find the value of x​

Answer:

[tex]-9x+15[/tex]

Step-by-step explanation:

[tex]As\ the\ additive\ inverse\ of\ any\ number\ a\ is\ b,\ where,\\a+b=0\\Or, b=-a\\Hence, here, \\In\ order\ to\ find\ the\ additive\ inverse\ of\ 9x-15, we\ just\ add\ the\\ expression\ with\ b\ and\ equate\ it\ to\ 0.\\Hence,\\(9x-15)+b=0\\Hence,\\b=-(9x-15)\\b=-9x+15[/tex]

Answer:

There are 37 shirts in the batch.

Step-by-step explanation:

Since it takes an initial 4 minutes to set up the screen-printer, we can subtract 4 from 41 minutes to get the time used to print the shirts.

41 - 4 = 37

Since each shirt requires 1 minute of screen printing and there are 37 minutes, we can divide 37 by 1.

37 / 1 = 37

So there are 37 shirts in this batch. Hope this helps.

Answer: x = -1; y = -1

y = 3x + 2

y = -2x - 3

⇔ y = 3x + 2

   3x + 2 = -2x - 3

⇔ y = 3x + 2

    5x = -5

⇔ y = 3x + 2

    x = -1

⇔ y = -1

    x = -1

First choice, 25

Step-by-step explanation:

200 times 1/8 = 200/8 = 25

Answer:

(2, -7/2)

Step-by-step explanation:

According to the midpoint theorem;

M(X, Y) = [(ax1+bx2/a+b), ay1+by2/a+b ]

(x1, y1) and (x2, y2) are the coordinates

a:b is the given ratio

Given the following

Coordinate of the line segment (-8, 5) and (4, -3)

Ratio: 5:3

Get the X coordinate;

X = ax1 + bx2 / a+b

X = 5(-8) + 3(4)/5+3

X = -40+12/8

X = -28/8

X = -7/2

Get the Y coordinate

Y = ay1 + by2 / a+b

Y = 5(5) + 3(-3)/5+3

Y = 25-9/8

Y = 16/8

Y = 2

Hence the required coordinate is (2, -7/2)

Answer:

2816 rupees

Step-by-step explanation:

here , depth = 14 ft

diameter = 8 feet

so , radius = 4 ft

We will paint it in its C.S.A.

C.S.A. of a cylindrical well

= 2πrh

= 2×(22/7)× 4 × 14

= 352 ft²

so,

cost = rate per unit area × area

= (20/2.5)×352

= 8×352

= 2816

so,the cost of the painting will be 2816 rupees

Answer:

  see below

Step-by-step explanation:

I like a spreadsheet for doing repetitive calculations. The matchup is shown in the attachment.

The sale price is 100% - 35% = 65% = 0.65 times the regular price.

__

Here, you can also identify the matches by putting the prices in numerical order. The lowest regular price will correspond to the lowest sale price.

Answer:

P+Q+R+S+T=540. then substitute x for result in p

Step-by-step explanation:

i would work it out but im lazy sorry

In a pentagon, there are 540 degrees

First, find x.

Set up the equation

132 + (4x+2) + 128 + (5x -11) + (4x - 10) = 540

Combine like terms

260 +13x -19 = 540

241 + 13x = 540

solve

13x = 299

x = 23

Now plug x in to angle p (4x + 2)

4(23) + 2

92 + 2 = 94

Therefore angle P = 94 degrees

Answer:

98,635

Step-by-step explanation:

Step-by-step explanation:

y = x - 4 and y = 4x + 2

=> x - 4 = 4x + 2

=> 3x = -6

=> x = -2

y = x - 4 = (-2) - 4 = -6

The solutions are x = -2 and y = -6.

