Answer: 6.25
Step-by-step explanation:
Because corresponding sides of similar triangles are proportional,

Answer:
h(x) = x/4
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 4x
Exchange x and y
x = 4y
Solve for y
Divide each side by 4
x/4 = 4y/4
y = x/4
The inverse is
h(x) = x/4
Answer:
19x I believe
Step-by-step explanation:
Added 10 and 9, left the x
25% of 20 is 5. If 5 questions are B, the. the other 15 are not B.
(2z+43)=(-10z+25)
-2z -2z
43=-12z+25
-25 -25
18=-12z
z=-1.5
So Z=3/2
