2x + 4x - 21 = 0
6x - 21 = 0
6x = 21
x=3.5
Find the slope:
(-19 - 11) / (-8 - 2) = (-30/-10) = 3
Find the y intercept:
y = mx + b
11 = 3(2) + b
b= 5
So equation is:
y = 3x + 5

Answer:
5 / 28
Step-by-step explanation:
5/7 ÷ 20/5
= 5/7 x 5/20
= (5 x 5) / (7 x 20)
= 25 / 140 (divide numerator and denominator by 5)
= 5 / 28
Answer:
Step-by-step explanation:
if a is less than zero then b will from 4 down to negative infinity
so b < 4
