Answer: B
Step-by-step explanation:
To solve this problem, we first need to find the inverse of f(x). Then, you would plug in x=8. To find teh inverse, you switch y with x and x with y, then solve for y.
y=2x+5 [switch y with x and x with y]
x=2y+5 [subtract both sides by 5]
x-5=2y [divide both sides by 2]
y=(x-5)/2
Now that we have the inverse function, we plug in x=8 and solve.
y=(8-5)/2 [subtract]
y=3/2
Now, we know that f⁻¹(8)=3/2.
Answer:
24 square units
72 square units
96 square units
Step-by-step explanation:
In the figure attached, the complete question is shown.
One face is a rectangle with length = 12 and width = 8. Its area is: 8*12 = 96 square units
Another face is a rectangle with length = 12 and width = 10. Its area is: 10*12 = 120 square units
Another face is a rectangle with length = 12 and width = 6. Its area is: 6*12 = 72 square units
The other two faces are right triangles with base = 6 and height = 8. Their area is: (6*8)/2 = 24 square units
Answer:
1. y=4x-5 2. y=5x+3 3. y=-2x-8 4. 2/3x+2 5. y=-3/4x-2 6. 1/4x+7 7. -3x+2/3 8. 2/3x+10 9. -2x-1/2 10. -3/4x-3
Step-by-step explanation:
the slope always goes in front of the x and then the y-intercept goes after.
Answer:
6^2 = 36
Step-by-step explanation:
10^2 = 10 * 10 = 100
4^3 = 4 * 4 * 4 = 64
10^2 - 4^3= 100 - 64 = 36 = 6^2
