i would subtract 7 and divide by 4;
4x + 7 = 15
4x = 8
x = 2
Answer:
x = 1, y = 1
Step-by-step explanation:
Use system of equations to solve for x and y by using substitution
Answer:
y = mx + c
m = -4
at y intercept x = 0
(x,y) =(0,-3)
-3 = -4(0) + c
c = -3
therefore the answer is y = -4x + c
Answer:
The constant rate of change is the average change that happens between a time period. In slope-intercept form, it is the mx part of the equation.
y = mx + b
The answer is 2(2x-3)
Explanation: First you multiple 5 and 2 getting you ten
4x-10+4
Then you add -10 and 4 to get -6
4x-6
Finally you factor out the number to and divide both the 4 and -6
2(2x-3)
