Answer:
f(x) = 2ˣ + 1
Step-by-step explanation:
Based on the exponential increase, you know that it will be an exponential equation, meaning that you can cancel out the first two options.
The easiest way to do pick the between the two remaining equations is by plugging in an x-value and seeing if the y-value for that equation matches the y-value from the equation.
For (3, 9):
f(x) = 3ˣ = 3³ = 27
f(x) = 2ˣ + 1 = 2³ + 1 = 8 + 1 = 9
The last equation is the equation that is represented by the table.
f(x)=-x^2-14 find f(9)
Answer:
Step-by-step explanation:
f(x) = -x² - 14
f(9) = -9² -14 = -81-14 = -95

Hi algebra is hard please help: The expression (8x+ 4) inches represents the perimeter of a rectangle whose width is (3x − 4) inches. Find the length of the rectangle if x = 2
Answer:
Length = 4 inches
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
If x = 2
Perimeter = 8x - 4
= 8(2) - 4
= 16 - 4
= 12 inches
Width = 3x - 4
= 3(2) - 4
= 6 - 4
= 2 inches
Perimeter of a rectangle = 2(length + width)
12 = 2(length + 2)
12 = 2length + 4
12 - 4 = 2 length
8 = 2 length
Length = 8/2
Length = 4 inches

plz help find x !!!!!
Answer:
a. 38.5
Step-by-step explanation:
The triangles are similar. That means that the ratios are the same.
x/14 = 11/4
x/31.5 = 11/9
Let's use the top one
x/14 = 11/4
4x/14 = 11
4x = 154
x = 38.5
A) Find the Volume enclosed by the curve =6−22 and the x-axis when it is rotated once around the x-axis.
Answer:
hello your question is not well written hence i will give you a more general answer assuming a region that is enclosed by curves y = x and y = x^3
answer : 8/21
Step-by-step explanation:
y =x , y = x^3
next determine the intersection point which is
x = x^3
x( x^2 - 1 ) = 0
therefore ; x = 0 , 1 , -1

Hello There!
So the sum of the cakes (y) and cookies (x) is 64
so x + y = 64
It says that the amount of cookies he sold was 4 less then 3 times the number of cakes he sold
x = cookies
y = cakes
he sold 3 times the amount of cakes (y) - 4
so x=3y-4
So we can conclude that the answer would be D
