Read the following scenario, which is represented by a polynomial expression. Then answer the questions to interpret the parts o

Effectus [21]

Answer:

x is the number of $1 increase in the price.

If there is no increase, then the total money earned is

2 × 70 = 140

If there is $1 increase, then the total money earned is

(2 + 1) × [70 - 8(1)]

If there is $2 increase, then the total money earned is

(2 + 2) × [70 - 8(2)]

If we continue the pattern, for x times $1 increase, total money earned is

(2 + x)(70 - 8x) = -8x^{2} +54x+140−8x2+54x+140

If we substitute x = 0 in the above equation, we will get

the total money earned = $140.

It means if there is no increase, then the total money earned = 140.

Hence, 140 is the constant term and it represents that there is no increase in price.

Step-by-step explanation:

9x - 5 = 7x + 25 ......(vertical angle and corresponding angle )

9x - 7x = 25 + 5

2x = 30

x = 30 / 2

x = 15
