The answer to this question is b
Answer:
13
Step-by-step explanation:
8/2=16/4
=4
x-3=2.5*4
x=10+3
x=13
Based on the graph,
f(x) = 1/2x+3
g(x) = -x+4
so, h(x) = -1/2 x +7
Since h'(x) is the derivative or slope of h(x) and h is a line,
h'(x) = -1/2, Answer C.
Answer:
x=10
y=-10
Step-by-step explanation:
multiply first row by 7
14x−21y=350
7x+8y=−10
multiply second row by 2
14x−21y=350
14x+16y=−20
subtract the first row by the second row
−37y=370
solve for y
y=−10
substitute y=-10
14x−21×−10=350
solve for x
x=10
and thats your answer
x=10
y=-10
