Answer:
12.5
Step-by-step explanation:
4/5r=10
multiply each side with 5
4/5r*5=10*5
4r=50
divide 4 from each side
4r/4=50/4
r= 12.5
Answer:
d
Step-by-step explanation:
3x times 5x equals 15x^2
3x times -5 equals -15x
---> 15x^2 - 15x
1st question : 16,22. 14,20. 12,18
Answer:
y = -1/5x + 8
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
f(x) = x + 10
Replace f(x) with y.
y = x + 10
Now, remember that in an inverse function you flip the x and y, so
x = y + 10
Solve for y
y = x - 10
because it's 2x... we must multiply by 2.
2y = 2x - 20
Original equation:
h(x) = 2x - 0
h(x) is 2y..
