Answer:
8x - 7y = 56
Step-by-step explanation:
in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7
so 8x - 7y = 56
-7y = 56 - 8x
y = 56/-7 -8x/-7
y = -8 + 8/7 x
Answer:
No (1,5) is not a solution
Step-by-step explanation:
if you try to solve this equation with the (1,5), you lay it out like 5 = 1/4 * 1 - 7. It turns into 5 = 1/4 - 7, because 1 times anything is that same number. Then you have to add 7 to both sides so that it cancels out on the right and you get 12 on the left. So you end up with the equation 12 = 1/4. This equation is not true, so therefore (1,5) is not a solution. Hope this helps :)
1/3
the denonator is 6 because that is the number of numbers there are, and the numerator is 2 because there are 2 numbers less than or equal to 16. you can simplify
Let the width of the rectangle be x
then the length is x+2
we are given the area as 80 square meter
and we know the area of a rectangle is given by
area=L*W
area=(x+2)*x
but our area=80
80=(x+2)*x
x^2+2x=80
x^2+2x-80=0
we use the quadratic formula to solve this which gives us
x=8
therefore our width is 8
and our length is 10
