Will mark brainliest please help me Explain step by step how to find the equation of a line that goes through the points ( 7, 2 ), and ( 0, 4 ). Essay
Answer:
Step-by-step explanation:
Put the ordered pairs into the slope formula x=y2-y1/x2-x1 then you will get your slope of the line. once you have your slope pick an ordered pair and put it in point slope y-y1=m(x-x1) distribute and you will get your answer.
formula of a linear equasion:
y=mx+b
m=slope of the formula
to find m:
[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
plug in: [tex]\frac{4-2}{0-7} =\frac{2}{-7}[/tex]
m= [tex]-\frac{2}{7}[/tex]
y=[tex]-\frac{2}{7}[/tex]x+b
b is the y intercept
plug in to find b:
[tex]2=7(-\frac{2}{7} )+b\\2=-2+b\\4=b[/tex]
∴ [tex]y=-\frac{2}{7} x+4[/tex]

Decide whether each simulation fits the situation it is paired with.
Liza wants to give her brother a backpack
as a gift.She flips a coin to decide whether
to buy it online or at a local store.
Stephen needs to decide which country
to write about for his term paper: France,
Spain, or Germany. He uses a random
number generator with the numbers
1 through 5. The numbers 1 and 3 stand
for France, 2 and 4 for Spain, and 5 for
Germany.
Lloyd can't decide which cabinet hardware
to use in his kitchen: brass, nickel,
or chrome. He makes his choice by

Jessica is taking part in a fruit-carving
competition. To decide whether to carve
apples, pumpkins, or watermelons, she
spins a spinner with four equal sections
—one for apples, one for pumpkins,
and two for watermelons.
simulation fits the situation or simulation does not fit the situation
Answer:
Simulations That Fits Situation- Liza Wants To Give Her Brother A Backpack/ Lloyd Cant Decide Which Cabinet Hardware.
Simulations That Dont Fit The Situation- Stephen Needs To Decide Which Country/Jessica Is Taking Part In A Fruit Carving Competition.
Liza's simulation fits the situation since a coin flip is a common way to randomly choose between two options.
What is simulation?A simulation in statistics is a method of simulating real-world events or processes using a computer program or physical apparatus.
Liza's simulation fits the situation because a coin flip is a common way to choose between two options at random.
Stephen's simulation fits the situation because he uses a random number generator with different numbers assigned to each country, which is a fair way to choose between three options at random.
Jessica's simulation does not fit the situation because the spinner has two sections for watermelons, increasing the likelihood of selecting watermelons over apples or pumpkins.
Therefore, spinner is not a fair way to randomly choose between three options in this situation. A better simulation would be to assign equal probabilities to each option.

Answer:
60 ounces
Step-by-step explanation:
18/3=6
6x10=60
Answer:
60 ounces
Step-by-step explanation:

A circle has a diameter of 3 meters. Which statement about the circumference and area is true?
A comparison of the area and circumference is not possible since the area cannot be determined
The numerical value of the circumference and area are equal.
The numerical value of the circumference is greater than the numerical value of the area.
O The numerical value of the circumference is less than the numerical value of the area.
Answer:
The numerical value of the circumference is greater than the numerical value of the area.
Step-by-step explanation:
Diameter = 3 meters
The radius is half of diameter so,
Radius = 3 ÷ 2 = 1.5 meters
Circumference = 2πr (r is the radius)
= 2 x π x 1.5 = 9.42 meters (rounded to 3 significant figures)
Area of a circle = π[tex]r^{2}[/tex]
= π x [tex]1.5^{2}[/tex]
= π x 2.25 = 7.06 meters
The true statement is
The numerical value of the circumference is greater than the numerical value of the area.
What is Area and Circumference?The space a circle takes up in a two-dimensional plane is known as the area of the circle.
The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.
we have,
Diameter = 3 m
Radius= D/2 = 3/2 m
So, Area of Circle
= πr²
= 3.14 x 3/2 x 3/2
= 7.065 m²
and, Circumference of circle
= 2πr
= 2 x 3.14 x 3/2
= 9.42 m
Thus, The numerical value of the circumference is greater than the numerical value of the area.

Which sum is equal to the expression - 5x3 + 2x2 + 9x+2/
(x²+ 2)²
Answer:
Option C
Step-by-step explanation:
Given expression is [tex]\frac{-5x^3+2x^2+9x+2}{(x^2+2)^2}[/tex]
Option A
[tex]\frac{A}{x^2+2}+ \frac{Bx+C}{(x^2+2)^2}[/tex]
= [tex]\frac{A(x^2+2)}{(x^2+2)^2}+ \frac{Bx+C}{(x^2+2)^2}[/tex]
= [tex]\frac{Ax^2+2A+Bx+C}{(x^2+2)^2}[/tex]
Numerator is a quadratic polynomial, while the expression has the numerator as a cubic .
Therefore, both the expressions are not equivalent.
Option B
[tex]\frac{A}{(x^2+2)^2}+ \frac{Bx+C}{(x^2+2)^2}[/tex]
= [tex]\frac{A+Bx+C}{(x^2+2)^2}[/tex]
Here, numerator of the expression is a linear polynomial which is not equal to given expression.
Therefore, both the expressions are not equivalent.
Option C
[tex]\frac{Ax+B}{(x^2+2)}+ \frac{Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{(Ax+B)(x^2+2)}{(x^2+2)^2}+ \frac{Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{Ax^3+Bx^2+2Ax+2B+Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{Ax^3+Bx^2+x(2A+C)+D}{(x^2+2)^2}[/tex]
Here, numerator is a cubic polynomial.
Therefore, both the expressions are equivalent.
Option D
[tex]\frac{Ax+B}{(x^2+2)^2}+ \frac{Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{x(A+C)+(B+D)}{(x^2+2)^2}[/tex]
Numerator is a linear polynomial.
Therefore, sum is not equal to the given expression.
Option C will be the answer.

The seventh-grade class is putting on a variety show to raise money. It costs $150 to rent the auditorium that they are going to use. If they charge $5 per ticket, how many tickets do they need to see in order to raise at least $750?
Answer:
180 tickets
Step-by-step explanation:
750 + 150 = 900 they will have to make
900/5 = 180 tickets
To raise at least $750, the seventh-grade class needs to sell a minimum of 180 tickets, priced at $5 each, to cover the fundraising goal and the $150 auditorium rental cost.
Given that,
Seventh-grade class is putting on a variety show to raise money.
The auditorium rental cost is $150.
Each ticket is priced at $5.
The goal is to raise at least $750.
Denote the number of tickets they need to sell as "x".
The revenue generated from ticket sales can be calculated by multiplying the number of tickets sold (x) by the ticket price ($5),
Which gives us 5x dollars.
Now since,
Total revenue from ticket sales - Auditorium rental cost ≥ Fundraising goal
Therefore,
5x - 150 ≥ 750
Add 150 to both sides:
5x ≥ 900
Divide both sides by 5 to solve for x:
x ≥ 180
Since the seventh-grade class cannot sell a fractional number of tickets,
Hence,
They need to sell at least 180 tickets to raise at least $750 and cover the auditorium rental cost.
