Answer:
Answers are in bold in explanation
Step-by-step explanation:
We are given the equation:
y = -7x + 8
The first x value is 0
y = -7(0) + 8
y = 8
(0, 8)
The next x value is 7
y = -7(7) + 8
y = -41
(7, -41)
Now we are given the Y value instead of X, so we do this:
36 = -7x + 8
Subtract 8 on both sides to leave -7x alone
28 = -7x
Divide by -7 on both sides to isolate x
-4 = x
(-4, 36)
Answer x = 24 + 3x

Answer:
204kg
Step-by-step explanation:
New percentage = 100% - 15%
since it is decrease we have to subtract both percentage.
so 100 - 15 = 85%
85% as a decimal = 0.85
To find the new amount, we have to multiply
240 x 0.85 = 204
Remember to add kg
Answer - 204kg
Where y=0
y=(x+8)(x-4)
0=(x+8)(x-4)
set to zero
x+8=0
x=-8
x-4=0
x=4
(x,y)
at (4,0) and (-8,0)
A is answer
Answer:
12.56
The circumstances of a circle can be found by multiplying pi by the diameter of the circle. If a circle has diameter of 4, its circumference is 3.14*4= 12.56. If you know the radius, the diameter is twice as large.
