Step-by-step explanation:
solve and simplify to find
Number 18 is D) (3+8m)-7
Number 19 is:
1) z>1
2) z>-1
3) z<1
4) z<-1
Answer: 19.2 inches
Make a proportion:
4/25 = x/120
cross multiply
480 = 25x
Divide both sides by 25
X= 19.2
Answer: y + 1 = 2 (x -1)
Point slope form is:
y - y1 = m (x - x1)
Point on the line is (1, -1) and slope is 2
m = 2
y1 = -1
x1 = 1
y - (-1) = 2 (x - 1) or y + 1 = 2 (x -1)
