-9x+2> 18 OR 13+15 |< -4​

-9x+2&gt; 18 OR 13+15 |&lt; -4

Answers

Answer 1

Answer:

C. -16/9 < x < -19/13

Step-by-step explanation:

-9x + 2 > 18

~Subtract 2 to both sides

-9x > 16

~Divide -9 to both sides

x < 16/-9

13x + 15 ≤ -4

~Subtract 15 to both sides

13x ≤ -19

~Divide 13 to both sides

x ≤ -19/13

As we can see, there are two different solutions and the only option that shows this is C.

Best of Luck!

. A person weighing 120 pounds has about 20 pints of blood in their body. Which equation below represents the relationship between pints of blood, b, to a person's weight, w?

Answers

Answer:

[tex]w = 6b[/tex]

Step-by-step explanation:

Given

[tex]b = blood[/tex]

[tex]w = weight[/tex]

[tex]b = 20; when\ w = 120[/tex]

Required

Determine the equation that binds both parameters

First, we need to determine the constant of proportionality using:

[tex]w = k * b[/tex]

Where k represents the constant.

Substitute 120 for w and 20 for b

[tex]120 = k * 20[/tex]

Divide both sides by 20

[tex]6 = k[/tex]

[tex]k = 6[/tex]

Using the same formula, substitute 6 for k

[tex]w = 6 * b[/tex]

[tex]w = 6b[/tex]

Hence:

The equation is represented as [tex]w = 6b[/tex]

So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one

(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

Is this a solution or an inequality? 5 - x < 8; x = -3

Answers

Answer:

no, x=-3 is not a solution

Step-by-step explanation:

Plug in -3 as x.

5-(-3)<8

Distribute the -1 to the -3.

5+3<8

Add the 5 and 3.

8<8

8 is not less than 8, so -3 is not a solution to the inequality.

y < x – 2

On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) and (2, 0). Everything to the right of the line is shaded. The second dashed line has a negative slope and goes through (0, 3) and (1, 1). Everything to the right of the line is shaded.
(0,0)
(0,–1)
(1,1)
(3,0)

Answers

Answer:

its D. (3,0)

Step-by-step explanation:

The ordered pair makes both inequalities true is (3,0) if the inequalities are y > –2x + 3, and y < x – 2.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequalities are:

y > –2x + 3

y < x – 2

Plug the point in the above inequality:

(3,0)

The above point satisfy the inequality.

Thus, the ordered pair makes both inequalities true is (3,0) if the inequalities are y > –2x + 3, and y < x – 2.

[tex]f(2a) = 5(2a) - 4[/tex]

[tex]f(2a) = 10a - 4[/tex]

[tex]156 = 10a - 4[/tex]

[tex]10a - 4 = 156[/tex]

C. f(x) = 0.5x + 1
D. f(x) = x + 18

Answers

Answer:

A. [tex] f(x) = 10x + 8 [/tex]

Step-by-step explanation:

The equation in slope-intercept form, [tex] f(x) = mx + b [/tex], can be created to be used in finding Jack's pay. We need to find the slope (m) and the y-intercept (b) of the linear function.

Using two points (1, 18), and (1.5, 23), find the slope (m):

Slope (m) = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 18}{1.5 - 1} = \frac{5}{0.5} = 10 [/tex]

Find b, by substituting x = 1, f(x) = 18, and m = 10 into [tex] f(x) = mx + b [/tex].

[tex] 18 = (10)(1) + b [/tex]

[tex] 18 = 10 + b [/tex]

Subtract 10 from each side

[tex] 18 - 10 = b [/tex]

[tex] 8 = b [/tex]

[tex] b = 8 [/tex]

Substitute m = 10 and b = 8 into [tex] f(x) = mx + b [/tex].

✅Thus, the linear function that can be used to find Jack's pay would be:

[tex] f(x) = 10x + 8 [/tex]

The value of x is 13 if lines m and n are parallel and lines m and n are cut by transversal p.

What is linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

As we can see in the figure, the lines m and n are cut by transversal p.

Then the sum of angles mZ1 and mZ2 is equal to 180 degree.

4x + 14 +8x + 10 = 180

12x + 24 = 180

12x = 156

x = 13

Thus, the value of x is 13 if lines m and n are parallel and lines m and n are cut by transversal p.
