<h3> Below we illustrate and prove that 7 and 21 multiply to 147 and add up to 28:</h3>

<h3>7×21=147</h3><h3>7+21=28</h3>

<h3>Are you asking because you are trying to figure out how to factor the following quadratic equation?</h3>

<h3>x2+28x+147=0</h3>

<h3>If so,the solution to factor the quadratic equation above is:</h3>

<h3>(x + 7) (x + 21)</h3>

<h3>To summarize,since 7 and 21 multiply to 147 and add up 28,you know that the following is true:</h3>

<h3>x2 + 28x + 147=(x+7) (x+21)</h3>

1 x 147 = 147
3 x 49 = 147
7 x 21 = 147
21 x 7 = 147
49 x 3 = 147
147 x 1 = 147

-1 + 29 = 28
-2 + 30 = 28
-3 + 31 = 28
1.25 + 26.75 = 28
2.50 + 25.5 = 28
3.75 + 24.25 = 28
1 + 27 = 28
2 + 26 = 28
3 + 25 = 28
12 + 16 = 28
13 + 15 = 28
14 + 14 = 28

The graph below shows the solution to which system of inequalities?
Rus_ich [418]

Inequalities help us to compare two unequal expressions. The inequalities that represent this graph are y<8/10x and y>-x. The correct option is C.

The complete question is:

The graph below shows the solution to which system of inequalities?

A.) y>x , y ≥ (8/10)x

B.) y>-x, y ≤ (8/10)x

C.) y>-x, y < (8/10)x

D.) y>x, y > (8/10)x

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

To find the inequality, we need to find the equation of the dashed line and then substitute the inequality as per the requirement. The dashed line is used instead of a solid line to show greater than or less than.

The inequality for the first graph can be written as,

y < \dfrac{8}{10}x

The inequality for the second graph will be,

y>-x

Hence, the inequalities that represent this graph are y<8/10x and y>-x. Thus, the correct option is C.

you have $18 to buy peppers. peppers cost $1.50 each. write and solve an inequality that represents the number of peppers you ca
Nezavi [6.7K]

At most 12 peppers can be bought with $18

Step-by-step explanation:

Given

Total amount for peppers = $18

Cost per pepper = $1.50

Let p be the number of peppers that can be bought from $18 at $1.50 per pepper

So,

1.50p\leq 18

Dividing both sides by 1.50

\frac{1.50p}{1.50}\leq \frac{18}{1.50}\\p\leq 12

Hence,

At most 12 peppers can be bought with $18
