Y/-2 + 5 = 13
y/-2 = 13 - 5 = 8

Answer:

y=-16

Step-by-step explanation:

The expression is written:

-y/2+5=13

We multiply the whole expression by 2 to get rid of the fraction:

-y+5\cdot(2)=13\cdot(2)

-y+10=26

We move -y to the right hand side to make it positive y and move 26 to the left side to subtract it from 10:

10-26=y

y=-16

Dovator [93]

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is -8x^2 + 54x + 140.

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

=-8(0)^2 + 54(0) + 140

=140

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
