0)
Step-by-step explanation:
Given a graph of the system of equations
3x+4y=12; and
2x-y=8.
Line 1 passes through (0, 3) and (4, 0).Line 2 passes through (2, -4) and (4, 0).We can see that both lines pass through (4,0). Therefore, (4,0) is a point of intersection of the two lines.
It is therefore a solution to the system of equations.

Step-by-step explanation:
C = 5(F - 32)/9
so we do a little algebra here
9C = 5F - 160
we move both side
5F - 160 = 9C
5F = 9C + 160
so in the end
F =
[tex] \frac{9c + 160}{5} [/tex]
a = 9
b = 160
c = 5
Answer:
[tex]F=\frac{9C+160}{5}[/tex]
Step-by-step explanation:
[tex]C=\frac{5(F-32)}{9}[/tex]
Multiply both sides with 9.
[tex]9C=5(F-32)[/tex]
Use distributive property.
[tex]9C=5F-160[/tex]
Add 160 to both sides.
[tex]9C+160=5F[/tex]
Divide 5 to both sides.
[tex]\frac{9C+160}{5}=F[/tex]
rate of change for y=5x+25
Answers
Answer:5
Step-by-step explanation:
rate of change is the same thing as slope (or m)
The required rate of change for the given equation y = 5x + 25 is 5.
Given that,
For the given equation y =5x +25 the rate of change is to be determined.
The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
What is the rate of change?The rate of change is defined as the change in value with the rest of the time is called rate of change.
Here,
The given equation,
y = 5x + 25
Differentiate the above equation with respect to x,
dy/dx = d(5x +25)/dx
dy/dx = 5dx/dx + d25/dx
dy/dx = 5 (since dx/dx =1 and d25/dx = 0)
here dy/dx is the slope of the equation or m or rate of change = 5
Thus, the required rate of change for the given equation y = 5x + 25 is 5.

Step-by-step explanation:
A function of x means that there can only be one value of y per x value. Therefore, D does not match this because there are 4 values of y per x value (3).
Answer:
D
Step-by-step explanation:
Each x value can have only ONE y value
this means that there cannot be more than one of the same x value:
think of the x values as an input, each input has one output right?
ex:
input: 7
output:8
input:3
output:2
how is it possible that the same input has different outputs?
input: 5
output: 6,7
this does not make any sense, one input should only have one output hence, one value of x(input) should have only one value of y(output)

The last 4 rows are the same: 3 + x, 1 negative. What factors does Jenna need to model for the sides? (3x + 1) and (x – 4) (3x – 1) and (x + 4) (3x – 2) and (x + 2) (3x + 2) and (x – 2)
Answers
Answer:(3x – 1) and (x + 4)
Step-by-step explanation:
Jenna needs to model the factors (3x – 1) and (x + 4) for the sides of the configuration. The correct answer would be an option (B).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.
The model is given in the question, as follows:
3x² + 11x – 4
Each row has a coefficient of 3 and an x term, which can be modeled with 3 tiles and 1 tile, respectively.
The first row has a constant term of -1, which can be modeled with 1 tile in the Factor 1 spot.
The second row has a constant term of 4, which can be modeled with 4 tiles in the Factor 2 spot.
So, the configuration shows the correct factors (3x – 1) and (x + 4) for the sides of the model.

The dimension of the rectangular prism will be 3 units long, 5 units wide, and 1 unit high. Then the diagonal of the prism is given as,
D² = 3² + 5² + 1²
Simplify the equation, then we have
D² = 3² + 5² + 1²
D² = 9 + 25 + 1
D² = 35
