Slope :3 y-intercept :1
Answer:
y = 3x + 1
Step-by-step explanation:
y = mx + b
The slope, or m, is 3.
The y-intercept, or y, is 1.
Plug them into the equation.
y = mx + b
y = 3x + 1

The ratio of collectible cards Kyle owns to cards that Zeona owns is 3:2. Zeona has 36 cards. How will the ratio of Kyle’s cards to Zeona’s cards change if they both sell half of their cards? Explain.
Answer:
It wouldn't.
Step-by-step explanation:
With the ratio, since Zeona has 36 cards, Kyle must have 54. If they each sold half, Kyle would have 27 and Zeona would have 18. So, the ratio would still be 3:2.

A box of crayons costs $1.75, including tax. Mr. Valentino wants to purchase boxes of crayons for his class and has a $25 budget. Write an inequality to solve for the number of boxes of crayons Mr. Valentino can purchase.
NEED HELP PLZZZ :( WILL GIVE BRAINIEST IF RIGHT
A $1.75x ≤ $25
B $1.75x ≥ $25
C $25x ≤ $1.75
D $25x ≥ $1.75
Answer:
A ) $1.75 x ≤ $25
Step-by-step explanation:
the cost of x boxes of crayons = 1.75x dollars
If there is a budget of only $ 25,
So, the cost of x boxes of crayons ≤ $25
Answer:
Since his budget is 25, it's less than or equal to ( ≤ 25). That means your answer would be A $1.75x ≤ $25 because 1.75 times the amount of crayons can't go over the $25 budget.

What is the inverse operation of addition?
Answer:Inverse operations are opposite operations. Subtraction is the inverse of addition and division is the inverse of multiplication.
Step-by-step explanation:
Consider the equation 3x+10=2x+10. Does this equation have one solution, infinitely many solutions, or no solutions? Explain your answer.
Answer:
One solution: x = 0
Step-by-step explanation:
Starting with 3x+10=2x+10,
subtract 2x from both sides. We get x + 10 = 10, or x = 0. This equation has ONE solution, x = 0.

Answer:
[tex]\frac{4a-2}{2a+1}[/tex]
Step-by-step explanation:
Factorise the numerator and denominator
8a² - 2 ← factor out 2 from each term
= 2(4a² - 1) ← 4a² - 1 is a difference of squares
= 2(2a - 1)(2a + 1)
4a² + 4a + 1 ← is a perfect square
= (2a + 1)²
Thus
[tex]\frac{8a^2-2}{4a^2+4a+1}[/tex]
= [tex]\frac{2(2a-1)(2a+1)}{(2a+1)(2a+1)}[/tex] ← cancel (2a + 1) on numerator/ denominator
= [tex]\frac{2(2a-1)}{2a+1}[/tex]
= [tex]\frac{4a-2}{2a+1}[/tex]

how do I solve these two problems please explan how you got the answer
Answer:
They want you to have a good "grasp" of algebra... since you're asking about this I'm going to guess you don't feel that comfortable with it ... so I'll go in detail below. Even thought this is exactly what your math teacher is supposed to be teaching you.. ask your math teacher if I can have part of their salary :) $$
Step-by-step explanation:
in Question 18 , they are asking to solve for y . what that means is they want an equation that looks like y= (some stuff) In math terms they are asking you to isolate the y ... which is the part your math teacher should have told you.. were you just not listening? :P Anyway, soooo to solve for y we want to get y by it self.. on one side of the = sign and everything else on the other.. to do this use the order of operations ... but.. for doing algebra it has to be done in reverse order :0.... which i'm sure your math teacher hasn't mentioned and partly why algebra is so difficult.
soooo solve for 'y' ( isolate y )
12x-4y=20
-4y=20-12x
y=(20-12x)/-4
Yes, I know.. that answer is not very "satisfying" but. that is solved for "y"
for Question 20 it's just straight algebra, no numbers.. it's more abstract...and solve for R ( isolate 'R') to get R by itself
P=(R-C) / N
I'm multiplying by N first b/c the next thing in those parenthesis and when you do the order of operations you'd usually to that first but remember we are going back wards in operations.. sooo multiply both sides by N
P*N=R-C ..
now that R-C is no longer in parenthesis we can do that addition of C to both sides.. this is kinda tricky b/c of how the R-C were both over the N anyway...
P*N +C=R
another way to think of this one.... maybe you don't want to and you can just skip this part if you want to be done...
P=(R-C)/N
P=R/N - C/N now we can do addition first .. like I was mentioning above
P+C/N = R/N multiply both sides by N
N(P+C/N)=R b/c N/N =1 just drop it from the R'
P*N +C =R we end up at the same place but my a different route.

(URGENT!! PLS HELP) The color of paint used to paint a race car includes a mixture of yellow and green paint. Scotty wants to lighten the color by increasing the amount of yellow paint 30%. If a new mixture contains 3.9 liters of yellow paint, how many liters of yellow paint did he use in the previous mixture?
Answer:
3 litersStep-by-step explanation:
Let the initial amount of yellow paint be x
Then we have x increased by 30% equals 3.9 liters:
x + 0.3x = 3.91.3x = 3.9x = 3.9/1.3x = 3 litersCharlotte is in the business of manufacturing phones. She must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. The labor and materials cost $100 for each phone manufactured, and the total cost of producing 8 phones in a day would be $1300. Write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.
Answer:
C=100+162.5pStep-by-step explanation:
In this problem, we want to write a model/equation that will represent the cost of producing a phone
Given, labor and materials cost per phone is $100
the cost of producing 8 phones a day is $1300
let us find the cost of producing one phone a day
8 phone is produced for $1300
1 phone will be for x
x= 1300/8
x=$162.5
The cost of producing a phone in a day is $162.5
therefore the of producing p phone in a day is 162.5p
if C represents the total cost of producing a phone
then total cost, in dollars, of producing p phones in a given day.
C=100+162.5p
Answer: C = 100p + 500
