Answer:
y= -10x+200, x is equal to a week
Step-by-step explanation:
formula y=mx+b
we lose 10$ a week so the slope is -10 and we start with a base amount of 200
so plug those numbers in and you have y= -10x+200
Answer:
They sold 468 rolls of wrapping paper

multipl how many boxes each of them sold by how many rolls were in each box. You get 252 rolls and 216 rolls. Then add both of those together to get 468 rolls of wrapping paper.
About the minus sign with 16, square root of -1 is an imaginary number i(iota). Also we know that square root of -16 will be multiplication of square root of -1 and square root of 16. So the final answer becomes, + or - 4i. Hope this helps
Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT
Hope this helped!
