Find the midpoint of A and B where A has coordinates (-7, 1)
and B has coordinates (3,-5).
Answers
Answer:
A (-7, 1) = (X1, Y1)
B (3, -5) = (X1, Y2)
Now,
Mid point = (X1 + X2÷2, Y1 + Y2 ÷ 2)
= {-7+3÷2, 1+(-5)÷2}
= (-4÷2, 1-5÷2)
= (-4÷2, -4÷2)
= (-2, -2)

After how many weeks will Andre and Elena have the same amount of money in their savings accounts?
They will have the same amount at blank weeks. They will both have $blank in their account. This is the solution because the point ( blank, blank) is blank both lines and make both equations blank?
Answers
1. Solve what Andre did.
$5 multiplied by 4 weeks = $20. So, $100 + $20 = $120.
2. Solve what Elena did.
$20 × 4 weeks = $80. $10 from her savings account + $80 = $90
3. So, Andre has more money because he started with $100, which is lots of money. And Elena only started with $10. So, Andre has $30 more than Elena.
4. For Part B, you have to count how many weeks in order for both of them to have the same amount of money left in their savings account.
5. Since Andre gets $5 a week, he can get at least 2 weeks and get $130. And for Elena, she would have to do 2 weeks also. For now she has $90, but for two weeks would be $130.
Answer for Part B: Each of them would have to do 2 weeks to get the same amount. (Which is 4 weeks)
Write an equation in point slope form of the line that passes through the point -4, 5 and has the slope of one.
Answers
Answer:
y - 5 = x + 4
Step-by-step explanation:
Use point slope form, y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line
Plug in the given point and slope:
y - y1 = m(x - x1)
y - 5 = 1(x + 4)
Simplify:
y - 5 = x + 4
So, the point slope form of the line is y - 5 = x + 4

Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price. The shoe store’s clerks are paid on commission. If the clerk receives a 12% commission on total purchase amounts before tax is applied, how much would the commission be for Isaac’s purchase with and without a coupon?

It lagged earlier when I first asked
Answers
Answer:
9 girls did not make the team
Step-by-step explanation:
20*45=900
900/100=9
Answer:
9 girls didn't make the team
Step-by-step explanation:
The person above did it a great way, and that is the way I use it, but if you want a method that involves fractions here it is: 20% is the same as 1/5. Since there are 45 girls total, we need to find 1/5 of 45 and you can achieve that by multiplying 45 by 1/5 and you get 45/5 which is 9. Hope this helped :) .

Hey you! Yes you! You are awesome! Can you help me?
Answers
Answer:
a = -40
Step-by-step explanation:
In order for a system of equations to have infinitely many solutions, the equations must have the same line when graphed. Knowing this, it also means that the equations equal the same thing - they're just written differently. Also, remember that a constant term is just a number with no variables.
First, I would organize the second equation into standard format just like the first one (moving the x and y terms to the left side):
[tex]6x = 16 + a -15y\\6x + 15y = 16 + a[/tex]
Then, by comparing the x and y terms in both equations, we can see that the second equation is just the first equation multiplied by 3. (Notice how 2x times 3 is 6x, and 5y times 3 is 15y.) So, we would need our constant on the left hand side to do the same, to equal -8 times 3, or -24.
Thus, we would need to find what added to 16 equals -24, and we can do this with a simple algebra equation:
[tex]a + 16 = -24\\a = -40[/tex]
Therefore, a would need to equal -40 in order for the system to have infinitely many solutions.

A music store buys instruments and then sells them for 30% more than they paid.
During a 20% off sale, the store offers a clarinet for $93.60.
How much did the store pay for the clarinet?
Answers
$93.60 x 0.2 = $18.72
$93.60 + $18.72 = $112.32 = Price before 20% discount.
$112.32 ÷ 100 x 30 = $33. 696 = Discount of 30%
$112.32 - $33.696 = $78.624 = Original Price
Therefore, the store paid $78.624 for the clarinet before the 30% markup and 20% discount.
It's just a process of working backwards.
Hope this helps :))
Factor the polynomial by finding the greatest common factor.
-15y^7z^6 – 3y^3z^8
Answers
Explanation: The first number in the parenthesis has to be positive, so the GCF in this problem will be negative. The GCF between the coefficients is 3. The GCF between the y variable is y^3. The GCF between the z variable is z^6. We combine all of the GCFs to get an overall GCF: -3y^3z^6. Then we will factor it out of the two terms, giving us: -3y^3z^6(5y^4+z^2). You can check the answer by multiplying them to see if you get the original expression.

Answer:
We conclude that:
g(-3) = 3.5Step-by-step explanation:
Some background Concepts:
From the graph, it is clear that at x = -10, the graph intersects the x-axis.
So, the x-intercept of the graph is (-10, 0).
It means g(-10) = 0
From the graph, it is clear that at y = 5, the graph intersects the y-axis.
So, the y-intercept of the graph is (0, 5).
It means g(0) = 5
Determining g(-3):
From the graph, it is clear that at x = -3, the value of the function output = 3.5.
In other words,
at x = -3, g(-3) = 3.5
Therefore, we conclude that:
g(-3) = 3.5what is 2.23607 as a fraction

distributive property
Step-by-step explanation:
5(18)=2(18)+3(18)
Distributive property
c(a+b) = ca+cb
We are using the left hand side and adding a+b
18(2+3) = 2* 18+ 3*18
18*5 = 2* 18+ 3*18
