120 square feet
Answer:
D
Step-by-step explanation:
Given:
The equation of line is
To find:
The x and y-intercept of the given line.
Solution:
We have,
Putting x=0, we get
Add 6 on both sides.
Divide both sides by 4.
So, the y-intercept is 
.
Putting y=0 in given equation, we get
Add 5 on both sides.
Divide both sides by 7.
So, the x-intercept is 
.
Answer:
r = -1
Step-by-step explanation:
(y2-y1)/(x2-x1)=m
(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5
so plug in...
(4-7)/(4-r)=-3/5
then solve for r which will get that r = -1
numerator: 4-7=-3
denominator: 4-r=5 -> 4-5=0+r -> -1=r
So in this case, the solution is where the graphs intersect. Put the equations in y-intercept form.
-4x+y=-6
y=4x-6
8x-2y=14
-2y=14-8x
y=4x-7
These lines have the same slope, which is 4. Therefore, they are parallel. Parallel lines never intersect, so there is NO SOLUTION.
