The solution to the inequality 2x<8 is x<4.

Step-by-step explanation:

Given inequality is;

2x < 8

For solving this inequality, we will divide both sides by 2 to find the value of x, therefore;

Dividing both sides by 2

$\frac{2x}{2}$

It means that x is less than four.

Thus,

The solution to the inequality 2x<8 is x<4.

Part A: Explain why x = 6 makes 4x − 5 ≤ 19 true but not 4x − 5 < 19. (5 points)

vovikov84 [41]

This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded

<h3>Inequality expression</h3>

Inequalities are equation not separated by an equal sign

Given the inequality expression

4x − 5 ≤ 19

4x ≤ 19 + 5

4x ≤ 24

x≤ 6

This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded

Given the equation

4x + 3 = 23

4x = 23 - 3

4x =20

x = 5

Hence 5 is the solution from the given set

Which graph shows the solution to the system of linear inequalities?

Vadim26 [7]

Answer:

Observe the attached image.

Step-by-step explanation:

We have the following linear inequalities

$y > \frac{2}{3}x + 3\\\\y \leq \frac{1}{3}x + 2$

Graph the lines corresponding to each inequality

$y > \frac{2}{3}x + 3$ → $y = \frac{2}{3}x + 3$

y = 3

$0 = \frac{2}{3}x + 3$

$-3 = \frac{2}{3}x$

$x = -4.5$

$y \leq \frac{1}{3}x + 2$ → $y = \frac{1}{3}x +2$

y = 2

$0 = \frac{1}{3}x + 2$

$-2 = \frac{1}{3}x$

$x = -6$

Now graph the two lines

For $y > \frac{2}{3}x + 3$

The region is made up of all the points that are above the line $y =\frac{2}{3}x + 3$

For $y \leq \frac{1}{3}x + 2$

The region is made up of all the points that are on the line and below $y = \frac{1}{3}x +2$

The final region will be the interception of both regions

Observe the attached image.

The system shown in the image you attached is:

$y > \frac{2}{3}x + 3\\\\y \leq -\frac{1}{3}x + 2$

Eight values have a mean of 7. a ninth value is added. the new mean is 9. what is the new value

My name is Ann [436]

Answer:

25 because the 8 values must times with 7 and will get 56. when the ninth value added , let the ninth value as y , 56+y , the new mean is 9 . so it will be like this , 56+y over 9 times with 9
