Answer:
Width = 7 inches
Length = 10 inches
Step-by-step explanation:
We know the 2(length + width) = 34, and we know that length = 3+width. Therefore, we can use substitution. 2(3+width+width) = 34, and we can see that the width is 7. The length of the rectangle is 7+3=10
B
If two lines have the same slope and different intercepts, then they will never cross each other; they are parallel lines. Therefore, they have no solutions since a solution is where the lines cross.
Answer:
x = 0 , x = 9
Step-by-step explanation:
to find the zeros let f(x) = 0 , that is
x(x - 9) = 0
equate each factor to zero and solve for x
x = 0
x - 9 = 0 ⇒ x = 9
Answer:
(A)If x represents the number of songs she downloads then it is a variable because of the AMOUNT of songs she downloads.
Step-by-step explanation:
For example if we had f(x)=2 the equation would be c=4.99+.75(2)
.75*2=1.50+4.99=
(6.49 = c) cost per month if she downloads 2 songs
