Points on graphs choose all items which are true

Points On Graphs Choose All Items Which Are True

Answers

Answer 1

Answer:

the 3rd 4th and 5th answers are true

Step-by-step explanation:

just substitute the points into the equations.

first equation, substitute the points 2,8 into the equation.  2 + 2(8) = 20.

2 + 16 = 20

18 = 20 is not a true statement.

second equation, substitute the points -1,5 into the equation.  -1 + 2(5) = 10.

-1 + 10 = 10

9 = 10 is not a true statement.

third equation, substitute the points 7,7 into the equation. 2(7) - 7 = 7.

14 - 7 = 7

7 = 7 is a true statement.

fourth equation, substitute the points 7,-7 into the equation. 3(7) + -7 = 14.

21 + -7 = 14

14 = 14 is a true statement.

fifth equation, substitute the points 1, 1 into the equation. 2(1) + 6(1)  = 8.

2 + 6  = 8

8 = 8 is a true statement.

Write a linear function with the values f(0) = 5 and f(-3) = 6

Answers

Answer:

You are given two points, (0,6) and (3,-3), so use the two-point formula for the equation of a line:

y - y1 = ( (y2 - y1) / (x2 - x1) ) (x - x1)

y - 6 = ( -9 / 3 ) (x - 0)

y - 6 = -3x

y = -3x + 6 This is: y = mx+b

Step-by-step explanation:

hope this will help you..

The linear function with the values f(0) = 5 and f(-3) = 6 is [tex]y=\frac{-1}{3}x+5[/tex]

The given functions are:

f(0)  =  5

f(-3)  =  6

That is, x₁ = 0,  y₁ = 5, x₂ = -3, y₂ = 6

The slope of the linear function is calculated as:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{6-5}{-3-0} \\\\m=\frac{-1}{3}[/tex]

The equation of a line is given as:

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

[tex]y-5=\frac{-1}{3}(x-0)\\\\y-5= \frac{-1}{3}x\\\\y=\frac{-1}{3}x+5[/tex]

I need help its about. Inequalities

Answers

Answer:

(-1, 3), (-5, -5), and (1, 2)

Step-by-step explanation:

To make this easier to solve, simplify the inequality:

12x - 3y < 12

= -3y < -12x + 12 (subtract 12x)

= 3y > 12x - 12 (multiply by -1, switch the inequality because it was a multiplication by a negative number)

= y > 4x - 4 (divide by 3)

Now, just go through each point and see if they are correct after you plug them into the inequality and solve:

(-1, 3): 3 > -8? yes

(-5, -5): -5 > -24? yes

(0, -4): -4 > -4? no

(1, 2): 2 > 0? yes

(4, 4): 4 > 12? no

(3, 8): 8 > 8? no

In conclusion, the points (-1, 3), (-5, -5), and (1, 2) fit the inequality.

The radius of the base of a cylinder is decreasing at a rate of 9 millimeters per hour and the height of the cylinder is increasing at a rate of 2 millimeters per hour. At a certain instant, the base radius is 8 millimeters and the height is 3 millimeters. What is the rate of change of the surface area of the cylinder at that instant in square millimeters per hour?
a) 310pi
b) 155pi
c) -155pi
d) -310pi

Answers

Answer:

Answer: d) -310pi

Step-by-step explanation:

Instantaneous Rate of Change

Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.

The surface area of a cylinder of radius r and height h is:

[tex]A=2\pi r^2+2\pi r h[/tex]

We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:

The radius is r=8 mm

The height is h=3 mm

The radius changes at r'=-9 mm/hr

The height changes at h'=+2 mm/hr

Find the derivative of A with respect to time:

[tex]A'=2\pi (r^2)'+2\pi (r h)'[/tex]

[tex]A'=2\pi 2rr'+2\pi (r' h+rh')[/tex]

Substituting the values:

[tex]A'=2\pi 2(8)(-9)+2\pi ((-9) (3)+(8)(2))[/tex]

Calculating:

[tex]A'=-288\pi +2\pi (-27+16)[/tex]

[tex]A'=-288\pi +2\pi (-11)[/tex]

[tex]A'=-288\pi -22\pi[/tex]

[tex]A'=-310\pi[/tex]

Answer: d) -310pi

Ms.Liu has $60 to buy candy and soda at the movies theater for her family. Candy cost $6 per box and soda cost $4 per cup .Write an algebraic expression that can be used to find the amount of money mr.Liu will have left if she buys a number of boxes of candy (c)and cups of soda (s).

Answers

Given :

Ms. Liu has $60 to buy candy and soda at the movies theatre for her family.

Candy cost $6 per box and soda cost $4 per cup.

To Find :

Write an algebraic expression that can be used to find the amount of money ms. Liu will have left if she buys a number of boxes of candy (c) and cups of soda (s).

Solution :

Let, number of candy and soda are c and s.

So, their price is :

Price = 6c + 4s

Amount left = 60 - ( 6c + 4s )

Amount left = 60 - 6c -4s

Hence, this is the required solution.

Sara wants to buy some billboards. The company she is buying the billboards from sells: billboards with 4 lines for $20 and billboards with 6 lines for $30. If Sara buys 7 billboards for 140, what type of billboard did she buy? Show the steps!!!!

Answers

Answer: Sara bought billboards with 4 lines for $20 (the quantity is 7)

We have to take the total cost (t) and divide that buy the 6 lines billboards and the 4 line billboards.

We know one 6 line billboard = $30We know one 4 line billboard = $20

So, let's divide $140 by 20 and 30 (the cost for each type of billboard).

$140 ÷ 30 = 4.6

This can not be the answer because Sara bought 7 billboards, not 4.6

$140 ÷ 20 = 7

So, the answer is Sara bought billboards with 4 lines for $20.

Hope this helps you!

Answer: billboards with 4 lines for $20 (7 count)

140 divided by 30 is not 20.

140 divided by 20 is 7.

The answer to the question = 7

Answer:

Let's identify what we know and what we are looking for. To start off, the question states that there is a flat rate of 500. This is the y intercept, because you start off with 500. It also states that it charges a fee of 50 per hour, which is your slope. So what we have now is y=50x+500. We know that A is asking how much it will be for 20 hours. We simply plug 20 into x, so we do y=50(20)+500 which gives 1500. For C, we repeat the same step and just plug in 50.

a). The dependent variable is,

   Amount of money in the bank account.

    The independent variable is,

   Number of hours of babysitting

b). x       0        1         2         3        4

If S represents the number of seventh grade students who came to the dance and g represents the number of eighth grade students at the dance, which expression BEST represents the total money collected for attending the dance.

a. 6.25s + g
b. 6.25(s + g)
c. 13.50(s + g)
d. 6.25(s + g)

Answers

The answer would be b: 6.25(s+g)

you can already cancel out c., as there’s no way it could be 13.50

since it says it’s $6.25 dollars for all grades and you would be trying to find both 7th and 8th graders, you would need to multiply both variables by the amount they need to pay. in this case, $6.25.
