1) y=-x+4, the slope is -1
2)y=-x+4, slope is -1
3) yes
4)It's the same line if the slopes and y-intercepts are the same, so the number of corresponding points are infinite.
Answer:
Step-by-step explanation:
To the nearest tenth 8.238
=8.2 to the nearest tenth
47 times 22 = 1034
1034/2 = 517
380 is less than 517 so Renee has more than enough for each student.

Answer:
1065
Step-by-step explanation:
A right square pyramid consist of
- 1 base area which is a square, area of square = l²
- 4 triangles, area of a triangle = 1/2 (slant height)(base)
area of 4 triangle = 2 (slant height)(base)
In question we are given perpendicular height of pyramid not the slant height so first we will calculate the slant height.
By using pythagorus:
Slant height = √(24²+8²)
= 8√10
Surface area = baseArea + 2 (slant height)(base)
= 16² + 2( 8√10)(16)
= 1065
