Answer:
See below.
Step-by-step explanation:
f(3) means the y-coordinate of the point that has x-coordinate 3.
To find f(3) using a graph of f(x).
Look up x = 3 on the x axis. If the function passes through that point on the x-axis, then f(3) is 0. If the function does not pass through that point, then go up or down till you intersect the function. Draw a horizontal segment left to the y-axis and read the point on the y-axis that the horizontal segment intersects. That is what f(3) is equal to.
Answer:
I think its part. No. D
Step-by-step explanation:
I DON'T KNOW
-3(x - 1) + 9 = 15
-3(x) + 3(1) + 9 = 15
-3x + 3 + 9 = 15
-3x + 12 = 15
- 12 - 12
-3x = 3
-3 -3
x = -1
It will be (7x+8)+(7x+8+7x=180
Answer:
10, 12, 14
Step-by-step explanation:
x-2, x, x+2
3x = 2 x ((x - 2) + (x + 2)) -12
3x = 4x - 12
x = 12
x-2 = 10
x+2 = 14
check: (10 + 14) x 2 - 12 = 48 - 12 = 36 = 3 x 12
