Answer:

  y = -3x^2 +3x +6

Step-by-step explanation:

For roots p and q, the equation can be written as ...

  y = a(x -p)(x -q)

The value of 'a' must be determined so that the product apq is equal to the y-intercept. One could say that the formula is ...

  y = (y-intercept)/(pq)·(x -p)(x -q)

For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...

  y = 6/(2(-1))(x -2)(x +1)

  y = -3(x^2 -x -2) . . . . . simplifying a bit

  y = -3x^2 +3x +6

Answer: 14x+4

Step-by-step explanation

Add the expressions.

11x -2+3x+6

Remove parentheses.

11 x -2+3x+6

Add 11 x and 3x

14x-2+6

Add -2 and 6

14x+4

Answer:

a) 5m

b) $26.25

Step-by-step explanation:

You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food.

a) Write an algebraic expression for the total amount of money contributed for money?

Let the total Amount of money each person contributed be = m

Since each person contributed the same amount , and there are 5 people(you and 4 friends)

The total amount of money contributed = 5 × m

= 5m

b) Evaluate you expression if each person get $5.25

From the answer in question a, we have algebraic expression = 5m

m = $5.25

Total cost = 5 × $5.25

= $26.25

Answer:

A

Step-by-step explanation:

Answer:

The answer is 96%.

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 55 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 55, so we can write it down as 100%=55.

4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.

5. Now we have two simple equations:

1) 100%=55

2) x%=52.8

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=55/52.8

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52.8 is what percent of 55

100%/x%=55/52.8

(100/x)*x=(55/52.8)*x       - we multiply both sides of the equation by x

100=1.0416666666667*x       - we divide both sides of the equation by (1.0416666666667) to get x

100/1.0416666666667=x

96=x

x=96

now we have:

52.8 is 96% of 55

Answer:

32

Step-by-step explanation:

let the space be x

x + 27 + x + 27 + x = 150

3x + 54 = 150

3x = 96

x= 32

Answer:

No

Step-by-step explanation:

1 to 2 is 1/2

Answer:

No. See below.

Step-by-step explanation:

I've never heard anyone say this out loud. However, on Brainly, it is always interpreted as 1 1/2 = 1.5. So it is 1 plus 1/2.

1 to 2 is a ratio. For every set of car keys I have 2 house keys.

1 to 2 can be written either as 1/2 or 1:2 depending on how touchy your instructor is.

So no. 1 1/2 is not the same as 1:2

Answer:

slope of the line is one

Step-by-step explanation:

goes up one, over one.

The slope is 1

To find slope, you first find two points on a graph. Pick one of the two and count to the other one and that gives you your slope! I hope I helped! :)

Answer:

the answer is A -15

Step-by-step explanation:

Hope this helps!

Answer:

-15

Step-by-step explanation:

6x+15=8x+45

or,6x-8x=45-15

or,-2x=30

or,x=30/-2

or,x=-15

Let the length be 9x and width be 4x.

4x = 52

x = 13

Length = 9x = 117 mm

Answer:

(D) Jordan worked a total of 21 1/2 hours.

Step-by-step explanation:

Solution: m=money made

h=hours worked

m=$4(h)+$10

$96=$4(h)+$10 subtract the 10

$86=$4(h) divide by 4

21.5=h

Answer: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equation.

Answer:

8(x+2)=3

Step-by-step explanation:

Answer:

I believe the answer would be 24

Step-by-step explanation:

the sequence of the pool length is by 8's

72 + 8= 80

80 + 8= 88

88 + 8= 96

and the same goes to the width and it goes by 2's

18 + 2= 20

20 + 2= 22

22 + 2= 24
