help me with these three quesions for brainiest:)
Answer:
See below.
Step-by-step explanation:
1) Two equations are equivalent if they have the same solutions.
2) As long as two expressions [tex]a[/tex] and [tex]b[/tex] are equal, so [tex]a=b[/tex], adding the same value for both sides still makes the equation true, so
[tex]a = b[/tex]
[tex]a + c = b + c[/tex] is true.
3) As long as two expressions [tex]a[/tex] and [tex]b[/tex] are equal, so [tex]a=b[/tex], subtracting the same value for both sides still makes the equation true, so
[tex]a = b[/tex]
[tex]a - c = b - c[/tex] is true.

two functions are given below how does the graph of p compare with the graph of q
Answer:
The answer should be choice B.
Step-by-step explanation:
By using the process of elimination, you can cross out choices A and D.
According to the equation, the slope is of p(x) is smaller than q(x), thus q(x) will be steeper than q(x).
The valid answer is B because choice C is wrong.
HELPPP PLEASE!!Three friends went shopping. They each bought one pair of shoes that
cost $20 and 4 shirts that cost x dollars.
1. Write an expression that represents this situation.
2. Simplify the expression.
Answer:
1. [tex]3 (20+4x)[/tex]
2. [tex]60 + 12x[/tex]
Step-by-step explanation:
1. Let's just focus on one person at the moment. One of the friends bought a single shirt for $20, and 4 shirts that cost x dollars. Therefore, a single person's expense can be shown as:
[tex]20 + 4x[/tex]
Where x is the number of shirts the person bought.
Each of the three friends had the exact same expenses too, so we multiply this by three:
[tex]3 (20+4x)[/tex]
2. Simplifying the above equation just means multiplying each term in the parentheses by the 3 outside it, so 3 times 20 is 60, and 4x time 3 is 12x. Therefore, the simplified expression is:
[tex]60 + 12x[/tex]

Answer:
minutes
Step-by-step explanation:
Let x be the time in the beginning (in minutes).
Given: The track team is trying to reduce their time for a relay race.
First they reduce their time by t^1=2.1 minutes.
Then they are able to reduce that time by t^2=1/10
If their final time is 3.96 minutes, then
X - t^1 - t^2 = 3.96
=> X = 3.96 + t^1 + t^2
=> X = 3.96 + 2.1 + 1/10
=> X = 6.16

Answer:
You need help with both or can I just help with one ?
Step-by-step explanation:
Answer:
14,275
1013
Step-by-step explanation:
1: To get the population in the year 2001 we would have to multiply 4500 by 1.08. To get the population in 2002 we would have to multiply: 4500(1.08)(1.08) or 4500(1.08)^2
Therefore you can write the following equation
4500(1.08)ⁿ where n is the number of years
we need is in 2015 and so n=15 so we have
4500(1.08)¹⁵=14274.5 which you should probably round to 14275
The second one is very similar to the first
to get from 1990 to 1991 you would multiply 5000*.93
so our equation would be
5000(.93)ⁿ where n is the number of years
1990-2012 is 22 so we have
5000(.93)²²=1012.96 which rounds to 1013

The rectangle on the right is a scaled copy of the rectangle on the left. Identify the
scale factor. Express your answer as a whole number or fraction in simplest form.
Answer:
Scale factor = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given question is incomplete; find the question in the attachment.
Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Corresponding dimension of preimage}}[/tex]
Scale factor = [tex]\frac{\text{Dimension of image rectangle B}}{\text{Corresponding dimension of preimage rectangle A}}[/tex]
From the figure attached,
Length of rectangle B = [tex]\frac{20}{3}[/tex]
Length of rectangle A = 20
Scale factor = [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, image rectangle A is dilated with by a scale factor of [tex]\frac{1}{3}[/tex].

Sherry can make 5 pies in 4 hours. How many hours does it take sherry to make 16 pies?
Plz hurry
Answer:12.8 hours
Step-by-step explanation:divide 5 by 4 you get 1.25 witch is one hour 15 min then you times 5 by 3 then add
Sherry make 16 pies in 12.9 hours.
What is Division method?
Division method is used to distributing a group of things into equal parts.
Given that;
Sherry can make 5 pies in 4 hours.
Now,
Since, Sherry can make 5 pies in 4 hours.
So, Sherry can make 1 pies in = 4/5 hours.
Thus, Sherry can make 16 pies in = 16 x 4/5 hours.
= 64/5 hours
= 12.9 hours
So, Sherry make 16 pies in 12.9 hours.

The perimeter of a triangle is 22cm. If one of the sides is 9cm,find the other sides if the area of the triangle is 20.976cm2
Answer:
Third side = 8.34 cm
Step-by-step explanation:
Given that,
The perimeter of a triangle, P = 22 cm
One side of a triangle, b = 9 cm
The area of the triangle, A = 20.976 cm²
The formula for the area of a triangle is given by :
[tex]A=\dfrac{1}{2}\times b\times h\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times 20.976}{9}\\\\h=4.66\ cm[/tex]
Perimeter = Sum of all sides
9 cm + 4.66 cm + x = 22
x = 22 - 13.66
x = 8.34 cm
So, the third side of the triangle is 8.34 cm.
A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
2y = 16x +14
y = 8x – 7
y = –8x + 7
2y = −16x − 14
Step-by-step explanation:
the answer is 2y=16x+14
The equations that could be the other equation are y = 8x - 7 and y = -8x + 7.
If the system of equations has no solution, then the other equation must not have the same slope-intercept form as the first equation.
The slope-intercept form of the equation y = 8x + 7 is y = mx + b, where m is the slope and b is the y-intercept. Thus, the slope of the first equation is 8 and the y-intercept is 7.
Now let's check each of the given equations to see which one could be the other equation.
2y = 16x + 14
Rewriting this equation in slope-intercept form, we get y = 8x + 7, which is the same as the first equation. Therefore, this equation cannot be the other equation.
y = 8x – 7
This equation has the same slope as the first equation but a different y-intercept. Therefore, it represents a different line and could be the other equation.
y = –8x + 7
This equation has a slope that is the negative of the slope of the first equation, so it represents a different line. Therefore, it could be the other equation.
2y = −16x − 14
Rewriting this equation in slope-intercept form, we get y = -8x - 7, which has the same slope as the first equation but a different y-intercept. Therefore, it represents a different line and could be the other equation.
