SOMEONE PLEASE HELP MEEE!!!! HOW DO YOU DO THIS

Answer:

y = − 2/5x − 11

Step-by-step explanation:

To answer this, we need to put it into y = mx + b form. First, we need to find the slope. The equation for that is:

[tex]m = \frac{-9 - (-7)}{-5 - (-10)}[/tex]

[tex]m = -\frac{2}{5}[/tex]

We now have the slope. Now, we need to figure out b, or the y-intercept. Using y = mx + b, we substitute the slope and an x value (it doesn't matter whether it's -10 or -5, but let's use -10 for now) and a y value (same thing).

[tex]-7 = (-\frac{2}{5})(-10) + b[/tex]

[tex]b = -11[/tex]

All that's left to do is plug it in! Our final answer is:

[tex]y = - \frac{2}{5}x - 11[/tex]

Answer:

[tex]y = - \frac{2}{5} x - 11 [/tex]

Step-by-step explanation:

[tex] (-10,-7) and (-5,-9) \\ x_{1} = - 10 \\ y_{1} = - 7 \\ x_{2} = - 5 \\ y_{2} = - 9[/tex]

[tex] \frac{y - y_{1}}{x -x_{1} } = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } \\ \frac{y -( - 7) }{x - ( - 10)} = \frac{ - 9 - ( - 7)}{ - 5 - ( - 10)} \\ [/tex]

[tex]\frac{y + 7}{x + 10} = \frac{ - 2}{5} \\ cross \: multiply \\ 5(y + 7) = - 2(x + 10) \\ 5y + 35 = - 2x - 20[/tex]

[tex]collect \: like \: terms \: \\ 5y = - 2x - 20 - 35 \\ 5y = - 2x - 55 \\ \frac{ 5y = - 2x - 55}{ 5} \\[/tex]

[tex]y = - \frac{2}{5} x - 11[/tex]

Answer:

Choices B, D and E.

Step-by-step explanation:

This is simple logic.

If it was choice A, number of outfits won't be lower than number of days.

Choice B is right, because if you do this:

(3×2)(3×2)(3×2)=666 days

or

6÷3=2

(4×2)(4×2)(4×2)=888 outfits

or

8÷4=2

You would know the statement is true.

If it was choice C, it's not correct:

(3×3)(3×3)(3×3)=999 days

(4×3)(4×3)(4×3)=121212 outfits (this is the closest answer because nothing can be multiplied by 4 to get 101010)

So, statement of choice C is incorrect.

Choice D is correct, because of this:

(3×4)(3×4)(3×4)=121212 days

or

12÷3=4

(4×4)(4×4)(4×4)=161616 outfits

or

16÷4=4

E is also correct, because of this:

(3×7)(3×7)(3×7)=212121 days

or

21÷3=7

(4×7)(4×7)(4×7)=282828 outfits.

So the answer is choices B, D and E.

I hope you understand my explanation.

Answer:

9 cm

Step-by-step explanation:

Every centemeter represents three. 3km=1cm.

The number of kilometers/3= the number of centemeters.

the number of centemeters x 3= the number of kilometers.

We now have three equations to help us covert back and forth.

The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)

The number of kilometers/3= the number of centemeters.

27/3=the number of centemeters.

Thus, the answer is nine.

Answer:

9cm

Step-by-step explanation:

1:3 this is the starting ratio

if we replace 3 for 27 we just divide them to get 9 so the new ratio is 9:27.

Resposta: 73 ° C

Explicação passo a passo:

Dado o seguinte:

Temperatura (T1) na decolagem localizada a 800 metros acima do nível do mar = 32 ° C

Temperatura (T2) à altitude máxima de 3200 metros acima do nível do mar = - 41 ° C

Portanto ;

A variação da temperatura externa entre o ponto de decolagem e a altitude máxima pode ser calculada por:

Diferença entre a temperatura de decolagem e a temperatura na altura máxima.

Variação externa da temperatura = (T1 - T2)

32 ° C - (-41 ° C)

= 32°C + 41°C

= 73°C

Answer: 2x = $90

Step-by-step explanation:

From the question, we are informed that Brady is selling candy bars for a school fundraiser to help pay for new sports uniforms and that he gets paid $2 for every candy bar he sells, and he made a total of $90 on Saturday.

