Answer:
[tex]y=-\frac{7}{4}x^2+7x-3\\[/tex]
Step-by-step explanation:
y - 4 = C(x - 2)²
y-intercept = -3, so x = 0, y = -3
-3 - 4 = C(2)²
so C = -7/4
[tex]y = -\frac{7}{4}(x-2)^2+4=-\frac{7}{4}(x^2-4x+4)+4=-\frac{7}{4}x^2+7x-7+4\\y=-\frac{7}{4}x^2+7x-3\\[/tex]

Ordered pair for 3x + 5y = 2
9x + 11y = 14
Answer:
y = -3/5x +2 y = -9/11 + 14
Step-by-step explanation:
3x + 5y = 2(subtract 3x on both sides)
5y = -3x +2(divide by 5)
y = -3/5x + 2
9x + 11y = 14 (subtract 9x on both sides)
11y = -9x + 14 (divide by 11)
y = -9/11x + 14
Answer:
Step-by-step explanation:
-9x - 15y = -6
9x + 11y = 14
-4y = 8
y = -2
3x + 5(-2) = 2
3x - 10 = 2
3x = 12
x = 4

Step-by-step explanation:
A bus makes a stop at 2:30, letting off 13 people and letting on 4. The bus makes another stop ten minutes later to let off 2 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?
Answer:
The original number of passengers on the bus decreased by 10 after the second stop
Now, at 2:30:
15 passengers got off and 9 got on.
This means that:
number of passengers = x - 15 + 9
number of passengers = x -6
10 minutes later:
4 passengers got off the bus
This means that:
number of passengers = (x-6) - 4
number of passengers = x - 10
By comparing, we can note that:
The original number of passengers on the bus decreased by 10 after the second stop

a teacher wants to paint a wall wit a door in a classroim. the entire wall is a 12 ft by 10 ft rectangle, and the foor is a 3ft by 8ft rectangle
Answer:
The answer is 144 square feet.
Step-by-step explanation:
if you are trying to find the sum of the room, then you multiply 10 and 12 which equals 120 then you multiply 8 and 3 and that equals 24, then you add your two answers (120+24) and that equals 144 square feet.

to prepare for a party, Mark buys a small bunch of balloons for $6 and gift bags that cost $5.15 each. he spends a total of $72.95 on the balloons and a gift bag for each person he invited to his party- what is the number of person he invited?
Answer:
p=13
Step-by-step explanation:
let p = people
72.95=5.15p+6
-6
56.95=5.15
/5.15
p=13
Answer:
Equation:5.14x+6=72.95
Answer:13 people
Step-by-step explanation:
5.15x+6=72.95
-6 on both sides
5.15x=72.95
divide by 5.15 on both sides
x=13 people

Explaining Equivalent equations
What are equivalent equations? How do you find them?
Write a few sentences describing them.
Answer:
Equivalent equations are equations that have exactly the same solution. To find equivalent equations, it is best to solve them individually to find the solutions. The ones with the same solution in the end are considered equivalent equations.
Answer:
Sample Response: Equivalent equations have the same solution. You can create equivalent equations by performing the same operations on each side of the equation. You can check for equivalence by finding the solution for each equation.

If 106 people attend a concert and tickets for adults cost four dollars what ticket for a children cost $3.75 and total receipt for the concert was $414 how much of each went to the concert
Answer:
A = 66 adults, C = 40 children
Step-by-step explanation:
We can set up a system of equations to find how many adults and how many children attended the concert, with A representing the adults and C representing the children:
[tex]A + C = 106\\4A+3.75C=414[/tex]
We can use the elimination method and multiply everything in the first equation by -4
[tex]-4(A+C=106)\\-4A-4C=-424\\4A+3.75C=414[/tex]
Once we add the values together, we're left with:
[tex]-0.25C = -10[/tex], where solving for C gives us C = 40
We can plug C into the first equation to find A: [tex]A+40=106[/tex], where solving for A gives us A = 66

The GCF of 12 and 28 is _____.
greatest common factor 12 and 28 is 4
The greatest common factor (GCF) of 12 and 28 is 4.
To find the GCF, you can determine the factors of both numbers and identify the greatest common factor they share.
As we know that a factor is a number that entirely divides another number.
To put it another way, any two integers that multiply to generate a result are factors of the result.
For 12, the factors are 1, 2, 3, 4, 6, and 12.
For 28, the factors are 1, 2, 4, 7, 14, and 28.
The common factors of 12 and 28 are 1, 2, and 4.
Among them, the greatest common factor is 4.
Therefore, the GCF of 12 and 28 is 4.
