y=(2-X)/-2

Step-by-step explanation:

isolate y by itself

move x to the right side of equation

then divide your left side by -2 to isolate y

The slope intercept form of the given line equation is y = x/2 - 1.

The given equation of a line is x-2y=2.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Here, the equation can be written in slope intercept form as

x-2y = 2

2y = x-2

y = x/2 - 2/2

y = x/2 - 1

Therefore, the slope intercept form of the given line equation is y = x/2 - 1.

Answer:

A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.

Step-by-step explanation:

Given equation is 4x + 5y = 10

we have to convert it in slope intercept form

slope intercept form is given by y = mx + c

now seeing the slop intercept form ,

we can say that

we have to isolate y , for that we have to remove 4x from

4x + 5y = 10 from RHS of the equation

to do that we have to subtract 4x from both side as shown below

4x + 5y - 4x = 10 - 4x

this step is called  Subtraction Property of Equality to subtract 4x from both sides of the equation

and hence option A is the correct choice

Answer:

A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.

Step-by-step explanation:

Nature's Best wants to combine nuts they sell for $3.60 a pound with dried fruit they sell for $2.40 a pound to create a trail mix. How much of each snack should they use to make 10 pounds of trail mix that would sell for $3.30 a pound?

--------------

Let amt. of nuts be "x" lbs ; value is 3.60x dollars

-------------

Amt of fruit is "10-x" lbs ; value is 2.4(10-x) = 24-2.4x dollars

----------------------

Amt of mix is 10 lbs ; value is 3.3*10= 33 dollars

------------------------

EQUATION:

value + value = 33 dollars

3.6x + 24-2.4x = 33

1.2x = 9

x = 7.5 lbs (amt of nuts in the mix)

10-x = 2.5 lbs (amt of fruit in the mix)

Answer:

4,8,14

Step-by-step explanation:

The three numbers are x = 4, y = 8 and z = 14 respectively.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the sum of three numbers as 26. The second number is twice the first and the third number is 6 more than the second.

Assume that the first number is x.

Then, the second number will be equal to 2x

The third number would be equal to (2x + 6)

Now, theirs sum is equal to 26. Therefore, we can write -

x + 2x + 2x + 6 = 26

5x + 6 = 26

5x = 26 - 6

5x = 20

x = 4

Then,

the second number (y) would be equal to (2 x 4) = 8

the third number (z) would be equal to (2 x 4 + 6) = 14

Therefore, the three numbers are x = 4, y = 8 and z = 14 respectively.

Eligible voters are who belong to the country where the elections are held and have the right age for voting, they have the right to vote according to the government rules and regulations.

According to the survey, the eligible voters' participation in the election is only 60% of the total voters.

Voting is the right of every individual who belongs to the country and chooses the perfect government for their country. It is bad for the individual who is not voting for the country and not showing interest in politics.

Answer:

y=8x+36

Step-by-step explanation:

Use y=mx+b.  First find m, the slope.  

To do that, use y2-y1/x2-x1.  Use any two point combinations from the table.  You can use (6,84) and (12,132).  

Y2 would be 132 and Y1 would be 84, and X2 would be 12 while X1 is 6.  Just look at the pointss.  For example, Y2 is 132 because (12,132).  132 is in y's spot.  Same goes for x.

Now that we got y2, y1, x2, and x1, we can plug it into the formula and solve.

y2-y1/x2-x1= 132-84/12-6= 48/6= 8

This means the slope is 8.  Now, we need to find the y intercept.

Use y=mx+b again and use any pair of points.  I'm going to use (6,84).

y=mx+b.  Plug in the slope, which is 8.

y=8x+b

y=8x+b.  Plug in the y.  The y variable is 84 so plug that in.

84=8x+b.  Same for the x.  The x variable is 6 so plug that in as well.

84=8(6)+b.  Now simplify it.

84=48+b.  You want to isolate b to find the y intercept so move the 48 to the left side.  

It's now 84-48=b.  The 48 because negative because whenever you move a number to the other side, it switches its sign.

Solve.

84-48=b

36=b or b=36.  So the y intercept is 36.

We now have our slope and the y intercept.  

Slope: 8

Y intercept: 36

We can plug that into y=mx+b a final time.

y=8x+36

The equation of the linear model is y = 8x + 36

The standard form of a linear equation is given by:

y = mx + b

Where y is a dependent variable, x is an independent variable, m is the slope of the line (the rate of change), b is the y intercept (that is the initial value of y).

Let x represent the number of T-shirts and y represent the cost

Therefore we can use any two points to determine the linear equation to represent the model of the line in the form (x, y).

Using the points (6, 84) and  (24, 228). The equation is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-84=\frac{228-84}{24-6} (x-6)\\\\y-84=8x-48\\\\y=8x+36[/tex]

The equation of the linear model is y = 8x + 36

Which equals

Answer:

Step-by-step explanation:

147 maintained 65% attendance for the 1st 4 weeks

the goal is 70% on the next 4 weeks

ratio and proportion:

147 students =         x        

       65                     70      

65 (x) = 147 (70)

x = 10,290  

         65

x ≈ 159 students

therefore, the number of students would need to attend

                 daily for the next 4 weeks is

                 = 159 - 147

We're looking for two numbers, where

1. We can easily find the square root of the first number

2. When we multiply that number by the second, we get 108.

We can experiment with numbers for 108. We know that [tex]36 \cdot 3 = 108[/tex], so we can form this statement now.

[tex]\sqrt{108} = \sqrt{36 \cdot 3}[/tex]

Answer:

  d.  z = -48

Step-by-step explanation:

When j ║ k, corresponding angles are congruent, so ...

  x = 4z +3y

  57 = y + z

and the same-side interior angles are supplementary:

  57 +x = 180   ⇒   x = 123

__

This lets us write two equations in y and z:

  3y +4z = 123

  y +z = 57

Using the second equation to write an expression for y, we have ...

  y = 57 -z

Substituting this into the first equation gives ...

  3(57 -z) +4z = 123

  z +171 = 123

  z = -48 . . . . . . . subtract 171

The value of z that makes j║k is -48.

___

The corresponding value of y is 105.
