Step-by-step explanation:
. 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?
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]
Is this a solution or an inequality? 5 - x < 8; x = -3
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.

There are 229 basketball fans who plan to go to a game. How many buses will be needed, given that each bus can hold 49 fans?
Answer:
5
Step-by-step explanation:
you divide the number of fans(229) by the number of people the buses can hold(49)
229÷49= ~4.6
because theres a decimal, you would have to add on a extra bus. so the answer would be 5
9. If f(x) = 5x-4 and f(2a) =156 , then what is the value of a?
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]f(x) = 5x - 4[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]f(2a) = 5(2a) - 4[/tex]
[tex]f(2a) = 10a - 4[/tex]
[tex]156 = 10a - 4[/tex]
[tex]10a - 4 = 156[/tex]
Add sides 4
[tex]10a - 4 + 4 = 156 + 4[/tex]
[tex]10a = 160[/tex]
Divide sides by 10
[tex] \frac{10a}{10} = \frac{160}{10} \\ [/tex]
[tex]a = 16[/tex]

A. 1
B. 6
C. 13
D. 17
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.

Step-by-step explanation:
Bcs when u have a closed circle is when is less or equal to, and an open circle means greater/less to. And you have a closed bcs is less or equal to. 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.)

Which ordered pair makes both inequalities true?
y > –2x + 3
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)
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.

A. f(x) = 10x + 8
B. f(x) = 15x + 3
O
C. f(x) = 0.5x + 1
D. f(x) = x + 18
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]
