please help :(

Answers

-- The points (0, 2.5) and (4, 2.5) are both 2.5 above the x-axis.

-- The line through them is a horizontal line. Its equation is y = 2.5 .

-- Any line perpendicular to it is a vertical line.

-- The vertical line through the point (3, -1) is the line x = 3 .

Select the inequality that models the problem. The sum of two consecutive odd integers is at least 80.

A: n + n + 2 ≥ 80
B: n+ n + 2 > 80
C: n + n + 1 ≥ 80
D: n + n + 1 > 80

Answers

You can use the fact that the term "at least" means less than or equal to.

The inequality that models the given problem is given by

Option A: n + n + 2 ≥ 80

How to form the inequality that models the problem?

We can convert the descriptions to mathematical symbols.

There is sum of two consecutive odd integers.

Consecutive means near each other in numbers counting. Since they are odd, and consecutive, thus, with difference of 2.

Let first odd number be n, then other will be n+2

Their sum is n+n+2

It is at least 80 thus, 80 or bigger than that.

Thus,

n+n+2 ≥ 80

That symbol ≥ is called bigger or equal and it means left side is either bigger or equal to the right value.

Thus,

The inequality that models the given problem is given by

Option A: n + n + 2 ≥ 80

Karina bought a camera with a regular price of $89. It was on sale at a 20% discount. There was a 7% tax on the sale price. How much did Karina spend to buy the camera?

Answers

1) we can calculate the price of this camera with 20% discount.
$89-(20/100)($89)=$89-0.2($89)=$89-$17.8=$71.2

2) now, we apply the tax on the sale price.
$71.2 + (7/100)($71.2)=$71.2+(0.07)($71.2)=$71.2+$4.984=$76.184

Answer: Karina spent to buy the camera $76.184.

Answer:

$17.18

Step-by-step explanation:

you can't have $17.184 it has to be two deci.
