Answer:
A ) 8.50x + 11 < 24x + 60
B ) 8.50x + 24 < 11x + 60
C ) 11x + 24 < 8.50x + 60
D ) 8.50x + 60 < 11x + 24
Step-by-step explanation:
Answer:
y = -7
Step-by-step explanation:
-3x – 2y = -25
Let x = 13
-3 * 13 -2y = -25
-39 -2y = -25
Add 39 to each side
-39+39 -2y = -25+39
-2y =14
Divide by -2
-2y/-2 = 14/-2
y = -7
Answer: 3x + 4y = - 26
Explanation:
1) the standard form is Ax + By = C
2) given: y + 5 = - (3 / 4) (x + 2)
3) multiply both sides by 4:
4y + 20 = - 3 (x + 2)
4) expand the parenthesis using distributive property:
4y + 20 = -3x - 6
5) transpose -3x and 20
4y + 3x = - 20 - 6
6) combine like terms
4y + 3x = - 26
7) rearrange:
3x + 4y = - 26
That is the standard form of the linear equation given.
