Answer:
(1,-4) and (3,-5)
-4+5/1-3
1/-2 , so the slope is -1/2
Y intercept is -3.5
ANSWER IS y=-1/2x-3.5
THANKSS :)
Answer:
408 sq. in.
Step-by-step explanation:
The total surface area of the pyramid is the sum of all 4 faces (each of them a triangle) and square base.
Triangle area is where b is base and h is height.
base of triangle is 12 and height is 11
So area of each triangle is
There are 4 of them, so total is 66 * 4 = 264
Now, square has an area of where s is the side length.
It is given s = 12, so the area of the square base is:
Total Surface Area of the Pyramid is 264 + 144 = 408 sq. in.
Answer:
9y+24
Step-by-step explanation:
2(3y+6)-3(-4-y)
Expand the brackets.
6y+12+12+3y
Rearrange.
6y+3y+12+12
Add like terms.
9y+24

Answer:
Step-by-step explanation:
One
The input is the top line. B is the output when multiplied by 4
B = 4A
Input A 12 15 47 34
Output B 48 60 188 136
Rule: 12 * 4 = 48; 15*4 = 60
Check the other two.
Two
B = A/2
Input A 44 56 18 26 20
Output B 22 28 9 13 10
Rule: 44/2 = 22; 56/2 = 28
Check the others.
