Jamie believes that applying a scale factor of 1 would result in an enlargement. Do you agree or disagree with her claim? Explain.
Answer:
If the scale factor is 1, the figure and the image are congruent.
Step-by-step explanation:
If the scale factor is less then one, then it would be a reduction, but if the scale factor is greater then one, it would be an enlargement.

Can yall give me 4 examples of rules of exponents with answers pls?
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]

Product of powers rule. ...

Answer: 120
120
Step-by-step explanation:
I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)
P/w = part/whole = ?/400
%/100= percent/100 = 30%/100
These numbers are equivalent
If you don’t understand the top then here is how to do the work-
400x30=12000
12000/100=120
Therefore it’s 120
Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.
How many loaves of banana bread can she make?
Answer:
69 loaves
Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)
First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.
So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread

Each pair of points lies on a line with the given slope. Find y.
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

solve for r: q = p(r + s)
Answer:
[tex]r=\frac{q-ps}{p}[/tex]
General Formulas and Concepts:
Order of Operations: BPEMDASEquality PropertiesDistributive PropertyStep-by-step explanation:
Step 1: Define equation
[tex]q=p(r+s)[/tex]
Step 2: Solve for r
Distribute p: [tex]q=pr+ps[/tex]Subtract ps on both sides: [tex]q-ps=pr[/tex]Divide both sides by p: [tex]\frac{q-ps}{p} =r[/tex]Rewrite: [tex]r=\frac{q-ps}{p}[/tex]Step-by-step explanation: To solve for r, start by distributing the p
through the parentheses on the left side to get q = pr + ps.
Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.
Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.
Answer:
Step-by-step explanation:
Given
There are 9 people going on a trip
They purchased coach tickets =$160
first class tickets =$1180
total budget to spend = $4500
Let coach tickets=X
So first class tickets=9-x
160x+1180(9-x)=4500
160+10620-1180x=4500
160x-1180x=4500-10620
-1020x=-6120
X=6120/1020
X=6
So answer
Coach tickets=X=6
First class tickets=(9-x)
=3.

Write a linear equation in slope-intercept form to represent the data shown in this table.
Bicycle Rental Costs
Time, x(hours) Total cost, y(dollars)
1 $8
2 $16
3 $24
Show your work.
Answer:
[tex]\displaystyle y=8x[/tex]
Step-by-step explanation:
We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.
So, we will first need to determine the slope. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are two points.
We have three points: (1, 8), (2, 16), and (3, 24).
Let’s pick two. We can use (1, 8) and (2, 16).
So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{8}{1}=8[/tex]
So, our slope is 8.
Now, we can determine the equation using point-slope form:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is a point.
We know that the slope is 8, so we will substitute 8 for m.
We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:
[tex]\displaystyle y-8=8(x-1)[/tex]
Solve for y. Distribute the right:
[tex]\displaystyle y-8=8x-8[/tex]
Add 8 to both sides:
[tex]\displaystyle y=8x[/tex]
And we have our equation.
Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.
