Select the correct answer.<br> Choose the system of inequalities that best matches the graph below.
ANTONII [103]

Considering the linear functions on the graph, the inequality that matches the situation is:

B.

  • y \geq \frac{1}{2}x + 2
  • y \leq 2x + 1

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The lower bound of the interval is a linear function with y-intercept of b = 2, that also passes through (2,3), hence the slope is:

m = (3 - 2)/(2 - 0) = 1/2.

Hence the inequality is:

y \geq \frac{1}{2}x + 2

The upper bound of the interval is a linear function with y-intercept of b = 1, that also passes through (2,5), hence the slope is:

m = (5 - 1)/(2 - 0) = 2.

Hence the inequality is:

y \leq 2x + 1

Seven times a number is 28 more than three times that number​
Sauron [17]

Answer:

x=7

Step-by-step explanation:

The sentence can be rewritten as: (Replace "a number" with X)

7x=3x+28

1) Subtract a 3x from both sides:

4x=28

2) Divide both sides by 4:

x=7

It is the result when one-half of the sum of 24 and a number is all takrn away from three times a number . What is the number
mariarad [96]

I'm guessing your question was "88 is the result when one half of the sum of 24 and a number is all taken away from three times a number. What is the number?"

Answer:

40

Step-by-step explanation:

3X - (24+X)/2 = 88

5X - 24 = 176

5X = 200

X = 40
