First, divide -5 on both sides:
(x + 7) < -2
Then subtract 7 on both sides:
x < -9
x < -9 is your final answer.
For some of these, a calculator is helpul.

Answer:
30
Step-by-step explanation:
triangle ABC is proportional to triangle BCD so
hypothenuse of ABC/ ajdacent of ABC = hypotrnus BCD/ ajdacent of BCD
in short
AC/BC = BC/DC
10/x = x/3
10 . 3 = x²
x² = 30
x = √30
so the question mark is 30
Answer:
y = 2x - 1
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - (-3) / -2 - (-1)
-2/-1
= 2
y = 2x + b
-3 = 2(-1) + b
-3 = -2 + b
-1 = b
