Answer:
a = 
Step-by-step explanation:
4a -16 = a - 15
both left and right -a
then
4a - 16 -a = a - 15 -a
then
4a -a -16 = a -a -15
then
3a -16 = -15
both left and right + 16
then
3a -16 + 16 = -15 + 16
then
3a = 1
both left and right ÷3
then
3a ÷ 3 =1 ÷ 3
then
a = 
Your answer is (3,1) because if you graph the line that is the on off the line the other follow through
Answer:
8
Step-by-step explanation:
Let the width of the rectangle be x. Then the length would be x+2
Area=(length)*(width)
48=x(x+2), => x=6. Width is 6 and length is 8
Answer: The graph is attached.
Step-by-step explanation:
By definition, the line intersects the y-axis when
.
Then, in order to find the y-intercept, substitute
into the equation and solve for "y":

By definition, the line intersects the x-axis when
.
Then, in order to find the x-intercept, you can substitute
into the equation and then you must solve for "x". Then you get:

Knowing that the line passes through the points
and
, you can graph it (The graph is attached).
