Which point is an x-intercept of the quadratic functionf(x) = (x – 8)(x + 9)?

(0,8)
(0,–8)
(9,0)
(–9,0)

Answers

Answer 1
Answer: If you would like to find the x-intercept of the quadratic function f(x) = (x - 8) * (x + 9), you can do this using the following steps:

f(x) = (x - 8) * (x + 9)

(-9, 0): f(-9) = (-9 - 8) * (-9 + 9) = (-17) * 0 = 0
x = -9 and y = 0

The correct result would be (-9, 0).

Jake is buying a sweater with the price of 30 dollars the store is having a sell that will reduce the price by 30%. Sales tax of 5% will be added to the final purchase price what is jake total cost.

Answers

Answer:Jake's total cost is $22.05

Step-by-step explanation:

The initial price of the sweater is $30. The store is having a sell that will reduce the price by 30%. This means that there is a reduction in the original amount of the sweater by 30% which is expressed as

30/100 × 30 = $9

The new price of the sweater would be 30 - 9 = $21

Since a sales tax of 5% will be added to the final purchase price, the value of the tax would be

5/100 × 21 = 0.05×21 = $1.05

Jake's total cost would be

21 + 1.05 = $22.05

how would you write this word problem as an equation? When the gas gauge on her car was on the 3/8 mark, Karen pumped 15 gal. of gas into the tank in order to fill it. How many gal. of gas does the tank in Karen's car hold?

Answers

If the tank was 3/8 full, then it was 5/8 empty.
It took 15 gallons to fill those empty 5/8 of a tank.

5/8 x (1 tank) = 15 gallons

1 tank = 15 / (5/8) = 15 x 8/5 =24 gallons
