Answer:
The answer to your question is None of the options, the answer is y ≥ 1
Step-by-step explanation:
Inequality
5 - 3 (y + 2) ≤ 6y - 10
1.- Expand
5 - 3y - 6 ≤ 6y - 10
2.- Simplify like terms
-3y - 1 ≤ 6y - 10
3.- Add -6y in both sides
- 3y - 6y - 1 ≤ 6y - 10 - 6y
4.- Simplify
-9y - 1 ≤ -10
5.- Add 1 in both sides
-9y - 1 + 1 ≤ -10 + 1
6.- Simplify
-9y ≤ -9
7.- Divide both sides by -9 and change ≤ by ≥
-9/-9 y ≥ -9/-9
8.- Simplify
y ≥ 1
Step-by-step explanation:
slope-intercept form : y = mx + b
m = slope
b = y intercept
y = -5x +8

Answer:
x = 0
y = 4
Step-by-step explanation:
Given
12x - 5y = -20
y = x + 4
Substitute x + 4 for y in the first equation
12x - 5(x + 4) = -20
Expand the bracket
12x -5 X x - 5 x 4 = -20
12x - 5x - 20 = -20
7x - 20 = -20
Add 20 to both sides to eliminate -20 on the left side
7x - 20 + 20 = -20 + 20
7x = 0
Divide both sides by 7 to isolate x
7x/7 = 0/7
x = 0
Substitute 0 for x in either equation to get y
Using equation 2, we have
y = x + 4
= 0 + 4
= 4
x = 0
y = 4
