Answer:

Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to 


substituting the value of y in
:

substituting x=-1 in y= -4-5x:
(upon solving, you should get this)

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)


-1= 2 x 1 +c
-3=c
Answer:
A) x + x+1 + x+2
We don't need equation A)
B) 3*(x+2) = (x + X+1) +102
3x + 6 = 2x + 1 + 102
x = 97
Numbers are 97, 98 and 99
Step-by-step explanation:
(1,-6)(-5,2) distance is 10

I believe its C i saw this yesterday somewhere not 100% sure
Step-by-step explanation:
Answer:
The answer is 792.
Step-by-step explanation:
I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.
All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.
