Which is the equation of the trend line that is shown?

y=1/7x + 4/7

y = 1/7x + 16/7

y = 4/7x + 1/7

y = 4/7x - 1/7

Answer:

x = 35

Step-by-step explanation:

I solved for x by simplifying both sides of the equation, then isolating the variable.

Hope this helps:)

Answer:

Step 1: Simplify both sides of the equation.

x−12=−32+55

x+−12=−32+55

x−12=(−32+55)(Combine Like Terms)

x−12=23

x−12=23

Step 2: Add 12 to both sides.

x−12+12=23+12

x=35

Answer:

x=35

Answer:

32, 47, x+17, 43

Step-by-step explanation:

Answer:

x=5

Step-by-step explanation:

2x−7=−3x+18

Step 1: Add 3x to both sides.

2x−7+3x=−3x+18+3x

5x−7=18

Step 2: Add 7 to both sides.

5x−7+7=18+7

5x=25

Step 3: Divide both sides by 5.

5x

5

=

25

5

x=5

Answer:

x = 5

Step-by-step explanation:

2x - 7 = -3x + 18

2x - 7 + 7 = -3x  + 18 + 7

2x = -3x + 25

2x + 3x = -3x + 25 + 3x

5x = 25

x = 5

D) -3

because the number should be less than -2 and greater than -6

so here only -3 satisfies the condition

Answer:

170cm

Step-by-step explanation:

Given data

perimeter of 600 cm

let the Length be x

L=x

W= x-40

P=2L+2W

600=2(x)+2(x-40)

600=2x+2x-80

600= 4x-80

600+80= 4x

680= 4x

divide both sides by 4

x= 680/4

x=170

Hence the length is 170cm

Answer:

Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2).

Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).

Step-by-step explanation:

The variables have to be the same in both equations in the 2 × 2 system.

All of this should be included

Answer:

1/2 of the original pizza is left over

Step-by-step explanation:

When solving this question, divide 8 by 4. That will give you one fourth of the pizza. Multiply that by three, and you will get 6. Then divide 6 by 3, to get 2 as one third of 6.

Subtract 2 from 6 to get 4

Step-by-step explanation:  Chemical signal is the type of communication which coordinates actions between neighboring cells . This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.

Answer:

Step-by-step explanation:

2 real roots and 2 complex

Following are the solution to the given polynomial equation:

Given:

Polynomial equation: [tex]\bold{n(x) = 3x^4 - 9x^3 + x^2 -3x}[/tex]

Factor: [tex]\bold{(x -3)}[/tex]

To find:

A number of roots for the polynomial n(x).

Solution:

Polynomial equation: [tex]\bold{n(x) = 3x^4 - 9x^3 + x^2 -3x}[/tex]

[tex]\to \bold{(x -3)=0}\\\\\to \bold{x =3}\\\\[/tex]

Putting the of x into the given Polynomial function:

[tex]\to \bold{n(3) = 3(3)^4 - 9(3)^3 + (3)^2 -3(3)}\\\\\to \bold{n(3) = 3\times 81 - 9\times 27 + 9 -3 \times 3}\\\\\to \bold{n(3) = 243- 243 + 9 -9}\\\\\to \bold{n(3) = 0}\\\\[/tex]

Let divide the Polynomial function by the factor:

[tex]\to \bold{\frac{3x^4 - 9x^3 + x^2 - 3x}{x-3}}\\\\\to \bold{\frac{ x(3x^3 - 9x^2 + x - 3)}{x-3}}\\\\\to \bold{\frac{ x(3x^2(x - 3)+1(x - 3))}{x-3}}\\\\\to \bold{\frac{ x(x - 3) (3x^2+1)}{x-3}}\\\\\to \bold{x(3x^2+1)}\\\\[/tex]

So, the factors are [tex]\bold{x, (x-3),\ and \ (3x^2+1)}[/tex].

Calculation of the roots:

[tex]\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x-3=0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3x^2+1 =0}\\\\\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x=3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3x^2 = -1}\\\\\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x=3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x^2 = -\frac{1}{3}}\\\\\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x=3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x^2 = (- \sqrt{\frac{1}{3}})^2}\\\\[/tex]

Therefore the final answer is "Option A".

Answer:

Here's the picture + somewhat process? (hard to explain, please lmk if it's wrong and i'll fix it!!)

Given:

Mason misses 25% of the free throws he attempts in a season.

Number of missed free throws = 52

To find:

The total number of free throws.

Solution:

Let x be the total number of free throws.

Mason misses 25% of the free throws he attempts in a season.

Number of missed throws = 25% of x

Number of missed free throws = 52

Now,

[tex]\dfrac{25}{100}x=52[/tex]

[tex]\dfrac{1}{4}x=52[/tex]

Multiply both sides by 4.

[tex]x=52\times 4[/tex]

[tex]x=208[/tex]

Therefore, the total number of free throws is 208.

Answer:

£60 : £24

Step-by-step explanation:

Let's put the ratio into one number.

5 + 2 = 7

There are 7 parts in our ratio, so let's find one part.

£84 ÷ 7 = £12

Going back to the original ratio, we can multiply one part by 5 and 2.

£12 × 5 = £60

£12 × 2 = £24

And it all adds back together to make £84.

£60 + £24 = £84

x = 8

Step-by-step explanation:

Since the sum of the angles in a straight line is 180, and we know that angle four is 120, to find angle 3, simply subtract 120 from 180.

Angle 3 is 180-120 = 60

Since we know 2 angles already, we have: 60 + 95 = 155. Now subtract that from 180.

Angle 1 is 180-155 = 25
