Evaluate the following piecewise function:
F(x)=2x-3, when <=-2

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

20%

step-by-step explanation:

there are no multiple choices

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)
