Step-by-step explanation:

Write in slope-intercept form,  y = m x +b .

Answer: m = -0.4

Step-by-step explanation: -7 - (-1) = -6 and 10 - (-5) =15, m=y/x so -6/15 equals -0.4.

answer:

640,000

step-by-step explanation:

to find the answer, we need to determine whether 41,267 is closer to 40,000 or 50,000.

looking at the numberline, we can conclude that the placement of 641,267 is closer to 640,000, not 650,000.

therefore, the answer is 640,000. (see image attached)

Here we want to order from least to greatest the following expressions:

7.12 = 7.121212...

√75

√45

We will find that the order is: √45 < 7.12 < √75

remember that:

√x = y

such that:

y*y = x

From this, is easy to see that:

√45 < √75

Now to see where 7.1212... enters, we need to compute:

(7.1212...)*(7.1212...) = (7 + 0.1212...)*(7 + 0.1212...)

                               = 7*7 + 2*7*0.121212... + 0.1212...*0.1212...

                               = 49 + 2*7*0.121212... + 0.1212...*0.1212... > 45

So we know for sure that:

7.12 > √45

And 8*8 = 64 < 75

then:

7.12 < 8 = √64 < √75

For transitivity, we have:

7.12< √75

Then the order, from least to greatest, is:

√45 < 7.12 < √75

  (c) the y-intercept is (0, 10); the x-intercept is (10, 0)

Step-by-step explanation:

(a) The graph tells you the wind chill is 6 °C when the wind speed is 4 m/s.

(c) The intercepts are marked on the graph. The y-intercept is (0, 10); the x-intercept is (10, 0). These represent the temperature when the wind speed is 0, and the wind speed when the temperature is 0, respectively.

Answer:

6x-6

Step-by-step explanation:

5x-(6-x)

First you distribute the negative to (6-x) which makes -6+x, then you just subtract that from 5x which makes 5x-6+x then you just simplify into 6x-6.

Answer:

y=-x+3

Step-by-step explanation:

The y-intercept is at 3 and you can see it has a slope of -1

The equation of line will be y = -x + 3.

It is given that in the graph, line is passing through some points at x-axis and y-axis.

We have to find the fully simplified intercept of the line.

What is the general equation of a line ?

The equation of a line is y = mx + c , where m is the slope of the line and c is a constant.

We have the x-intercept (3,0) and y-intercept (0,3) on the graph.

Slope of these line through these points will be ;

m = (y2-y1) / (x2-x1)

m= (3-0) / (0-3)

m= 3/-3

m= -1

Also , we will get the value of c = 3 .

The equation of line after putting the value of m and c will be ,

y = -x + 3

Thus, the equation of line is y = -x + 3

Answer:

D

Step-by-step explanation:

Domain of the function 3x + 2y = 8 are the possible set of x-values represented as {-2, 0, 2, 4}.

To know which graph represents the above given function, find the range values of the function by plugging in each value of x into the equation, to find y.

For x = -2,

3(-2) + 2y = 8

-6 + 2y = 8

2y = 8 + 6

2y = 14

y = 14/2

y = 7

(-2, 7)

For x = 0,

3(0) + 2y = 8

0 + 2y = 8

2y = 8

y = 8/2

y = 4

(0, 4)

For x = 2,

3(2) + 2y = 8

6 + 2y = 8

2y = 8 - 6

2y = 2

y = 2/2

y = 1

(2, 1)

For x = 4,

3(4) + 2y = 8

12 + 2y = 8

2y = 8 - 12

2y = -4

y = -4/2

y = -2

(4, -2)

The graph which shows the following set of coordinates pairs calculated above, ((-2, 7), (0, 4), (2, 1), (4, -2)), is the graph of the function 3x + 2y = 8.

Thus, the graph in option D the shows the following calculated coordinate pairs. Therefore, graph D is the answer.

Answer:

6 Gallons of Paint

Step-by-step explanation:

If you use a half gallon of paint to cover 84 square feet, how much could you paint with a full gallon? Lets figure it out:

[tex]\frac{1}{2} = 84[/tex]

multiply both sides by 2 so that the 1/2 gallon is now 1 gallon:

[tex]\frac{1}{2} * 2 = 84 * 2[/tex]

1 gallon = 168 square feet

now, how many gallons does it take to paint 932 square feet?

Divide 932 by 168:

[tex]\frac{932}{168} = 5.548[/tex]

Just like you cant buy 2.374 cheeseburgers, you cant buy 5.548 gallons of something so we round up and will have some paint left over once the job is done. So 6 gallons is the answer

The amount of gallons needed is 5.55gallons approximately

If Joel used a half-gallon of paint to cover 84 square feet of wall, this can be expressed using the equality sign as:

1/2 gallons = 84 square feet

In order to find the number of gallons for 932 square feet of wall to paint, we will write:

x = 932 square feet

Divide both expressions

1/2x = 84/932

2x = 932/84

2x = 11.09

x = 11.09/2

x = 5.55 gallons

This shows that the amount of gallons needed is 5.55gallons approximately

Step-by-step explanation:

-24+24=0

Answer:

x 1 = -3  

x2 = -3

y1 = 0

y2 = 5

The slope of that equation is infinite and the equation is a perfectly vertical line at x = -3.

So, the equation is x = -3.

Step-by-step explanation:

Given parameters:

The coordinates of points on the line;

  (x, y) = (-3,0) and (x, y) = (-3, 5)

Unknown;

The equation of the line = ?

The equation of a line is usually expressed in the form y = mx + c

  Where;

     y and x are the coordinates

      m is the slope

      c is the y-intercept

Now we need to first find the slope of the line.

    Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]  

       (x₁, y₁) = (-3,0) and (x₂, y₂) = (-3, 5)

Input the parameters and solve;

     Slope = [tex]\frac{5 - 0}{-3 -(-3)}[/tex]   = infinity

The line has an infinite slope.

The equation of the line is therefore x  = c

         x  = -3

Answer:

(1) The cost formula is: y = $19,050 + $12·x.

(2) The cost of moving materials if 340 moves are made is $23,130.

(3) 82.81% of the variability in moving cost is explained by the number of moves.

Step-by-step explanation:

The computer output for the regression analysis of 80 data points is as follows:

Intercept:  $19,050

Slope: 12

Coefficient of correlation: 0.91

Standard error:  $220

(1)

The general formula of regression equation is:

y = a + b·x

Here,

a = intercept

b = slope

The cost formula is:

y = $19,050 + $12·x

(2)

Predict the cost of moving materials if 340 moves are made as follows:

[tex]y = 19050 + 12\cdot x\\=19050+12\times 340\\=19050+4080\\=23130[/tex]

Thus, the cost of moving materials if 340 moves are made is $23,130.

(3)

The coefficient of determination R² specifies the percentage of the variance in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).

The coefficient of determination R² can be computed by squaring the correlation coefficient value.

[tex]R^{2}=(r)^{2}=(0.91)^{2}=0.8281[/tex]

Thus, 82.81% of the variability in moving cost is explained by the number of moves.

PERCENT CHANGE

The percentage change from 1.20 to 1.80 is 50 %

Our percent calculator uses this formula:

((y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)

((1.80 - 1.20) / 1.20) * 100 = 50 %
