x + 16 = 64 |subtract 16 from both sides
x = 48
(x + 1) x (x - 4). When you check it you will get your original expression.
There are 180 degrees total in a triangle and the tell you one angle is 90. So you solve the equation 4x+6x=90. So x=9
It would go by (-4,2) then (0,-2) next would be (2,4)
Answer:
y = 8x + 15
Step-by-step explanation:
Let x represent the number of cds, and let y represent the total cost.
Since each cd is $8, we can represent the extra cost from cds with the term 8x.
And, since the membership costs $15, this cost can be represented in the equation by +15.
Put these together:
y = 8x + 15 will be the equation representing this
