Answer:

A

Step-by-step explanation:

The equation of line is y= -4x -23

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. 

The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows. In the coordinate plane, it describes the slope of the line.

Given:

We can take the coordinates from the given graph as (0, 3) and (2, -5)

Now, the slope = (-5 - 3)/ (2 - 0)

slope= -8/ 2

slope= -4

Now, using the point- slope form

(y - [tex]y_1[/tex]) = m(x - [tex]x_1[/tex])

(y- (-3))= -4( x- (-5))

y+3 = -4(x+5)

y+ 3= -4x - 20

y= -4x -23

Hence, the equation of line is y= -4x -23.

Step-by-step explanation:

f(x) = 2x - 7 - 3

~Combine like terms

f(x) = 2x - 10

When x = 2...

f(x) = 2(2) - 10

f(x) = 4 - 10

f(x) = -6

When x = 3...

f(x) = 2(3) - 10

f(x) = 6 - 10

f(x) = -4

When x = 4...

f(x) = 2(4) - 10

f(x) = 8 - 10

f(x) = -2

Answer:

Sample mean (xbar) = 40

Step-by-step explanation:

Given that :

Sample size (n) = 64

Population mean (μ) = 40

Standard deviation (σ) = 5

The sample mean is equal to the population mean according to the central limit theorem.

The sample standard deviation = standard error = ;

Standard Error = σ / √n

Standard Error = 5 / √64

Standard Error = 5 / 8

Standard Error = 0.625

Answer:

check the first two and the last one

Step-by-step explanation:

you use multiplying/dividing and adding/subtraction to get the answer

10x+45x-13 = 11(5x+6)

55x-13 = 11(5x+6) combine like terms

55x-13 = 55x+66 distribute the 11 to the 5x and 6

-13 = 66 cancel out equal terms on both sides

the statement is false meaning there is equation has no solution

Step-by-step explanation:

Why are you asking? Why isn't your friend?

The diagram assumes that the angle on the lower left of the triangle is a right angle. If it is not, then I don't think there is a way that this can be solved.

Tan(A) = opposite / adjacent

opposite = 7

Adjacent = 4

Tan(A) = 7/4 = 1.75

A = inverseTan (1.75)

A = 60.60 degrees

Answer:

-36

Step-by-step explanation:

Step-by-step-explanation

The first thing you would do is multiply both numbers inside the parenthesis by -3.

You would get -21 + (-15) or you could just wrtie -21 - 15, whichever is easier for you.

Then you'd simply add both -21 and -15 together, and you get -36. :D

Answer:

Mean = 0.45

Standard deviation = 0.04035

Step-by-step explanation:

This is actually a very simple problem.

The question gives us the report that 45% of the teenagers in the age bracket own smartphones.

P = mean = 45%

Therefore the mean is 0.45.

I will go ahead to help you calculate the standard deviation.

√p(1-p)/n

n = 152

P = 0.45

√0.45(1-0.45)/152

= √0.45(0.55)/152

= √0.2475/152

= √ 0.001628

= 0.04035

Answer:

11.025

Step-by-step explanation:

you have to add 2.45, 4.5 times. Or you can just multiply 2.45 by 4.5.

Answer:

84

Step-by-step explanation:

Answer:

x = 174 °

Step-by-step explanation:

All quadrilaterals have an interior angle sum of 360°. Therefore the 4 interior angles added together should equal  360°. The question already gave us three of the four angles.

74 + 66 + 46 + x = 360

              186 + x = 360

                        x = 174

Answer:

8.5

Step-by-step explanation:

-2(x-5)+3=-4

Step 1 distribute

−2+10+3=−4

Step 2 add the numbers

-2x+13=-4

Step 3 subtract 13 from both sides of the equation

−2-13+13=-4-13

Step 4 get ride of the two 13

-2x=-4-13

Step 5 subtract -4 subtract 13

-2x=-17

Step 6 divide -17 by -2

-2x/-17

Step 6 answer

Answer:

R=60

S=55

T=65

Step-by-step explanation:

[tex]\boldsymbol{m\angle R, m\angle S, m\angle T}[/tex] are equal to [tex]\boldsymbol{60^{\circ},55^{\circ},65^{\circ}}[/tex] respectively.

According to angle sum property of a triangle, sum of all angles of a triangle is equal to [tex]\boldsymbol{180^{\circ}}[/tex]

Let [tex]m\angle R=x[/tex]

As [tex]m\angle T[/tex] is [tex]5^{\circ}[/tex] more than [tex]m\angle R[/tex],

[tex]m\angle T=5^{\circ}+m\angle R[/tex]

[tex]\boldsymbol{m\angle R=m\angle T-5^{\circ}}[/tex]

Also,

[tex]m\angle S[/tex] is [tex]10^{\circ}[/tex] less than [tex]m\angle T[/tex],

[tex]\boldsymbol{m\angle S=m\angle T-10^{\circ}}[/tex]

So,

            [tex]\boldsymbol{m\angle R+m\angle S+m\angle T=180^{\circ}}[/tex]

[tex]m\angle T-5^{\circ}+m\angle T-10^{\circ}+m\angle T=180^{\circ}[/tex]

                       [tex]3m\angle T-5^{\circ}-10^{\circ}=180^{\circ}[/tex]

                                           [tex]m\angle T=\frac{195^{\circ}}{3}[/tex]

                                                    [tex]\boldsymbol{=65^{\circ}}[/tex]

[tex]m\angle R=65^{\circ}-5^{\circ}[/tex]

         [tex]\boldsymbol{=60^{\circ}}[/tex]

[tex]m\angle S=65^{\circ}-10^{\circ}[/tex]

        [tex]\boldsymbol{=55^{\circ}}[/tex]
