Answer:
4y = 3x + 4
3x-4y = -4 is correct
Step-by-step explanation:
This is what we do.
We first express the first equation in the form;
y = mx + c
where m represents the slope of the line
Thus we have;
4y = 3x -7
divide through by 4
y = 3/4x -7/4
Thus the slope here is the coefficient of x which is 3/4
Now, since the lines are parallel, it means that their slopes are equal
So the slope of the other line too is 3/4
We now use the point slope form to find the equation of this other line
Mathematically, that would be;
y-y1 = m(x-x1)
where (x1,y1) = (-4,-2)
Substituting this into the point slope equation, we have;
y-(-2) = 3/4(x-(-4))
y + 2 = 3/4(x + 4)
Cross multiply
4y + 8 = 3x + 12
4y = 3x + 12-8
4y = 3x + 4

52 yards
Step-by-step explanation:
Perimeter is all sides added together.
13 + 14 + 7 + 18 = 52
Answer:
Step-by-step explanation:
1 in = 190 ft
x in = 570 ft
We can use ratio and proportion to solve this problem.
The building will be 
tall in the scale drawing.
Remember you can do anything to an equation as long as you do it to both sides
2b+3c=14
minus 3c both sides
2b=14-3c
divide both sides by 2
