Answer:
They have the same slope
Step-by-step explanation:
Given
[tex]y = -\frac{5}{2}x[/tex]
[tex]y = -\frac{5}{2}x + 8[/tex]
Required
Determine the true statement about both lines
An equation has a general format of:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparing this to the equations of both lines, we have that:
For line 1:
[tex]m = -\frac{5}{2}[/tex]
For line 2:
[tex]m = -\frac{5}{2}[/tex]
Compare the slopes of both lines, we have that:
[tex]m = m = -\frac{5}{2}[/tex]
Hence, we can conclude that both lines have the same slope

Cara and marcus shared a candy bar. The models are shaded to show the fraction of the candy bar each of them ate. What fraction of the candy bar did Cara and Marcus eat altogether?
Answer:
A. 11/12
Step-by-step explanation:
A. 11/12
B. 9/16
C. 1/12
D. 9/24
Cara = 8/12 candy bars
Marcus = 1/4 candy bars
What fraction of the candy bar did Cara and Marcus eat altogether?
Total candy bars = Cara + Marcus
= 8/12 + 1/4
= 8+3/12
= 11/12 candy bars
The correct answer is A. 11/12

Step-by-step explanation:
Credit card A has an APR of 27.2% and an annual fee of $96, while credit card B has an APR of 30.3% and no annual fee. All else being equal, which of these equations can be used to solve the principal P for which the cards offer the same deal over the course of a year
Answer: D. P * (1 + 0.272/12)¹² + 96 = P * (1 + 0.303/12)¹²
Step-by-step explanation:
Credit Card A deal over the course of a year:
Payments are done per month so values need to be converted to monthly figures.
APR per month = 27.2%/12
Period = 1 year * 12 months = 12
= P * (1 + 27.2%/12)¹² + 96
Credit Card B deal over a year
= P * (1 + 30.3%/12)¹²
The Principal that will enable both cards to offer the same deal will therefore be:
P * (1 + 27.2%/12)¹² + 96 = P * (1 + 30.3%/12)¹²

a circle with a radius 3 centimeters is cut from square piece of felt. the side of the felt square are 8 centimeters long. How much felt is left over? use 3.14 for (pie symbol). show your work.
Answer:
There are [tex]35.74\ cm^2[/tex] of felt left over.
Step-by-step explanation:
The side of the felt square is 8 cm. A circle of radius 3 cm is cut from the square piece of felt.
The portion of felt leftover is the difference between the area of the square and the area of the circle.
The area of the square is:
[tex]A_s=(8\ cm)^2=64\ cm^2[/tex]
The area of the circle is:
[tex]A_c=\pi(3\ cm)^2=3.14*9\ cm^2[/tex]
[tex]A_c=28.26\ cm^2[/tex]
The remaining area of the piece of felt is:
[tex]A=64\ cm^2-28.26\ cm^2[/tex]
[tex]A=35.74\ cm^2[/tex]
There are [tex]35.74\ cm^2[/tex] of felt left over.
If using the method of completing the square to solve the quadratic equation x^2+8x-4=0 which number would have to be added to "complete the square"?
I need the answer ASAP. Please help. Thank you
x^2 + 8x - 4 = 0
(x^2 + 8x + 8/2^2) - 4 - 8/2^2 = 0
(x^2 + 8x + 16) - 4 - 16 = 0
(x^2 + 8x + 16) - 20 = 0
(x + 4)(x + 4) - 20 = 0
The number that is to be added to complete the square is 8/2^2, or 16.

Answer:
y = [tex]\frac{1}{2}[/tex] x + 4
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, 8) and (x₂, y₂ ) = (10, 9)
m = [tex]\frac{9-8}{10-8}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 8) , then
8 = 4 + c ⇒ c = 8 - 4 = 4
y = [tex]\frac{1}{2}[/tex] x + 4 ← equation of line
Is the Point on the Line?
Answer:
yes.
Step-by-step explanation:
The eqation of the line is y=1/2x+3 so when we plug in x as 20 y is equal to 13
Answer:
Yes it is on the line becuase if you find the slope of the line which is 1/2. We can just use rise over run from there. So we know 1 is y and 2 is x Becuase slope is written in y/x. And we can fins slope by just calculating the rise over run or suing the formula y2-y1/x2-x1. So the last pont shown on the line is (10,8) so we can add 1 to the y or in this case 8 and add 2 to the x or in this case 10. You’ll get (12,9). We know this works becuase if you find the slope of (12,9) and (10, 8), you’ll get 1/2 again which is the same slope so we know it’s right. Now we just add using the same slope to the now new point. We add 1 to 9 and add 2 to 12. (14,10). Still, if you find the slope, it’ll still be 1/2. Now keep repeating that and you’ll get (20, 13) eventually. And we can check by calculating the slope. (20,13) and (10,8), you could use any point on the coordinate plane/ and you’ll get 1/2. A easier way could just be calculating the slope first and you’ll get 1/2 from any two points and then use any two points to calculate the slope for (20,13). It’ll still be the same thing.

