Answer:16
Step-by-step explanation:
(3a-7)^2
1. 9a^2-21a-21a+49
2. 3a(3a-7)-7(3a-7)
3. (3a-7)(3a-7)
4. Combine like terms
Pandas and combine like terms
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
Answer:
m= 4, b = 3 matches with y = 4x +3
m=5, b = -2 matches with y = 5x - 2
m = 3, b = 4 matches with y = 3x + 4
m = -2, b=5 matches with y = -2x + 5
Step-by-step explanation:
Slope-intercept form is <em>y = mx + b</em><em> </em>in which m = slope and b = y-intercept
