Answer:
-4
Step-by-step explanation:
-5 + ______ = -9
-5 + -4 = -9
Answer:
-3x + 5y = -24
Step-by-step explanation:
The slope = (-9-(-6) / (-7 - (-2)
= -3 / -5
= 3/5.
Using the point-slope form of a straight line:
y - y1 = m(x - x1)
y - (-9) = 3/5(x - -7)
y + 9 = 3/5(x + 7)
Multiply through by 5:
5y + 45 = 3(x + 7)
5y + 45 = 3x + 21
-3x + 5y = -24 is the required equation.
Maybe this might help a bit what you have to do is subtract each fraction. if you subtract 1/3 and 3/4 and change the dinominators to mach then you answer will be 1/4 for a gallon of yellow paint and for blue paint you subtract and you do the same thing and for 7/8-3/4 your answer will be 1/8 after you have made equal denominator. 3/4 is the amount of paint being removed so that's what you will subtract
Do both as equation it will make it easier for her
