Answer: x=−2 or x=8

Step-by-step explanation:

Step 1: Factor left side of equation.

2(x+2)(x−8)=0

Step 2: Set factors equal to 0.

x+2=0 or x−8=0

x=−2 or x=8

Answer:

x = - 2, x = 8

Step-by-step explanation:

Given

2x² - 12x - 32 = 0 ( divide all terms by 2 )

x² - 6x - 16 = 0

Consider the factors of the constant term (- 16) which sum to give the coefficient of the x- term (- 6)

The factors are - 8 and + 2, since

- 8 × 2 = - 16 and - 8 + 2 = - 6, hence

(x - 8)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 8 = 0 ⇒ x = 8

Sarah currently earns $18.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 20% raise. How much wi
Pie

Answer:

21.6 $ / h

Step-by-step explanation:

Since it is a raise you'll calculate by multiplying the $ / h by (1 + % / 100)

In this case 1 + % / 100 = 1 + 20 / 100 = 1 + 0.20 = 1.20

1.20 * 18 = 21.6 $ / h

NB.:

If it was a decrease by 20 % => 1 - 20 / 100 = 1 - 0.20 = 0.80

You would multiply the $ by 0.80.

Graph the function y=2 sqrt x+4 and state the transformation from the parent graph y= sqrt x
Darya [45]

Answer:

Step-by-step explanation:

Please use parentheses so that there's no question about what constitutes the argument of the sqrt function:

y=2 sqrt x+4 → y = 2√(x + 4)

This result is obtained from y = √x by:

1) translating the graph of y = √x 4 units to the LEFT, and

2) stretching the resulting graph vertically by a factor of 2.

Five players on a basketball team in a game 4 players score 6 Points each the team scored a total of 34 points how many points d
Dmitrij [34]

Answer: The other player scored 10 points.

Step-by-step explanation:

Since we have given that

Number of players = 4

Number of scores each player score = 6

Total scores scored by 4 players would be

4\times 6\\\\=24

Total scores scored by a team = 34 points

So, the number of points scored by other player score is given by

34-24=10\ points

Hence, the other player scored 10 points.
