Answer:

option A is correct. this graph is a linear function

Step-by-step explanation:

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept

Answer:

C.

Answer:

$3000

Step-by-step explanation:

If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.

To find the total tuition, divide 1800 by 0.6:

1800/0.6

= 3000

So, their tuition was $3000

Answer:

m = 55t

t = m/55

Step-by-step explanation:

According to the formula for calculating speed expressed as;

Speed = distance/time

Given;

Distance = 55mph

required:

distance as a function of t

time as a function of distance m

If distance is m and time is t

From the formula;

55 = m/t

m = 55t

Hence the equation to solve for miles m is m = 55t

To get t, we will cross multiply from 55 = m/t;

55t = m

Divide both sides by 55

55t/55 = m/55

t = m/55

Hence the equation to solve for time in hours is t = m/55

Answer:

a.0.045km

d.4500cm

e.45000mm

Step-by-step explanation:

45meters is equivalent to 0.045km,4500cm,45000mm

Therefore the right answers are

a.0.045km

d.4500cm

e.45000mm

To determine which measurements are equivalent to 45 meters, we need to convert the given options to meters and compare them to 45 meters is 0.045 kilometers Therefore the correct option is A,B,D,E.

a. 0.045 kilometers: To convert kilometers to meters, we multiply by 1000. So, 0.045 kilometers is equal to 0.045 x 1000 = 45 meters. b. 0.45 kilometers: Similarly, 0.45 kilometers is equal to 0.45 x 1000 = 450 meters. c. 450 centimeters: To convert centimeters to meters, we divide by 100. So, 450 centimeters is equal to 450 / 100 = 4.5 meters.

d. 4,500 centimeters: Again, 4,500 centimeters is equal to 4,500 / 100 = 45 meters. e. 45,000 millimeters: To converted millimeters to meters, we divide by 1000. So, 45,000 millimeters is equal to 45,000 / 1000 = 45 meters.

Therefore, the measurements that are equivalent to 45 meters are a. 0.045 kilometers, b. 0.45 kilometers, d. 4,500 centimeters, and e. 45,000 millimeters. These measurements all represent the same length as 45 meters.

Hence the correct option is A,B,D,E.

Answer:

m = -8

b = 0

Step-by-step explanation:

In slope intercept form [ y = mx + b ], m = slope and b = y-intercept.

We aren't given a b value, but we are given a m value which is -8.

Answer:

y = 9x/5 + 50

Step-by-step explanation:

We are represent the information as coordinate (x,y)

If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)

Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;

(150, 320)

Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope;

m = y2-y1/x2-x1

m = 320-230/150-100

m = 90/50

m = 9/5

Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c

230 = 9/5(100)+c

230 = 9(20)+c

230 = 180 + c

c = 230-180

c = 50

Get the required equation

y = mx+c

y = 9/5 x + 50

Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

Answer:

y = 1x - 1

Step-by-step explanation:

[tex]\frac{y2-y1}{x2-x1}\\\frac{1-(-4)}{2-(-3)}\\\frac{1+4}{2+3}\\\frac{5}{5}=1\\y=1x+b\\1=1(2)+b\\1 = 2 + b\\-1 = b\\y = 1x-1[/tex]

Answer:

B

Step-by-step explanation:

The sum spent has to be either equal to or less than 40. So r many rides, each of them being 1.50, plus 10 dollars has to equal to less or equal to 40 dollars.

Answer:

The answer is B

The greatest number of rides Daniel can go on is 20.

Step-by-step explanation:

Total: The same or less than 40

Fair Admission: 10

ride: 1.50x

40 ≤ 10 + 1.5r

To solve:

40 ≤ 10 + 1.5r

40 - 10 ≤ 10 + 1.5r - 10

30 ≤ 1.5r

30 ÷ 1.5 ≤ 1.5r ÷ 1.5

20 ≤ r

The greatest number of rides Daniel can go on is 20.

Answer:

D: 113.04

Step-by-step explanation:

Volume cone formula: V=πr^2h/3

V = π(6)^2 3/3

V = 113.1

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer:

113.04 cubic inches

Step-by-step explanation:

First lets identify the equation to find the volume of a cone.

V= [tex]\pi[/tex] r^2 h/3

Next we'll plug in height and radius

h = 3

r = 6

V = [tex]\pi[/tex] 6^2 * 3/3

V = [tex]\pi[/tex] 36 * 3/3

V = [tex]\pi[/tex] 36 * 1

V = [tex]\pi[/tex] 36

V = 36[tex]\pi[/tex]

Now we'll use 3.14 for [tex]\pi[/tex] and times it by the 36

V = 36[tex]\pi[/tex]

V = 113.04

V= 113.04 cubic inches
