Richie and Phoebe are saving money to buy a new tv. They need at least $510 to purchase the new TV. Phoebe weeds yards and Richi

den301095 [7]

Answer:

12x +9y ≥ 510
y ≤ 2x
y ≥ 25

Step-by-step explanation:

Phoebe earns 12x for her yard weeding, and Richie earns 9y for his dog walking. They want the sum of these earnings to be at least 510, so the first constraint inequality is ...

12x +9y ≥ 510

__

Richie plans to walk no more than 2x dogs, since y is the number of dogs he walks, the second constraint is ...

y ≤ 2x

__

Richie will walk at least 25 dogs, so ...

y ≥ 25

What is |-8| ? -16

olga nikolaevna [1]

Answer:

8

Those little "sticks" are called absolute value.

For example, the absolute value of 2 is 2, and the absolute value of −2 is also 2. The absolute value of a number may be thought of as its distance from zero along real number line.

Thus, it doesn't matter if the number is positive or negative. As it only counts its distance from 0, on the number line.

I hope it helps.
