Answer:

Step-by-step explanation:
Let w and l be the width and length of the garage.
Let
and
be the area of garage at present and new garage.
Given:
The area of the garage at present

And he planed to tripling the dimensions of the garage.
We need to find the area of the new garage.
Solution:
We know the area of the rectangular garage.


---------------(1)
The dimension of the new garage is triple, so the area of the new garage is.


Substitute
from equation 1.


Therefore, the area of the new garage

Step-by-step explanation:
So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
Answer:
160 inches
Step-by-step explanation:
Area = L times W
In a rectangle, there are 4 sides
2 are width
2 are length
56 is total
8 + 8 = 16
56 - 16 = 40
40 is what is left for the 2 length sides
since there are 2 sides and they need to be equal, we divided 40 by 2
40 / 2 = 20
the length of one side is 20
area = 8 times 20
a = 160 inches
The given equation of the line is in slope - intercept form where the slope is 3 and the y - intercept is 2. The line perpendicular to the given has a slope which is equal to its negative reciprocal. Thus, the slope of a line perpendicular to y = 3x + 2 is -1/3. The answer is letter D. -1/3
