Evaluate the function f(x) = 2x – 10 when x= -3,0, and 8.
f(-3) =
= 0
f(0) =
f(8) -

m∠a is 90°

m∠b is 40°

47

i need more details

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
