Answer: A and D

Step-by-step explanation:

I took the test online and the answer is A and D the y intercept is the cost of her lunch and the slope is the cost of one book

The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch​.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

as, from the graph the slope tells us about the  cost of one book.

Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch​.

Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch​.

Answer: 16 acres

Step-by-step explanation: we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

substitute the values of x and y

The linear equation is equal to

Find out how many acres are on a farm with a total operating cost of $441,216

so

For y=$441,216

substitute in the linear equation the value of y and solve for x

Answer: 11.3 hours

Step-by-step explanation:

Before this question is another asking for an equation depicting this with Jordan's progress in miles (y) after a number of hours (x).

That would be y = 15x

x in the real world context would be the number of hours it would take for Jordan to finish the 170 mile bike race.

To solve this make y to be 170 and solve for x.

170 = 15x

x = 170/15

x = 11.3 hours

Answer:

she didnt go back from 15 she went back from 20and the arrows should be going backwords not forwards

The three errors that Emily makes are: The arrows should point in the negative direction. The arrows should end on negative 15. The arrows should start at zero.

The number line is a representation of numbers on the line which can be used for different arithmetic operations such as additions, subtractions, multiplication, and division of numbers and algebraic expressions. It usually starts from the origin 0 with the positive axis in the right direction and the negative axis in the left direction.

Answer:

114 pies

Step-by-step explanation:

If the pie get together only had 20 people with 15 pies, then each person had a portion of 3/4 (divide them). The pie party has 152 people with 3/4 portions each, which means there has to be 114 pies at the party (multiply them).

:)

Answer:

152÷20=7.6

7.6×15=114

114 pies

126 + 45 = 171

Step-by-step explanation:

Given:

The total price of apples (y) at an orchard can be calculated with the equation

[tex]y=1.25x+5[/tex]

where, x is the number of pounds of apples picked.

To find:

The interpretation of slope for the given situation.

Solution:

The slope intercept form is

[tex]y=mx+b[/tex]       ...(i)

where, m is slope and b is y-intercept.

We have,

[tex]y=1.25x+5[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=1.25, b=5[/tex]

Slope = 1.25.

We know that, y is total price of x pounds of apples picked and slope is change in y with respect to x.

Therefore, the slope of the given equation is 1.25 and it means the price increased by 1.25 for each additional pounds of apples.

[tex]t=\frac{s-6}{n-x}[/tex]

Step-by-step explanation:

[tex]nt+6-xt=s[/tex]

[tex]\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}[/tex]

[tex]nt+6-xt-6=s-6[/tex]

[tex]Simplify[/tex]

[tex]nt-xt=s-6[/tex]

[tex]nt-xt[/tex]

[tex]=t\left(n-x\right)[/tex]

[tex]t\left(n-x\right)=s-6[/tex]

[tex]\frac{t\left(n-x\right)}{n-x}=\frac{s}{n-x}-\frac{6}{n-x};\quad \:x\ne \:n[/tex]

[tex]t=\frac{s-6}{n-x}[/tex]

Therefor the value of t after arrangement is t = (s-6)/(n-x)

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.

Given equation is  nt+6-xt=s

Now solving for t by separately variables and constant :

 nt+6-xt=s

t(n-x) = s-6

t = (s-6)/(n-x)

Therefor the value of t after arrangement is t = (s-6)/(n-x)
