A line passes through the points (-4,-1) and (4,3) a second line passes through the points (-2,-2) and (2,6) at what point do the two lines intersect

Answer:

A.

Step-by-step explanation:

The Y-intercept is 3 so C and D are automatically are wrong because their Y intercept is 2.

The slope is 2x because you count the points that the line goes through.

For example: From (-1,1) count up and right until you get another point,

count using [tex]\frac{Rise}{Run}[/tex] the rise of this equation is 2 and the run is 1 so [tex]\frac{2}{1} = 2\\[/tex]

Rise = Vertical

Run = Horizontal

Because the slope is increasing the slope is positive meaning B is incorrect because it's slope is negative.

Hope this was clear and helped you out!

The equation that matches the graph is y = -2x + 3

A linear equation is in the form:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept

The line passes through the point (0, 3) and (-1.5, 0). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{0-3}{1.5-0} (x-0)\\\\y=-2x+3[/tex]

The equation that matches the graph is y = -2x + 3

[tex]x>-6[/tex]

Step-by-step explanation:

[tex]-4x-12<12[/tex]

[tex]-4x-12+12<12+12[/tex] (Add [tex]12[/tex] to both sides of the inequality to isolate [tex]x[/tex])

[tex]-4x<24[/tex] (Simplify)

[tex]\frac{-4x}{-4}<\frac{24}{-4}[/tex] (Divide both sides of the inequality by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)

r = 19

Answer:

r=1/20

Step-by-step explanation:

-5=-4-20r    (+4 both sides)

Answer:

The mean is 47

Step-by-step explanation:

First, you want to add up all of the numbers.

47 + 25 + 43 + 33 = 148

Now, you want to divide what you got by how many numbers there are.

148/4 = 37

The mean is 47

   Mean of the terms given in the data set as {47, 25, 43, 33} (four terms) will be 37.

          Mean = [tex]\frac{\text{Total of the terms in a data set}}{\text{Numbers of the terms}}[/tex]

Total of the terms given in the the data set = 47 + 25 + 43 + 33

                                                                        = 148

Number of terms in the data set = 4

Substitute these values in the expression of the mean,

Mean = [tex]\frac{148}{4}[/tex]

          = 37

      Therefore, mean of the data set given in the question is 37.

Can u plz mark me branliest plz.

Answer:

p = 50

Step-by-step explanation:

[tex]\frac{1}{2} *p+75=100\\[/tex]

Combine like terms into a single fraction:

[tex]\frac{1}{2} p+75=100[/tex]

[tex]\frac{1p}{2} +75=100[/tex]

Multiply by 1:

[tex]\frac{1p}{2}+75=100[/tex]

[tex]\frac{p}{2} +75=100[/tex]

Subtract 75 from both sides of the equation:

[tex]\frac{p}{2} +75=100[/tex]

[tex]\frac{p}{2} +75-75=100-75[/tex]

Simplify:

Subtract the numbers:

[tex]\frac{p}{2} +75-75=100-75[/tex]

[tex]\frac{p}{2} =100-75[/tex]

Subtract the numbers:

[tex]\frac{p}{2} =100-75[/tex]

[tex]\frac{p}{2} =25[/tex]

Multiply all terms by the same value to eliminate fraction denominators:

[tex]\frac{p}{2} =25[/tex]

[tex]2*\frac{p}{2} =2*25[/tex]

Simplify:

[tex]2*\frac{p}{2} =2*25[/tex]

[tex]p=2*25[/tex]

Multiply the numbers:

Answer:

It would be the fourth choice.

Step-by-step explanation:

To get ABCDE to A'B'C'D'E', you need to reflect the shape across line M. Then to go from A'B'C'D'E' to A''B''C''D''E'', you need to rotate about point C 180⁰.

It was first reflected across the x axis which would be line m. And since point c is the same place for the two bottom images , after the reflection it was rotated on point c.

Answer:

8

Step-by-step explanation:

x = nickles

y = dimes

0.05x + 0.10y = 1.70

x + y = 21

y = 21 - x

0.05x + 0.10 (21 - x) = 1.70

0.05x - 0.10x + 2.10 = 1.70

-0.05x + 2.10 = 1.70

-0.05x = -0.40

x = 8
