Hi can someone help me on this please? I am having trouble understanding this one :) thx

Answer:

[tex] \large \boxed{y = 7x + 12}[/tex]

Step-by-step explanation:

Goal

Given

Step 1

[tex] \large{m = \frac{y_2-y_1}{x_2-x_1}}[/tex]

Substitute the coordinate points in the formula.

[tex]m = \frac{12 - ( - 16)}{0 - ( - 4)} \\ m = \frac{12 + 16}{0 + 4} \\ m = \frac{28}{4} \longrightarrow \frac{7}{1} \\ m = 7[/tex]

Step 2

[tex] \large{y = mx + b}[/tex]

Substitute m = 7.

[tex]y = 7x + b[/tex]

Step 3

Substituting any given coordinate points will give the same solution.

Step 3.1

[tex]y = 7x + b \\ 12 = 7(0) + b \\ 12 = 0 + b \\ 12 = b[/tex]

Step 3.2

[tex]y = 7x + b \\ - 16 = 7( - 4) + b \\ - 16 = - 28 + b \\ - 16 + 28 = b \\ 12 = b[/tex]

Step 4

[tex]y = 7x + b[/tex]

Substitute b = 12.

[tex]y = 7x + 12[/tex]

Hence, the solution is y = 7x+12.

Hope this helps! Any questions about my answer can be asked in comments.

Answer:

B. 336. 38

Step-by-step explanation:

So, what you want to do is multiply the original price ($299) by the first markup percentage (150%)

299*1.50= $448.50

that is your markup price!

then you have to do the sale % (25%)

so you'll multiply your (25%) by your new price ($448.50)

448.50*.25= $112. 125

THIS IS NOT YOUR ANSWER!

don't forget that!

you will then subtract the sale price ($112.125) by the upcharged price ($448.50)

448.50-112.125= 336. 375

Round up then there is your answer!

= $336. 38

hope this helps!!

Answer:

Step-by-step explanation:

Answer:

Neither

Step-by-step explanation:

If f (–x) = f (x), then the function is even. if f (–x) = –f (x), (all the signs are flipped) the it is odd.

To apply this to the function here, simply replace the x in [tex](x-2)^{2}[/tex] with -x.

[tex](x-2)^{2}[/tex] = [tex]x^{2}[/tex] - 4x + 4, and [tex](-x - 2)^{2}[/tex] = [tex]x^{2}[/tex] +4x + 4.

Since [tex]x^{2}[/tex]+4x + 4 doesnt equal [tex]x^{2}[/tex] - 4x + 4 (even) or [tex]-x^{2}[/tex]+4x -4 (odd), the function is neither even nor odd.

Step-by-step explanation:

Answer:

A. Odd

B. Positive Leading Coefficient

Step-by-step explanation:

When it comes to degree - Odd degrees start from below the x axis and end over the y axis

For leading coefficients - Positive leading coeffcients always start from below, since we know the degree is odd, this leading coefficient fit.

Answer:

The measure of angle B is 54°. The measure of angle A is 51°. The measure of angle AFE is 47°.

According to exterior angle theorem: It a triangle

Exterior angle = Sum of opposite interior angles

In triangle BED,

The measure of angle B is 54°.

In triangle ABC,

The measure of angle A is 51°.

In triangle AEF,

Using angle sum property,

Therefore the measure of angle AFE is 47°.

Answer:

Step-by-step explanation:

Angles across the top must equal 180 and all angles within the triangles must equal 180.

Answer: She can read 1.2 chapters of her book in one hour.

Step-by-step explanation:

When we have a relation of: "doing something" in a given "amount of time"

The rate at which you can do that activity per unit of time is:

R = (how much you did)/(time it took)

In this case, we know that

"Tory reads 4/5 of a chapter in 2/3 of an hour"

Then the rate, in this case, could be calculated as:

R = (4/5 chapters)/(2/3 hour) = 1.2 chapter per hour.

This means she can read 1.2 chapters of her book in one hour.

The line of best fit, runs closest to most points.

i hope this helps :)

(0, 9.5) and (10, 1.5) can be joined to draw most accurately the line of best fit on this scatter plot.

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points.

It is that line which is closest to all the points. For example, in this question, the line joining points (0,9.5) and (10,1.5) is the line of best fit.

Answer:

70 degrees

Step-by-step explanation:

In the parallelogram  KLMN, the sum of the adjacent angle is 180 degrees

Hence;

m<K + m<L = 180

110 + m<L = 180

m<L = 180-110

m<L = 70degrees

Hence the measure of m<l is 70 degrees

Answer:

x=-3

Step-by-step explanation:

Because its straight, on the x-axis, and on -3.

===========================================================

Explanation:

This green line goes through -3 on the x axis. Every point on this line has the same x coordinate and that x coordinate is x = -3. For instance, the two points (-3,5) and (-3,2) are on this green line. The equation of this line is x = -3 to indicate that x must be -3, but y can be anything you want. So that's why the y term doesn't even show up here. We cannot write the equation into slope intercept form. The slope of any vertical line is undefined.

Step-by-step explanation:

Remark

I'm going to assume that the edges of the cubes are 1/2 inch on each side.

V = 1/2 * 1/2 * 1/2 = 1/8 cubic inches.

Volume of the box

V = L * w * h

Givens

L = 2 inches

w = 3.5 inches

h = 5.5 inches

Solution

V = L * w * h

V = 2 * 3.5 * 5.5

V = 38.5

1/8 has the decimal equivalent value of 0.125

Number of cubes needed = Volume of the box / volume of the cube

Number of cubes needed = 38.5 / 0.125

Number of cubes needed = 308