Answer:

x = -2

y = -6

Step-by-step explanation:

y = x - 4

y = 4x + 2

y = y

then:

x-4 = 4x+2

x - 4x = 4 + 2

-3x = 6

x = 6/-3

x = -2

y = x - 4

y = -2 - 4

y = -6

Answer:

[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

Step-by-step explanation:

Given the expression

[tex]a+\frac{2b}{3}=\frac{2}{c^9}[/tex]

subtract a from both sides

[tex]a+\frac{2b}{3}-a=\frac{2}{c^9}-a[/tex]

Simplify

[tex]\frac{2b}{3}=\frac{2}{c^9}-a[/tex]

Multiply both sides by 3

[tex]\frac{3\cdot \:2b}{3}=3\cdot \frac{2}{c^9}-3a[/tex]

Simplify

[tex]2b=\frac{6}{c^9}-3a[/tex]

Divide both sides by 2

[tex]\frac{2b}{2}=\frac{\frac{6}{c^9}}{2}-\frac{3a}{2}[/tex]

Simplify

[tex]b=\frac{6-3ac^9}{2c^9}[/tex]

Calculating 4/b

[tex]\frac{4}{b}=\frac{4}{\frac{6-3ac^9}{2c^9}}[/tex]       ∵ [tex]b=\frac{6-3ac^9}{2c^9}[/tex]

[tex]\frac{4}{b}\:=\frac{4\:\times \:\:2c^9}{6-3ac^9}[/tex]

[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

Therefore, we conclude that:

[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

Answer:

y = 5.064 - 0.010x

Here, in this question x = 33

y = 4.734 million views

In this question data is missing and I filled it out and calculated the questions accordingly. Please refer to the attachment for the data calculated.

Step-by-step explanation:

First of all, this question is incomplete. It lacks the data needed to calculate the required things.

So, I  figured out the question and I will try my best to solve the question at hand.

I have calculated the some data sheet in excel. Please refer to the attachment for that data.

let a be the salaries

b be the viewers

[tex]S_{aa}[/tex] = ∑[tex]a^{2}[/tex]  - [tex]\frac{ Summtion a^{2} }{n}[/tex]

[tex]S_{aa}[/tex] = 7522.8571

[tex]S_{bb}[/tex] = ∑[tex]b^{2}[/tex]  - [tex]\frac{ Summtion b^{2} }{n}[/tex]

[tex]S_{bb}[/tex] = 47.1943

[tex]S_{ab}[/tex] = ∑[tex]ab^{}[/tex]  - [tex]\frac{ Summtion a x Summation b^{} }{n}[/tex]

[tex]S_{ab}[/tex] = -76.8286

Now the slope of the required regression equation is:

Slope =  [tex]S_{ab}[/tex]/[tex]S_{aa}[/tex] = -76.8286/7522.8571 = -0.010

And the intercept of the required regression equation:

intercept = [tex]\frac{1}{n}[/tex] x (∑b - slope x ∑a) = 5.064

So, the regression equation will be:

y = intercept + slope x

y = 5.064 - 0.010x

Here, in this question x = 33

y = 5.064 - 0.010 (33)

y = 4.734 million views

Answer:

x = 9/2

Step-by-step explanation:

Answer:

x = [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

Given

5(2x + 1) = 50 ( divide both sides by 5 )

2x + 1 = 10 ( subtract 1 from both sides )

2x = 9 ( divide both sides by 2 )

x = [tex]\frac{9}{2}[/tex]

Answer: See explanation

Step-by-step explanation:

Here's the correct question:

Krystal is comparing two internet service plans. Plan 1 cost $34.99 per month. Plan 2 costs $ 134.97 every 3 months. If Krystal plans to stay with one service plan for 1 year which should she choose? how much will she save?

Cost of plan 1 per month = $34.99 per month. Therefore, the cost for the year would be:

= 12 × $34.99

= $419.88

Plan 2 cost $134.97 for 3 months. Therefore the cost for the year would be:

= 4 × $134.97

= $539.88

She would choose the first plan as it's cheapee. She would also save:

= $539.88 - $419.88

= $120

Step-by-step explanation:

Brian = 11.74 seconds

Luis = 11.69 seconds

Difference between their times :

11.74 - 11.69 = 0.05

Expressed as a fraction of a second :

0.05 / 1 = (0.05 * 100) / (1 * 100) = 5 /100 = 1/20
