(48p+24) / 6
Solve using Distributive property

Answers

Answer:

8p + 4

Step-by-step explanation:

(48p + 24) / 6

We will first divide the first term, 48p

48/6 = 8, so 48p/6 = 8p.

24/6=4

That makes our final expression:

Identify an equation in point-slope form for the line perpendicular to y = -1/2x + 11 that passes through (4, -8)

Answers

Answer:

y+8 = 2(x-4)

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.

And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:

y-y1 = m(x-x1)

Cedro bought 10 ounces of Cereal A for $2.25. Then he bought 15 ounces of Cereal B for $3.30. Which cereal is less expensive?

Answers

Answer:

Cereal B.

Step-by-step explanation:

To figure out how much it costs per ounce for each cereal, first we need to divide.

Cereal A: $2.25 / 10 = $.225 per ounce

Cereal B: $3.30 / 15 = $.22 per ounce

So, cereal B is less expensive.

The equation representing the right table is

The solution to the system of equations is

Answers

Answer:

The equation representing the left table is:  

y = 1.5x – 6

The equation representing the right table is:  

y = –4x + 6.1

The solution to the system of equations is:  

(2.2, –2.7)

Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The first table is

x            y

0           -6

1            -4.5

2            -3

3             -1.5

Slope = -4.5+6/1

=1.5

Now let us find y intercept

-6=1.5(0)+b

-6=b

So the equation representing the left table is y=1.5x-6

Now let us find second table

x            y

0           6.1

1             2.1

2           -1.9

3            -5.9

m=2.1-6.1/1=-4

Now y intercept

2.1=-4+b

b=2.1+4

b=6.1

Equation representing the right table is y=-4x+6.1

Now equate two equations

1.5x-6=-4x+6.1

1.5x+4x=6.1+6

5.5x=12.1

x=12.1/5.5

x=2.2

and y=-4(2.2)+6.1

y=-8.8+6.1

y=-2.7

Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Step-by-step explanation:

A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

days

Part B
Which explains how to find the number of days it will take Morgan to finish her book using Plan B?
Select all that apply.
A.


Multiply 20 × 16 to get 320, which is not enough days. So multiply 20 × 17 to get 340, which is enough days.
B.


Since 20 pages is halfway between 10 and 30 pages, the number of days must be halfway between 33 and 11 days.
C.


Since 10 pages are added each day from Plan A to Plan B, 10 days must be subtracted from the number of days needed in Plan A.
D.

Five-sixths of the boats in the marina are white, 2 5 of the remaining boats are blue, and the rest are red. If there are 12 red boats, how many boats are in the marina?

Answers

Answer: There are 120 boats in the marina.

Step-by-step explanation:

Let's suppose that there are N boats

We know that 5/6 of them are white, then we have: (5/6)*N white boats.

The remaining is: N - (5/6)*N = (1/6)*N

We know that 2/5 of the remaining are blue, then we have:

(2/5)*(1/6)*N blue boats

And the rest are red, the rest is:

(1/6)*N - (2/5)*(1/6)*N = (3/5)*(1/6)*N

Then we have (3/5)*(1/6)*N red boats.

And we know that there are 12 red boats, then:

(3/5)*(1/6)*N = 12

Now we can solve this for N, which is the total number of boats in the marina.

N = 12*(6)*(5/3) = 120

There are 120 boats in the marina.

Step-by-step explanation:

Step 1: Define

Step 2: Solve for n

[Addition Property of Equality] Add 4 on both sides:                                   2(n + 3) < 10[Division Property of Equality] Divide 2 on both sides:                                n + 3 < 5[Subtraction Property of Equality] Subtract 3 on both sides:                       n < 2

Here we see that any value n smaller than 2 would work as a solution to the inequality.
