[tex](-2,-5)=(x_1,y_1)[/tex]

Substitute values into slope intercept form

[tex]y-y_1=m(x-x_1)\\\\y-(-5)=4(x-(-2))\\\\y+5=4(x+2)\\\\y+5=4x+8\\\\y=4x+8-5\\\\y=4x+3[/tex]

Step-by-step explanation:

The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;

[tex]\frac{5}{7}+ \frac{10}{1} \\The \ LCM \ is \ 7\\\\= \frac{5(1)+10(7)}{7}\\\\= \frac{5+70}{7}\\\\= \frac{75}{7} \\\\= 10 \frac{5}{7}[/tex]

Hence the expression written in equivalent form of common denominator is [tex]\frac{5 + 70}{7}[/tex]

The sum is [tex]10 \frac{5}{7}[/tex]

Answer:

432 seats

Step-by-step explanation:

Since 24 seats = 1 row, all we have to do is multiply 24 by 18, since there are 18 rows of seats. This would give us 432, which is the total number of seats in the auditorium.

Step-by-step explanation:

The perimeter of a figure is the distance around the outside of the figure. To find the perimeter of this figure, we need to add the lengths of all sides. This is:

P = A + B + C + D

P = x² + 4x + 8 + 2x² + x

P = 3x² + 5x + 8

The perimeter is 3x² + 5x + 8.

Answer:

71/100

Step-by-step explanation:

Action 29 plus comedy 42 equals 71 and if you add action, comedy, drama, and horror you get your denominator of 100

Fraction of the students is 71/100 who were surveyed prefers comedy or action movies.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

We have to given that;

Number of students who prefer action = 29

Number of students who prefer comedy = 42

Here, Total students = 100

Hence, Fraction of the students who were surveyed prefers comedy or action movies is,

⇒ 29/100 + 42/100 = 71/100

Answer:

what do i answer lol

Step-by-step explanation:

Answer:

4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.

Step-by-step explanation:

Let w = wooden block

Let p = plastic bricks

Given the following data;

Price of wooden block per pounds = $5

Price of plastic brick per pounds = $10

*Translating the word problem into an algebraic equation*

For the 10-pound mixture;

[tex] w + p = 10[/tex] .........equation 1

For the $80 mixture;

[tex] 5w + 10p = 80[/tex] ..........equation 2

Solving the linear equation by using the substitution method;

Making w the subject in equation 1:

[tex] w = 10 - p[/tex] .......equation 3

Substituting "w" into equation 2;

[tex] 5(10 - p) + 10p = 80 [/tex]

Simplifying the equation, we have;

[tex] 50 - 5p + 10p = 80 [/tex]

[tex] 50 + 5p = 80 [/tex]

Rearranging the equation, we have;

[tex] 5p = 80 - 50[/tex]

[tex] 5p = 30 [/tex]

[tex] p = \frac {30}{5} [/tex]

p = 6 pounds (For the plastic brick).

To find w;

Substituting "p" into equation 3;

[tex] w = 10 - 6[/tex]

w = 4 pounds (For the wooden block).

The answer is C)Spelling Scores vs. Hours Spent Studying

Step-by-step explanation:

This is the answer because if you look at all of the other options, then you will see that they have a steeper slope, you could also calculate and find for slope if u are still unsure :) hope this helps

The graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph

The slope of a line is the quotient of the change in the vertical values to the corresponding horizontal values

Check below on how the trend line with the least slope can be determined

From the question, we have:

The slope (m) is calculated using:

m = (y₂ - y₁)/(x₂ - x₁)

So, we have:

The line 3 has the least slope

i.e. m₃ = 2.5

Hence, the graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph

Answer:

A)

[tex]y=10.25x[/tex]

B)

24 hours

C)

$410

Step-by-step explanation:

We are given that Kelly’s paycheck varies directly with the number of hours she works.

We know that she received $133.25 for 13 hours of work.

Part A)

The standard form for the direct variation equation is:

[tex]y=kx[/tex]

Where k is the constant of variation.

Here, y is the paycheck amount and x is the number of hours Kelly worked.

We know that Kelly received $133.25 for 13 hours of work. Hence, y = 133.25 when x = 13:

[tex]133.25=13k[/tex]

Solve for k:

[tex]k=10.25\\[/tex]

Therefore, our constant of variation is 10.25.

We can substitute this into our equation:

[tex]y=10.25x[/tex]

Therefore, our direct variation equation is:

[tex]y=10.25x[/tex]

Contextually, the equation tells us that Kelly earns $10.25 per hour.

Part B)

Using the equation, we can determine the the number of hours Kelly worked to earn $246. We can substitute 246 for y:

[tex]246=10.25x[/tex]

Solve for x:

[tex]\displaystyle x=\frac{246}{10.25}=24[/tex]

Therefore, x = 24.

Therefore, Kelly must’ve worked 24 hours for her paycheck to be $246.

Part C)

We can use our equation. This time, we will substitute 40 for x and evaluate. Hence:

[tex]y=10.25(40)=\$410[/tex]

So, Kelly will earn $410 for working 40 hours.