Answer:
2x + 7y and 7g + 3h
Step-by-step explanation:
(a)
3x + 5y - x + 2y ← collect like terms
= (3x - x) + (5y + 2y)
= 2x + 7y
(b)
3g + 5h + 4g - 2h ← collect like terms
= (3g + 4g) + (5h - 2h)
= 7g + 3h
Answer:
A) 2x + 7y
B) 7g + 3h
Step-by-step explanation:
A) 3x + 5y - x +2y =
3x - x = 2x
5y + 2y = 7y ans: 2x + 7y
B) 3g + 5h +4g - 2h =
3g + 4g = 7g
5h - 2h = 3h ans: 7g + 3h
9. What is the value to x in the inequality -4(6 + 5x) - 7 < - 9(2x+ 3)
Answer:
x [tex]\geq[/tex] -2
Step-by-step explanation:
Remove parentheses and distribute -4 and -9, calculate the difference, move the variable and constant, collect like terms. ( -2x [tex]\leq[/tex] 4), and divide both sides, and you'll end with -2.
Answer:
x > -2 (last choice)
Step-by-step explanation:
Using the distributive property multiple -4 to both integers
-24 - 20x - 7 < -18x - 27
-31 - 20x < -18x - 27
Add 27 on both sides
-4 - 20x < -18x
Add 20x on both sides
-4 < 2x
Divide each side by 2
x > -2

Answer:
D as in Dawg y = 27x + 180
Step-by-step explanation:
Plug in 1 for the last option.
27(1) + 180 = 207
You will get 207 and the table has 200. So 207 is the closest answer to 200. All the other answers are not even close. Like 72 and etc

15 - (-5) =
Answer: 20
===========================================
Explanation:
The two negatives cancel to form a positive. A negative is just opposite. So we have two opposites canceling.
15 - (-5) = 15 + 5 = 20

Here's another way to look at it:
Let's say we're on the 15th floor of a skyscraper. We can think of each floor of the skyscraper as part of a vertical number line (or ruler).
If we go up 5 floors, then we write 15+5 = 20 showing we end up on the 20th floor.
If we go down 5 floors, then we write 15-5 = 10
Adding makes us go up, subtracting makes us go down.
If we add on a positive number, then we go up, but adding on a negative number ultimately has us go downward.
This is because of something like 15 + (-5) = 15 - 5 = 10.
Subtracting a negative is really the same as adding. Subtracting pulls us down, but the negative counterbalances things to go the opposite direction (going up). So that's why 15-(-5) = 15+5 = 20.
--------------
Yet another way to look at it:
Negative values are useful in finance when talking about debt.
If you have 5 iou's of debt, then we write this as -5
If you transfer that debt to a friend whos account balance is $15, then their balance becomes 15 + (-5) = 10 dollars. They would have 10 dollars left after paying the debt.
Now let's say the friend got those iou's taken away and someone else paid for them. That would mean we would say 15 - (-5) = 15+5 = 20 is that first friend's new balance. Effectively they got 5 additional dollars when that debt was taken off their hands.

The Crazy 80s Baby Jr. Decides to make a Crazy Cake for dessert. The cake uses eggs and potatoes in a ratio of 2:5. If she uses 6 eggs, how many potatoes will she need?
Answer:
When
eggs = 6, Potatoes = 15
Step-by-step explanation:
Ratio of egg to potatoes
Egg : potatoes
2 : 5
If she uses 6 eggs, how many potatoes will she need?
Eggs = 6
Potatoes = x
2 : 5 = 6 : x
2 / 5 = 6 / x
Cross product
2 * x = 5 * 6
2x = 30
x = 30 / 2
x = 15
When
eggs = 6, Potatoes = 15

This is due by tomorrow night and I need help
Answer:
AY = 16
IY = 9
FG = 30
PA = 24
Step-by-step explanation:
The centroid of the triangle divides each median at the ratio 1: 2 from the base
Let us solve the problem
In Δ AFT
∵ Y is the centroid
∵ AP, TI, and FG are medians
→ By using the rule above
∴ Y divides AP at ratio 1: 2 from the base FT
∴ AY = 2 YP
∵ YP = 8
∴ AY = 2(8)
∴ AY = 16
∵ PA = AY + YP
∴ AP = 16 + 8
∴ AP = 24
∵ Y divides TI at ratio 1: 2 from the base FA
∴ TY = 2 IY
∵ TY = 18
∴ 18 = 2
→ Divide both sides by 2
∴ 9 = IY
∴ IY = 9
∵ Y divides FG at ratio 1:2 from the base AT
∴ FY = 2 YG
∵ FY = 20
∴ 20 = 2 YG
→ Divide both sides by 2
∴ 10 = YG
∴ YG = 10
∵ FG = YG + FY
∴ FG = 10 + 20
∴ FG = 30
