Answer:
The slope would be C) -1/2
Step-by-step explanation:
To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -4)/(0 - 2)
m = 1/-2
m = -1/2
Multiply each cost by numbers starting from 0 then keep going until you get the same cost for each
Answer:
7
Step-by-step explanation:
did the question
S(x) = 2 - x²
t(x) = 3x
s(t(x)) = st(x)
s(t(x)) :
s(3x)
So in s(x) = 2 - x², to solve for s(3x) we replace x with 3x
s(x) = 2 - x²
s(3x) = 2 - (3x)²
= 2 - 9x²
st(x) = 2 - 9x²
st(-7) = 2 - 9*(-7)(-7)
= 2 - 9*49 = 2 - 441 = -439
st(-7) = -439
Answer:
y = -2x - 8
Step-by-step explanation:
The slope is -2 and the y-intercept is (0,-8).
Plug into the slope-intercept equation: y = mx + b.
