The width of a rectangle is 3x − 7. The length of the rectangle is 4x + 5. Find the area of the rectangle. Justify your result

Answer:

4.

Step-by-step explanation:

To find a function none of the x-values can be the same. For example, #1 isn't a function because 2 of the x values re 2 meaning it is not a function. #4 is a function because all of the x values are different numbers.

The perimeter of the rectangle is 2(x+y)

area of the rectangle is xy

Answer:

116

Step-by-step explanation:

so to find angle bcs we need to find x and to find x we need to create an equation. 160= angle scd +anglebcs so we do 180=3x+17+12x+8 and solve for x

160=3x+17+12x+8

step 1 combine like terms

160=15x+25

step 2 subtract 25 from each side

135=15x

step 3 divide each side by 15

9=x

then we plug in 9 to 12x+8 and get 116

Answer:

Step-by-step explanation:

First you want to mark 2 points. I chose (-2,0) and (2,2), it does not mater what points you chose. Once you have the two points, you need to find the slope. To calculate the slope can be seen below.

Slope (m) = ΔY/ΔX = 1/2 = 0.5

Once you have the slope, which is 0.5, you fill in this equation.

y = mx + b, where m is the slope and b is the y-intercept.

Now filling in given variables, you get this equation.

y = 0.5x + 1

A reflection over the line y = 3.

Step-by-step explanation:

You will draw a straight vertical line on 3 and then count the spaces. If you have equal space on both sides then your answer is right.

Answer vary:

(a)

*Laila is not wearing tennis shoes.

*It is not the case that Laila is wearing tennis shoes.

(b)

*Jassim is in Germany

Step-by-step explanation:

honestly in my opinion that’s my answer. to be honest either could be wrong but I’m fairly confident in part a but b I’m sorta confident.

(a) what you need to do is focus on the word negations and then you’ll see easily what the answers are. and that’s how I got the answers I got.

meaning of negations : the contradiction or denial of something

(b) so on part b your looking for the conclusion of the sentence and as the sentence explains “If Jassim’s spouse is happy, then Jassim is in Germany.” and for me I came to the conclusion of that answer.

Hi there!

1.Simplifly each terms:

[tex]3\frac{1}{4}= 3\frac{1}{4}[/tex]

[tex]\frac{1}{2}=\frac{2}{4}[/tex]

2.Convert the term into mixed number:

[tex]3\frac{1}{4}=4+4+4+1=\frac{13}{4}[/tex]

3.Subtract both terms:

[tex]\frac{13}{4}-\frac{2}{4}=\frac{11}{4}[/tex]

4.SimpIifly the fraction term:

[tex]\frac{11}{4}=2\frac{3}{4}[/tex]

This means W=2 3/4..

Answer:

✔ y = –4x + 5

✔ y = –2x + 3

Step-by-step explanation:

We can write -

The general equation of a straight line in slope intercept form -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

We have the given system of equations as -

y - 5 = - 4x

3y - 9 = - 6x

The given system of equations is -

y - 5 = - 4x

3y - 9 = - 6x

Now -

y - 5 = - 4x

y = - 4x + 5

and

3y - 9 = - 6x

3y = - 6x + 9

y = (-6/3)x + (9/3)

y = - 2x + 3

So, we can write -

The slope-intercept form of the first equation is y = - 4x + 5.

The slope intercept form of the second equation is y = - 2x + 3.

Therefore, we can write -

Answer:

y = -5/6x - 2

Step-by-step explanation:

The y-intercept is -2 because that is where the line crosses the y-axis Remember that slope is rise/run (there are many other terms for slope but this is the one I will reference). Therefore, the slope from one point to the next is down 5 and over 6. Since this is a decreasing slope (down 5), your slope will be negative

Answer:

Draw it like it would be sideways, or if the image you see turned to the left, on its side.

Step-by-step explanation:

Below is an example of it turning. Your shape is already on the center point, so it won't be moving along the X-axis and the center point can stay where it is. the shortest side of it should be facing the left side of your paper.

Answer:

1) Yes

2) No

Step-by-step explanation:

Substitute the x and y values of the given points into the equation and solve. If the result is a true statement, then they are solutions.

1) First, substitute the x and y values of (1,1.5) for the x and y in the given equation. Then, solve. (You can convert 1.5 from a decimal to a fraction, making it [tex]\frac{3}{2}[/tex].)

[tex]1.5= \frac{1}{4} (1) + \frac{5}{4} \\\frac{3}{2} = \frac{1}{4} +\frac{5}{4} \\\frac{3}{2} = \frac{6}{4} \\\frac{3}{2} = \frac{3}{2}[/tex]

The result is a true statement. Thus, (1, 1.5) is a solution to the equation.

2) Do the same with the point (12,4):

[tex]4 = \frac{1}{4} (12) + \frac{5}{4} \\4 = 3 + \frac{5}{4} \\4 = \frac{12}{4} +\frac{5}{4} \\4 \neq \frac{17}{4}[/tex]

The result is a false statement. The two values are not equal. Thus, (12,4) is not a solution to the equation.
