Answer:
2x + 4y = 16.
Step-by-step explanation:
14x - 7y = 8
Convert to slope-intercept form:
-7y = -14x + 8
y = 2x - 8/7
The slope is 2 so the line perpendicular to it has a slope of -1/2, so we have:
y = 1/2x + c
This line passes through the point (-2, 5) so:
5 = -1/2* (-2) + c
5 = 1 + c
c = 5 - 1 = 4
So our equation is y = -1/2x + 4.
Convert to standard from
4y = -2x + 16
2x + 4y = 16.
Answer: 5
explanation:
4m-2=6
———
3
multiply 3 on both sides to cancel the 3 out
4m-2=18
add 2 from both sides to cancel the 2 out
4m=20
divide both sides by 4 to cancel out the 4
Answer:
y=3x+2
Step-by-step explanation:
3x - y = -2
-3x -3x
_________
-y = -3x-2
/-1 /-1
_________
y = 3x+2
Answer:
w=3
Step-by-step explanation:
3(w+2)=15
Start by using the distributive property to distribute 3 to (w+2).
3w+6=15
Then, subtract 6 from each side.
3w=9
Divide each side by 3.
w=3
