The solution set for -2x2 + 12x = 0 is {0, 12} {0, -12} {0, 6} {0, -6} .

1 answer:

8 0

Hey Stephanie

-2x² + 12x = 0
Factor left side
2x(-x + 6) = 0
Now, we need to set factor equal to 0
2x = 0 or -x + 6 = 0
x = 0 or x = 6
The answer is : {0,6}

Good luck Stephanie :)

The equation of a straight line is an equation that comes in the form of an algebraic equation. It is also referred to as Slope - Intercept form. It can be represented using the equation below:

Equation : y = mx + c

where:

m = Gradient

c = Slope of the line

The equation that shows how the price of a personal pizza y, depends on the number of toppings x is y = 7 + x

This question can be solved and represented using the equation of a straight line.

Let's represent

y = price of a personal pizza

x = number of toppings

The price for a plain cheese pizza = $7

The price for each of the toppings = $1

Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x is written as:

y = $7 + $1 * x

y = 7 + x

A baker uses 131 2 cups of flour to make key lime bread. She uses 21 4 cups of flour to make each loaf. The baker sells 2 3 of t

elena-14-01-66 [18.8K]

Answer:

She sells 4 loaves of key lime bread

Step-by-step explanation:

Extracting the key information from the question:

*** A baker uses 13 1/2 cups of flour to make key lime bread

*** She uses 2 1/4 cups to make each loaf.

*** She sells 2/3 of the loaves of bread that she makes.

Now, since she uses 2 1/4 to make each loaf, we will convert this into improper fraction.

2 1/4 = [(4×2)+1]/4 = 9/4

She uses a total of 13 1/2 cups of flour to make all loaves.

To find the number of loaves she makes, we will divide the overall quantity of flour used by the quantity used to make a loaf

13 1/2 ÷ 2 1/4

Since 13 1/2 and 2 1/4 are the same as 27/2 and 9/4 respectively (mixed to improper fractions), we will then divide 27/2 by 9/4

= 27/2 × 4/9 = 6 loaves (total bread she makes).

Again, we learnt she sells 2/3 of the total loaves she makes.

Since total = 6, then 2/3 of 6 is:

2/3 × 6 = 4 loaves .

Therefore, the baker sells 4 loaves of key lime bread.

Use the dot plot to answer the question.

Tcecarenko [31]

Answer:

Mean of the data set in the dot plot would be: 3.6

Step-by-step explanation:

As we know that Mean from the dot plot can be obtained by:

adding the numbers and then
divide the resulting sum by the number of addends.

Please check the attached figure where the dot plot is also plotted.

From the dot plot, it is clear that

There are 3 dots at 1.

There are 4 dots at 2.

There are 3 dots at 3.

There are 4 dots at 4.

There are 5 dots at 5.

There are 3 dots at 6.

All we have to do is to add the dots and divide the sum by the number of addend dots.

In other words:

There are 3 dots at 1 ⇒ 1+1+1

There are 4 dots at 2 ⇒ 2+2+2+2

There are 3 dots at 3 ⇒ 3+3+3

There are 4 dots at 4 ⇒ 4+4+4+4

There are 5 dots at 5 ⇒ 5+5+5+5+5

There are 3 dots at 6 ⇒ 6+6+6

As there are total 22 dots.

And the sum of all the dots with respect to their plot number = 79

i.e. 1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6 = 79

Thus

Mean of the data set in the dot plot = 79/22

= 3.6

Therefore, Mean of the data set in the dot plot would be: 3.6
