8 0

Answer:

See attached picture.

Step-by-step explanation:

h(x) has two functions in it. It has y = x and y =-x. Both have a slope of 1 or -1 and are diagonal lines. This means only 2 graphs of the four choices are possible answers.

Notice that y = -x has an interval that is greater than or equal to. This means it is marked with a closed or filled in dot at its start. This means choice B is the correct choice.

If you add 21 to my number and then multiply the result by 3, you will get 84 more than two-thirds of my number. Find my number.

Ksivusya [100]

Based on the calculations, the unknown number is equal to $\frac{-45}{7}$

Let the unknown number be x.

<h3>How to find an unknown number:</h3>

Translate the word problem into an algebraic expression, we have;

Adding 21 to the unknown number:

$21 +x$

Multiplying the result by 3:

$3\times (21+x)$

84 more than two-thirds of the unknown number:

$\frac{2x}{3} +84$

Equating the equations, we have:

$3\times (21+x) = \frac{2x}{3} +84\\\\43+3x=\frac{2x}{3} +84$

Cross-multiplying, we have:

$43+3x=\frac{2x}{3} +84\\\\129+9x=2x+84\\\\9x-2x=84-129\\\\7x=-45\\\\x=\frac{-45}{7}$

Your school's football team scored 49 points. Your team's score was 19 points more than the opponent's score s. Write and solve

solmaris [256]

Answer:

39 points

Step-by-step explanation:

Your school's football team scored 49 points.

Your team's score is 19 points more than the opponents score

The opponent score is represented as S

Since the total points that was scored is 49 and your team score is 19 then the equation can be written as follows

S+ 19= 49

Solve for S

S= 49-19

S= 30

Hence the opponent's score is 30 points

zheka24 [161]

Answer:

The Given Expression is

→ $26r^3s + 52r^5 -39r^2s^4\\13\times 2\times r\times r^2 \times s + 13\times 2\times 2\times r^2\times r^2\times r- 13 \times 3\times r^2\times s \times s^3\\\\\text{Taking out common factors}\\\\13r^2(2 rs + 2\times 2 r^3 -3 s^4)\\\\13r^2(2 r s+ 4 r^3 - 3 s^4)$

Option $13r^2(2 rs + 4 r^3 - 3 s^4)$ is correct option.

larisa86 [58]

Answer:

A) Canned and Packet

Grain, Meat and Vegetables

B) Let C = canned goods, let P = packet goods

20C + 7P

Let G = grain, let M = meat, let V = vegetables

7G + 3M + 17V

C) The number of grain and packet goods are the same in each expression, as this food group has been packaged in the same way.

The other variables in both expression are different. The meat and vegetable food groups have been separated in the second expression, whereas they are part of the same group in the first expression.
