Composite FunctionsCombining Like TermsStep-by-step explanation:
Step 1: Define
f(x) = x² + 6x + 7
g(x) = x + 2
g(f(x)) is x = f(x)
Step 2: Find g(f(x))
Substitute: g(f(x)) = (x² + 6x + 7) + 2Combine like terms: g(f(x)) = x² + 6x + 9Related Questions

B
220 inches
C
2695 inches
D
224 inches
Answers
Answer:
D. 224 inches
Step-by-step explanation:
Length of the new rectangle after dilation = 22 × ⁷/2 = 77 inches
Width of the new rectangle after dilation = 10 × ⁷/2 = 35 inches
Perimeter of rectangle = 2(length + width)
= 2(77 + 35)
= 2(112)
Perimeter = 224 inches

The difference between two whole numbers is 9. Twice the smaller number is 6 more than the larger. What is the smaller number?
Answers
Explanation:
27/3= 9
3x2= 6
The smaller number is 15
let
the larger number = x
the smaller number = y
Therefore,
The difference between the two whole numbers is 9 can be express as follows:
x - y = 9Twice the smaller number is 6 more than the larger. Therefore,
2y = x + 6Combine the equation.
x - y = 9
-x + 2y = 6
y = 15
x - 15 = 9
x = 9 + 15
x = 24
Therefore,
The larger number = 24
The smaller number = 15

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
You are going to attend night classes for 4 months. You have to earn an additional $987 for tuition within this time.
You decide to take a second job that pays $9 dollars an hour.
Taxes are 12% of your earnings, and you are able to save the rest.
Let x be the minimum number of hours you will need to work in order to save enough money for your tuition alone.
From the data given, we can frame a linear equation in one variable.
987 = 9x - 12% of 9x
987 = 9x - (0.12)(9)x
987 = 9x - 1.08x
7.92x = 987
x = 987/7.92
x = 124.62 ≈ 125 hours
Thus, the minimum number of hours you will need to work in order to save enough money for your tuition alone is 125 hours.

The y-intercept of any function is the value of the function when x = 0.
The y-intercept of f(x) is f(0) = 4(0) - 1. This is equal to -1.The y-intercept of g(x) is g(0), which we can see from the graph is 2.The y-intercept of h(x) is h(0), which is cos(0 + 2pi). This is equal to 1.Therefore, g(x) has the greatest y-intercept.

Answers
Answer:
x = 2Step-by-step explanation:
These are equations of lines with different slopes, so there is only one point of their intersect.
The point of intersect is where f(x) = g(x).

x = 2
Answer: x = 2
Explanation:
From the way you were referring to the x-values as plural, I assumed there were multiple x-values and multiple points of intersection, but these are linear equations, so one x-value it is!
Simply f(x)=2(x-1)-5 into f(x)=2x-7. Just plug in 2x-7, in order to make it equal to -2x+1. That would make the equation 2x-7=-2x+1. Add 7 to both sides to make it 2x=-2x+8. Add 2x to both sides to make it 4x=8. Divide 4 to both sides and that results with x=2.
a flour company in minneapolis wants to know what percent of local households bake at least twice a week. A company representative calls 500 randomly selected local households from 8am to 5pm during the week and finds that 56% of them bake at least twice a week
Answers
Answer:
Step-by-step explanation:
The response of this would be to say that those people without daytime jobs that are outside the home, are more likely to be home and thus, have more time on their hands to attempt to bake. So basically, the quoted 56% is definitely going to be higher than the population percentage.
