Answer:
point-slope form:
y - 10 = -4(x - -2)
y - 10 = -4(x + 2)
---
slope-intercept form:
y - 10 = -4x - 8
y = -4x - 8 + 10
y = -4x + 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x + 3y = 24
4x - y = 8
4x + 3y = 24
-4x + y = -8
4y = 16
y = 4
4x - 4 = 8
4x = 12
x = 3
(3, 4)
Answer:
15 shirts in one hour
Step-by-step explanation:
there are 60 minutes in an hour, 20 times 3 is 60, 5 times 3 is 15
Answer:
B
Step-by-step explanation:
You can just move upper y equation and it will be:
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
15x=30
x=2
