If s(x) = 2 - x^2 and t(x) = 3x, which value iS equivalent to (s°f)(-7)?

Step-by-step explanation:

(s∘t)(-7) = s(t(-7))

= s(3(-7))

= s(-21)

= 2 - (-21)²

= -439

x/3-10=8

x/3=18

x=48

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
