Answer:

Step-by-step explanation:

-2x+3x=-21+6

or x=-15

Answer:

x=3

Step-by-step explanation:

-2x-6=3x-21

Add 21 to both sides of the equation

Add 2x to both sides of the equation

Divide each side by 5 to isolate x

Answer:

[tex]Rate = 15[/tex]

Step-by-step explanation:

Given

[tex]R(x) = 56 - 0.020x^2[/tex]

Required

Find the average change from​ 1,000 car seats to​ 1,050 car seats --- Missing information

This is calculated using:

[tex]Rate = \frac{R(b) - R(a)}{b-a}[/tex]

In this case:

[tex]a = 1000[/tex]

[tex]b = 1050[/tex]

Now, we have:

[tex]Rate = \frac{R(1050) - R(1000)}{1050-1000}[/tex]

[tex]Rate = \frac{R(1050) - R(1000)}{50}[/tex]

Calculating R(1050)

[tex]R(1050) = 56 *1050- 0.020*1050^2[/tex]

[tex]R(1050) = 58800-22050[/tex]

[tex]R(1050) = 36750[/tex]

Calculating R(1000)

[tex]R(1000) = 56 *1000- 0.020*1000^2[/tex]

[tex]R(1000) = 56000- 20000[/tex]

[tex]R(1000) = 36000[/tex]

So:

[tex]Rate = \frac{R(1050) - R(1000)}{50}[/tex]

[tex]Rate = \frac{750} {50}[/tex]

[tex]Rate = 15[/tex]

The average rate of change is 12

Question 3

C. [tex] y-9 =1/2(x-1)[/tex]

Question 4

D. [tex] y+5 =3(x+2)[/tex]

Step-by-step explanation:

Question 3:

Equation of line in point slope form is given as:

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

Plug m = 1/2, [tex] x_1 = 1, \:y_1 = 9 [/tex] in the above equation, we find:

[tex] y-9 =1/2(x-1)[/tex]

This is the required equation of the line.

Question 4:

Equation of line in point slope form is given as:

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

Plug m = 3, [tex] x_1 = - 2, \:y_1 = - 5[/tex] in the above equation, we find:

[tex] y-(-5) =3[x-(-2)][/tex]

[tex] y+5 =3(x+2)[/tex]

This is the required equation of the line.

Answer:

Cosine

Step-by-step explanation:

sine = soh=o/h

cos=cah=a/h

tangent=toa=o/a

If you look at right triangle the slanted line is the hypothese. it will always be. so thats h. the adjacent is the line connected the the angle you are looking for. and opposite is the line thats away from the angle.

Answer:

Removing pennies and dimes from the bag

Step-by-step explanation:

From the beginning, we have a 1 in 3 chance of drawing a quarter. If we were to add dimes and/or pennies to the bag, this would make us more likely to draw a dime or a penny, and less likely to draw a quarter. Proportionally, we want the most quarters in the bag to get the highest probability of drawing a quarter from the bag.

Answer:

-4

Step-by-step explanation:

Step-by-step explanation:

Amplitude of the sine function is 1.

So if its multiplied by -3, its amplitude is 3 (its always positive).

The midline of sin x is 0.

The midline of sin 2x is also 0.

The midline of -3*sin 2x is also 0.

So if you subtract this function by 5, then the new midline is -5.

Answer:

X = 3

Step-by-step explanation:

First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.

5x + 2 = 17

Then Solve For X

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide by 5

X = 3

Check your answer

5(3) +2 = 17

15 + 2 = 17

17 = 17

The lengths of sides of the parallelogram are 71 inches and 51 inches. Hence, option (C) is correct.

A unique variety of quadrilateral called parallelogram, a parallelogram has both pairs of its opposite sides parallel and equal.

Let sides of the parallelogram are a and b.

The perimeter of parallelogram  = 2(a+b)

Given that,

The perimeter of parallelogram = 244

implies that,

2(a+b) = 244

a+b = 122       (1)

Also, the difference of sides is 20 inches,

implies that,

a-b = 20       (2)

By solving equation (1) and (2),

a = 71 inches,

b = 51 inches.

The lengths of sides of the parallelogram are 71 inches and 51 inches.

Answer:

± 15 cm  

Step-by-step explanation:

In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.

In the second case, the uncertainty or error is also ± 1 cm.

Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm  

So, the total error in both cases is ± 15 cm.
