What is the slope of the line through (-7,-8)(−7,−8)left parenthesis, minus, 7, comma, minus, 8, right parenthesis and (0,4)(0,4
ANEK [815]
Answer:
12/7
Step-by-step explanation:
When given two points, we can find the slope by using
m = (y2-y1)/(x2-x1)
= (4 - -8)/ (0 - -7)
= (4+8) / (0+7)
= 12/7
70. 180-120=60, and 180-60+50=70
Answer:
Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x = (x) , thus
(x) =
Evaluate g(3) and substitute the value obtained into (x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) = =
