Answer:
Solve one of the following equations for x or y and then substitute the answer to that equation into the second equation.
Step-by-step explanation:
Given the system of equations:
![x-y=7](https://tex.z-dn.net/?f=x-y%3D7)
![2x-y=17](https://tex.z-dn.net/?f=2x-y%3D17)
You could solve either one of the given equations but for this question we will solve the first equation.
![x-y=7](https://tex.z-dn.net/?f=x-y%3D7)
Solve for x
Subtract y
![x=5-y](https://tex.z-dn.net/?f=x%3D5-y)
Now substitute the answer for the first equation into the second equation.
Hope this helps.
Answer:
Step-by-step explanation:
In this case we will use the formula V= length × width × height
so, V= 2 1/4 × 1 × 1 1/4
=2 1/4 × 1 1/4
= 9/4 × 5/4
= 45/16
=2 13/16 cubic feet is the full capacity of the rectangular prism
then get the volume of the cube so, we will use the formula V= side times side times side
so, V= 1/4 times 1/4 times 1/4
V= 1/8 times 1/4
V= 1/32 cubic is the volume of the cube
then we will divide the full capacity of the rectangular prism to the volume of the cube
so, 2 13/16 divided by 1/32
so, 2 13/16 times 32/1
so, 45/16 times 32/1
=1,440/16
=90 small cubes can be packed in a rectangular prism in Part A
so, in Part B
V= 2 1/4 × 1 × 1 1/4
=2 1/4 × 1 1/4
= 9/4 × 5/4
= 45/16
=2 13/16 cubic feet is the volume of the rectangular prism

Step-by-step explanation:
m(x) = 0 when
(2x - 6)(x - 4) = 0
Equate each factor to zero and solve for x
2x - 6 = 0 ⇒ 2x = 6 ⇒ x = 3
x - 4 = 0 ⇒ x = 4
m(x) = 0 when x = 3 and when x = 4
The graph of m intercepts the x- axis at x = 3 and x = 4
The zeros of m are x = 3 and x = 4
Note that the x- intercepts and the zeros are the same values.
