please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Rasheem runs 1/5 miles in 2 minutes.
What is Rasheem’s speed in miles per minute?
Explain if you can. :)
Answer:
10 minutes per mile
Step-by-step explanation:
Rasheem runs 1/5 miles in 2 minutes. What you need to do is find how many minutes it takes for 1 whole mile. To do this, you have to first see what you multiply to 1/5 to get to 1. As you know, you do 1/5 x 5/1 (or 5) to get to one. Since you did that 1/5, you also need to multiply 2 x 5, which is 10. This gives you the answer that Rasheem was running 10 minutes per mile.
Hope it helped! :)

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
Answer:
yes if each machine makes popcorn for 10 minutes, there be enough popcorn for eight 9-ounce bags
Step-by-step explanation:
yes because 12.74 x 3.3 = 42.075 and 18 x 2.5 = 45 and when you add those together you get 87. Also 8 9-ounce bags = 72 and that is less then what you have.
Answer:
Yes there will be enough popcorn for eight 9-ounce bags.
Step-by-step explanation:
" eight 9-ounce bags"
Basically
"72 ounces"
"12.75 ounces of popcorn in 3 minutes"
Basically
We need to find out how much popcorn we can make in "One Minute"
12.75÷3=4.25
Now we need to find out how much it can make in "Ten Minutes"
4.25×10=42.5
"18 ounces of popcorn in 4 minutes."
Basically:
We wanna find out how much it can make in "One Minute"
18÷4=4.5
"makes popcorn for 10 minutes"
Basically:
We need to find out how much popcorn it can make in "Ten Minutes"
4.5×10=45
Add (45) and (42.5)
45+42.5=87.5
So yes,there will be enough popcorn for eight 9-ounce bangs due to the fact A and B makes (87.5) ounces of popcorn and thats greater than (72) ounces.

Answer:
The 16 cases will fit the box as shown.
Step-by-step explanation:
One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.
Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.
1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.
2) The horizontal length of each case is 14.2 cm. Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.
3) The vertical measurement of each case is 19.3 cm. The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.
All indications are that the 16 cases will fit comfortably inside the box.
Answer:
16 discs capacity of the cuboid.
Step-by-step explanation:.
for simplicity...
i would just divide 26cm to 1.6cm = 16 .25
therefore, 16 discs capacity of the cuboid.

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night, the theater makes $1,512 from popcorn sales and $1,584 from nacho sales. If on the next night the employees sell $1,848 of popcorn, how much is earned from nachos?
Answer:
Using proportions, it is found that $1,225 is earned from nachos.
This question is solved by proportions, using a rule of three.
The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The rule of three is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:
$1,225 is earned from nachos.
Buddy the Elf has already eaten spaghetti with syrup that was 1300 calories. If he eats candy canes that are 80 calories each, write an equation to represent the total calories (y) after eating x candy canes.

A toy company is building dollhouse furniture. A rectangular door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door on a scale drawing that uses the scale 3:5?
33 cm
20 cm
14 cm
12 cm
I will give brainiest and thanks if answer is right.
Answer:
12 cm
Step-by-step explanation:
In the picture
Answer: 33cm
Step-by-step explanation:
To find the perimeter of the door on the scale drawing, we first need to determine the dimensions of the door on the scale drawing.
The scale given is 3:5, which means that every 3 centimeters in real life corresponds to 5 centimeters on the scale drawing.
To find the height of the door on the scale drawing, we multiply the real-life height of 7 centimeters by the scale factor:
7 cm * (5 cm/3 cm) = 35/3 cm ≈ 11.67 cm
To find the width of the door on the scale drawing, we multiply the real-life width of 3 centimeters by the scale factor:
3 cm * (5 cm/3 cm) = 5 cm
Now that we have the dimensions of the door on the scale drawing (height: 11.67 cm and width: 5 cm), we can calculate the perimeter.
The perimeter of a rectangle is found by adding up all the sides. In this case, we have two sides of length 11.67 cm (height) and two sides of length 5 cm (width).
Perimeter = 2 * (11.67 cm) + 2 * (5 cm) = 23.34 cm + 10 cm = 33.34 cm
Therefore, the perimeter of the door on the scale drawing is approximately 33.34 cm.
Since the answer choices are given in whole numbers, the closest option to the calculated perimeter is 33 cm.
The diagram shows a circle inside a square.

16 cm
Work out the area of the circle.

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

There is/are term(s).
Answer:
There are 4 terms in the expression 200+(5∗3)−30+3. The terms are 200, 5×3, −30, and 3.
A term is a single number or variable, or a product or quotient of numbers and variables. In this expression, each of the numbers 200, 5, 3, and −30 is a term. The product 5×3 is also a term.
The terms are separated by addition and subtraction signs. The expression is evaluated by performing the operations in parentheses first, then the multiplication and division, and finally the addition and subtraction.
Step-by-step explanation:
At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
\(m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2\)
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50
