Answer:
x = 1
Step-by-step explanation:
1. Add 3x to both sides of the problem
- 4x + 3x - 7 = -3x + 3x
- -3x + 3x cancels out and leaves us with zero
- 7x - 7 = 0
2. Add 7 to both sides
- 7x (- 7 + 7) = 0 + 7
- -7 + 7 cancels out
- 7x = 7
3. Divide both sides by 7
To make sure our answer is correct we can plug in 1 to x in the problem
- 4(1) - 7 = -3(1)
- 4 - 7 = -3 : True
Answer:
-1 1/2
Step-by-step explanation:
Answer:
y=4x+64
Step-by-step explanation:
The slope intercept form is y=mx+b, m being the slope and b being the y-intercept
The line intersects the y axis at (0, 64), so the y intercept is 64
To find the slope, find the change in y over the change in x
The y decreases by 16 every time the x increases by 4
SO the slope is 16/4, simplified to 4
y=4x+64
Answer:
13.9
Step-by-step explanation:
7^2 + 12^2 = c^2
49 + 144 = 193
square root 193
and it’s 13.9