The equation showing the number of candy bars Brady sold on Saturday goes thus:

Let the number of candy bars sold on Saturday be x.

Since each candy bar is sold for $2 and he made a total of $90, this means that the $90 gotten is the product of each candy bar and the amount sold which we represented by x. Therefore the equation will be:

2 × x = $90

2x = $90

We can further solve to get x.

2x = 90

x = 90/2

x = 45

That means 45 candy bars were sold.

Answer:

hi, so i belive the correct option to your question is:

2x = 90

Step-by-step explanation:

it just makes the most sense to me because 2x which could mean two times which in the equation it says he makes to dollars per candy bar sold, so it makes more sence for it to be 2x rather than 90x. and then it says he made a total of ninty dollars on saturday which is a key factor in solving this equation so think it would be 2x = 90$.

im really not sure if this logic makes sence, im not super good with algebra but i hope this helps you out.

Answer:

first complete the table by filling blank space on y axis

Then choosing a suitable scale, two squared box on the graph paper represent 1 unit for both axis.

Then draw a graph using x and y coordinate

(b) minimum value of y you dote a line from the turning point of the curve towards y axis then read the value

For this case it is -3.2

(c).To get the value of y when X=-3.5,

you dote alone from X =-3.5 on the X axis towards the curve vertically until you meet the curve then from the meeting point dote a line towards y axis and read the value.

which gives y=0.8

(d). draw a horizontal line at y=3 to meet the curve on both sides then dote a line from the meeting point vertically towards X axis and read the value on the X axis.

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = [tex]\frac{135}{45}=3[/tex]

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

[tex]a_n=a(r)^{n-1}[/tex]

[tex]a_n=45(3)^{n-1}[/tex]

Recursive formula of this sequence will be,

[tex]a_n=3(a_{n-1})[/tex], [tex]a_1=45[/tex]

Therefore, Option (B) will be the answer.

The perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Perimeter of a rectangle  = 2 (length and breadth)

the scale of the drawing is 1:500

let's assume that the length of the scale drawing playground is x and the breadth of the scale drawing playground is y. therefore, the length of the playground is 500x and the breadth is 500y.

Perimeter of the scale drawing playground = 2(length+breadth)

                                                                        [tex]= 2 (x+y)[/tex]

Perimeter of the real playground = 2(length+breadth)

                                                       [tex]=2 (500x+500y)\\=2 \times 500(x+y)\\= 1000 (x+y)[/tex]

Hence, the perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Answer:

[2,4]

Step-by-step explanation:

Answer:

The answer is option B.

-3 , - 0.9 , 45

Hope this helps you

Explanation:

The negative numbers are always smaller than the positive ones. So we list those first. The number -3 is smaller than -0.9 since it is further to left on the number line. So far we have -3 followed by -0.9. The last value must be 45 as its the only thing left. The sequence from smallest to largest is therefore -3, -0.9, 45. A number line is recommended to see the values being placed from left to right.

Answer:

The answers are options A and B

First solve the inequality

7x < 21

Divide both sides by 7

That's

7x/7 < 21/7

x < 3

The values that satisfy the inequality are

1 and 2 since they are both less than 3

Answer:

Simplifying

x = 2x + -21

Reorder the terms:

x = -21 + 2x

Solving

x = -21 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

x + -2x = -21 + 2x + -2x

Combine like terms: x + -2x = -1x

-1x = -21 + 2x + -2x

Combine like terms: 2x + -2x = 0

-1x = -21 + 0

-1x = -21

Divide each side by '-1'.

x = 21

Simplifying

x = 21

Answer:

c

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

We have:

[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right)[/tex]

Simply plug in each value:

When x = 7.9, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx 0.0012[/tex]

When x = 7.99, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0001[/tex]

When x = 7.999, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0000[/tex]

When x = 8.001, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0000[/tex]

When x = 8.01, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0001[/tex]

And when x = 8.1, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0012[/tex]

From this pattern, we can conclude that:

[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right) = 0[/tex]

Since as the limit approaches 8, the value gets smaller and smaller and approaches zero.

Graphing this, we can confirm our answer.