Answer:

The value of n will be:

Step-by-step explanation:

Given the expression

[tex]\frac{n}{2}-8^{-1}=11[/tex]

Apply the exponent rule:

so the expression  becomes

[tex]\frac{n}{2}-\frac{1}{8}=11[/tex]

Add 1/8 to both the sides

[tex]\frac{n}{2}-\frac{1}{8}+\frac{1}{8}=11+\frac{1}{8}[/tex]

[tex]\frac{n}{2}=\frac{89}{8}[/tex]

[tex]n=\frac{89}{4}[/tex]

Answer:

(a)  [tex]3x^2 + 27y^2 + z^2 - 18xy + 6 \sqrt{3} yz -2 \sqrt{3} zx[/tex]

    this can be written as

     [tex](-x\sqrt{3})^2 + (y3\sqrt{3})^2 + (z)^2 +2 ( -x\sqrt{3} )( y3\sqrt{3}) + 2( y3\sqrt{3})(z) + 2(z)( -x\sqrt{3})[/tex]

    which is equivalent to

    [tex]a^2+ b^2 + c^2 + 2ab + 2bc + 2ac = (a+b+c)^2[/tex]

     [tex](-x\sqrt{3} + y3\sqrt{3} + z)^2 = (-x\sqrt{3} + y3\sqrt{3} + z)(-x\sqrt{3} + y3\sqrt{3} + z)[/tex]

(b)[tex]27 x^3 + 125y^3[/tex] = [tex](3x)^3 + (5y)^3[/tex]

which is same as [tex]a^3 + b^3 = (a+b)(a^2 +b^2 -ab)[/tex]

                    = [tex](3x + 5y)(9x^2 + 25y^2 -15xy)[/tex]

(c) [tex](2a - 3b + c )^2[/tex] = (2a -3b +c)(2a -3b+c)

(d) [tex]a^3 + b^3 + 125 c^3 - 15 a b c[/tex]

this is same as

[tex]a^3 + b^3 +c^3 - 3abc[/tex] = [tex](a+b+c)( a^2+b^2+c^2 -ab-bc-ac)[/tex]

     = [tex](a + b + 5c)(a^2+b^2 +25c^2 -ab -5bc -5ac)[/tex]

(f) [tex]x^4 y^4 - x y64^4 = xy( x^3y^3 - 64^4) = xy( x^3y^3 - (256)^3) \\ = xy( xy - 256 )(x^2y^2 + 65536 + 256xy)[/tex]

(using the property of  [tex]a^3 -b^3 = (a-b)(a^2+b^2 +ab)[/tex] )

(g) [tex]8x^3 - (2x - y)^3 = (2x)^3 - (2x-y)^3 \\ = (2x - 2x + y)(4x^2 + (2x-y)^2 + 2x(2x-y))\\ = y(8x^2 + y^2 -6xy +4x)[/tex] using the same property above

Answer:

45

Step-by-step explanation:

basically what we are trying to find is x + 4= square

for you to understand this better, take eg 5.

5  +   4 =       9

         |            \

four less than the square number( 9 is the square of 3)

we took the square of 3 and subtracted 4 from it making the result 4 less

12 + 4 = 16

         |            \

four less than the square number( 16 is the square of 4)

we took the square of 4 and subtracted 4 from it making the result 4 less

understanding that,

a)3

3 + 4 = 7

there is no square root of 7   X

b)20

20 + 4 = 24

there is no square root of 24   X

c)37

37 + 4 = 41

there is no square root of 41   X

d) 45

45 + 4 = 49

the square root of 49 = 7

answer=49

Answer:B

Step-by-step explanation:

The new coordinates after dilation and the reflection across the y - axis will be (6, 3), (18, 3) and (6, 18).

A dilation is a transformation that enlarges or reduces a figure in size.

Given is figure [A] as shown in the figure which is dilated three times the size and is reflected across the y-axis.

Given are the coordinates of the triangle as -

(-2, 1), (-6, 1) and (-2, 6)

When the image is dilated by K, then each coordinate will become -

(x, y) = (Kx, Ky)

Therefore, the new coordinates will be -

(-6, 3), (-18, 3) and (-6, 18)

Now, in reflection across the y - axis, the coordinates will become (-x, y) from the coordinates (x, y).

Therefore, the final coordinates will be -

(6, 3), (18, 3) and (6, 18)

Therefore, the new coordinates after dilation and the reflection across the y - axis will be (6, 3), (18, 3) and (6, 18).

Slope of dotted/dashed line: -3

Slope of Reflection line: 0.25

Equation of Reflection line: y = 0.25x - 2

Step-by-step explanation:

Slope of dotted line: rise/run. So 3/1 = 3. It is a negative slop because of the way it is facing ( \ ).

Slope of reflection line: rise/run. So 1/4 = 0.25. It is a positive slope ( / ).

Equation of reflection line: y = mx + b

m = slope

b = y-intercept

y = 0.25x - 2
