Describe the graph that is produced by the equation (x-7)^2+(y+5)^2>25
Step-by-step explanation:
The equation will form a circle because it in the form of
[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]
First, let set the equation equal.
[tex](x - 7) {}^{2} + (y + 5) {}^{2} = 25[/tex]
Here the center will be (7,-5), and the radius of 5. The boundary line will be dashed
Since this is in the inequalities, we must find the solution set.
Plug in 0,0 for x and y and see if it's true.
[tex](0 - 7) {}^{2} + (0 + 5) {}^{2} > 25[/tex]
[tex]49 + 25 > 25[/tex]
[tex]74 > 25[/tex]
This is a true so we shade the region that includes 0,0
Since 0,0 has a greater distance from the center of the circle, 0,0 is outside of the circle, so our solution set will
be outside of circle.
Here a picture of graph,

Darlene and Lenny picked apples. Darlene filled 14 baskets and Lenny filled 8. if each basket holds 24 apples, how many more apples did Darlene pick than Lenny?
A.112
B.144
C.192
D.336
Answer: B. 144
Step-by-step explanation: It's 144 because if you multiply 14 x 24 you get 336 and then you multiply 8 x 24 and you get 192. Now you subtract 336 - 192 and you get 144.

There are 40 students in class A. There are 5% more students in class B. How many students are in class B?
Answer:
Solution,
⇒Total students in class A=40
⇒Class B=5%
Now,
5% of 40 students
→5/100 × 40=2 students
Again,
→Number of students in class B =40 students + 2 students
=42 students
Hence, there were 42 students in class B.
Step-by-step explanation:
There are 42 students in class B which is more than 5% of the number of students in class A.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."
Given:
In Class A,
there are 40 students in total.
For class B,
we have a condition that there are 5% more students in class B.
Let n be the students in class B.
So, applying the percentage formula,
we get,
n = 40 + 40 x 5 /100
n = 40 + 200/100
n = 40 + 2
n = 42.
Therefore, the number of students in class B = 42.

Solve the system of linear equations by substitution.
3x - 2y = 11
x + 2y = 9
The solution of the system is
Answer:
x=5, y=2
Step-by-step explanation:
1) Subtract 2y from both sides of x+2y to get x=9-2y
2) Substitute x into the first equation to get 3(9-2y)-2y=11
3) Solve for y (y=2)
4) Plug y into either equation: x+2(2)=9 x=5
5) The answer is (5, 2)

Darnell buys homes and flips them by completing renovations to turn a profit on his investment. He is currently working on a house with three bedrooms that need new hardwood floors. He is estimating the total cost to purchase hardwood flooring for the bedrooms with the following dimensions.
Bedroom 1: 22 feet by 15 feet
Bedroom 2: 15 feet by 12 feet
Bedroom 3: 13 feet by 12 feet
A big home improvement store advertises the price of two types of flooring, shown below.
$7.25 per square foot
$6.75 per square foot plus a $100 fixed installation fee
Which of these two prices would be best for Darnell to estimate the total cost of new hardwood flooring in the three bedrooms?
Answer:
Look below for answer! Have a great day and please mark me brainliest!
Step-by-step explanation:
Bedroom 1: 22x15=330
330x7.25=2392.5
Bedroom 2: 15x12=180
180x7.25=1305
Bedroom 3: 13x12=156
156x7.25=1131
2392.5+1305+1131= 4828.5
Bedroom 1: 22x15=330
330x6.75=2227.5
Bedroom 2: 15x12=180
180x6.75=1215
Bedroom 3: 13x12=156
156x6.75=1053
2227.5+1215+1053+100= 4595.5
Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.

I will attach a screenshot of the math problem.
Complete the table for the function y = 0.1^x
The first step: plug values from the left column into the ‘x’ spot in the formula y=0.1^x.
* 0.1^-2 : We can eliminate the negative exponent value by using the rule a^-1 = 1/a. Keep this rule in mind for future problems. (0.1^-2 = 1/0.1 * 0.1 = 100).
* 0.1^-1 = 1/0.1 = 10
* 0.1^0 = 1 : (Remember this rule: a^0 = 1)
* 0.1^1 = 0.1
Our list of values: 100, 10, 1, 0.1
Now, we can plug these values into your table:
