Parallel lines have the same slope
y = -3x + b
Plug in the x and y values from the point
5 = -3(-4) + b
5 = 12 + b
-7 = b
Answer to 7: y = -3x -7
8:
Perpendicular lines have opposite reciprocal slopes
y = -2x + b
Plug in x and y from the point
-6 = -2(7) + b
-6 = -14 + b
8 = b
Answer to 8: y = -2x + 8

A frosting recipe calls for adding 5 tsp of red food coloring for every 3 tsp of blue food coloring. If you used 15 tsp of blue food coloring, how many tsp of red food coloring would you use to get the same recipe of frosting ?
Answers
Answer:
tsp of red food coloring = 25
Step-by-step explanation:
Red food coloring = 5 tsp
Blue food coloring = 3 tsp
Red food coloring : Blue food coloring = 5 tsp : 3 tsp
Blue food coloring = 15 tsp
how many tsp of red food coloring would you use to get the same recipe of frosting ?
Let
x = tsp of red food coloring
Red food coloring : Blue food coloring = x tsp : 15 tsp
Equate the ratios to find x
Red food coloring : Blue food coloring
5 tsp : 3 tsp = x tsp : 15 tsp
5 / 3 = x / 15
Cross product
5 * 15 = 3 * x
75 = 3x
Divide both sides by 3
x = 75 / 3
= 25
x = 25 tsp
tsp of red food coloring = 25

Given that 4x−5y=39
Find y when x=3
Give your answer as an improper fraction in its simplest form.
Answers
Answer:
- [tex]\frac{27}{25\\}[/tex]
Step-by-step explanation:
4x−5y=39
for x=3
12 - 5y = 39
-5y = 39 -12
-5y = [tex]\frac{27}{5\\}[/tex]
-y = [tex]\frac{27}{25\\}[/tex]
y = - [tex]\frac{27}{25\\}[/tex] = -1 [tex]\frac{2}{25\\}\\[/tex]
-27/5 or -5 2/5
Step-by-step explanation:
4x-5y=39 while x=3
4(3)-5y=39 add x into bracket
12-5y=39 result of 4*3
12-5y-12=12-39 substrate non variable number to each side
5y = -27 the result from upper substraction
y= -27/5 the result mixed fraction form -5 2/5

Maritza says that the number y is equal to 5 less than -5 times x. Which of the following equations could be used to find the value of y?
Answers
Answer:
y= -5x-5
Step-by-step explanation:
Y is equal to 5 less than -5 times x, which means it is 5 less than -5x.
If y is 5 less than -5x, that means it is equal to -5x-5.
If you were to put that in an equation, it would be y= -5x-5

You and your friend go shopping with $846,375,593. (that's literally the question) You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories. How much money do you both have left?
Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?
Later, you earn $234,485.78. How much do you and your friend now have?
This is the actual question on my homework... I have no clue how to do this... can someone please help me? 50 points!
Answers
Answer:
Initial money -->$846,375,593
You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories.
$846,375,593-$250,678-$10,008-440,034 = $845,674,873
Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?
$845,674,873/2 = $422,837,436.5
You have $422,837,436.5 left.
Answer: Ok look at the explaination
Step-by-step explanation:
$846,375,593 - everything you spend = 846,074,873
You both have 846,074,873 after the shopping spree
To calcute how much is left after the robbery you divide the money you have left by two since the robber took half. Then your are left with 423,037,436
Then you earn money so add 234,458.78 to your 423,037,436 and you have 423,271,922
At the end you are left with $423,271,922

Answers
Answer:
x(5) = number of cents
Step-by-step explanation:
If x = the amount of nickels you have, since 1 nickel is 5 cents, you multiply the number of nickels times 5 to get the number of cents. x(5). Examples: 5 Nickels= 5(5) = 25 cents. 7 Nickels = 7(5) = 35. Just plug in the number of nickles for x and solve. Hope this helped! If it did, please give me brainliest. Thanks!

what is the difference between 3/8 and 61/64 redosed
Answers
Answer:
Distance between points = [tex]37/64\\[/tex]
Step-by-step explanation:
This is a relatively simple problem. Here we have to find the distance between two points on the number line.
The given two numbers are fractions and to find the difference between these two numbers, we have to make their denominators common.
One has denominator as 8 and the other as 64.
We make the common denominator as 64.
Then the fractions 24/64 are 61/64 and .
The distance between the two points = 61/64 - 24/64
= 37/64

Step-by-step explanation:
plz mark brainlyest
The probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of Braxton brushing both times = (0.72×0.85) = 0.612
The Probability of Arabella brushing both times = (0.82×0.79) = 0.6478
Hence, the probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.
