Answer:
64
Step-by-step explanation:
2x(1/4 d)+d=96 (Rewrite the expression)
2x1/4d+d=96 (Reduce the numbers)
1/2d+d=96(Calculate)
3/2d=96 (Multiply both sides)
d=64
Answer:
the answer is this hope it helps

Answer: f(x) = (1/3)x + 3</h3>
This is basically in the form y = mx+b with m = 1/3 as the slope and b = 3 as the y intercept. I'm using f(x) in place of y to indicate function notation.
==========================================
Work Shown:
The goal is to solve for y.
x - 3y = -9
-3y = -9-x ... subtracting x from both sides
-3y = -x-9
y = (-x-9)/(-3) .... dividing both sides by -3
y = -x/(-3) - 9/(-3) ... break up the fraction
y = (1/3)x + 3 .... simplify
f(x) = (1/3)x + 3 .... replace y with f(x)

Answer:
D) ![y = 10 * 4^{x}](https://tex.z-dn.net/?f=y%20%3D%2010%20%2A%204%5E%7Bx%7D)
Step-by-step explanation:
Replace each function with x = 0
A) ![y = 1*4^{x} \\y = 1*4^{0} \\y = 1](https://tex.z-dn.net/?f=y%20%3D%201%2A4%5E%7Bx%7D%20%5C%5Cy%20%3D%201%2A4%5E%7B0%7D%20%5C%5Cy%20%3D%201)
B) ![y = 3*10^{x} \\y= 3* 10^{0} \\y = 3 \\](https://tex.z-dn.net/?f=y%20%3D%203%2A10%5E%7Bx%7D%20%5C%5Cy%3D%203%2A%2010%5E%7B0%7D%20%5C%5Cy%20%3D%203%20%5C%5C)
C) ![y = 2*4^{x} \\y = 2*4^{0} \\y = 2](https://tex.z-dn.net/?f=y%20%3D%202%2A4%5E%7Bx%7D%20%5C%5Cy%20%3D%202%2A4%5E%7B0%7D%20%5C%5Cy%20%3D%202)
D) ![y = 10*4^{x} \\y= 10*4^{0} \\y = 10](https://tex.z-dn.net/?f=y%20%3D%2010%2A4%5E%7Bx%7D%20%5C%5Cy%3D%2010%2A4%5E%7B0%7D%20%5C%5Cy%20%3D%2010)
If you check the graph with x = 0, the value of y is between 8 and 12 so the only probably answer acoording to the alternatives is D) which gives y = 10 when x = 0
