Step-by-step explanation:

using the distributive property we can multiply -2 to the numbers inside the parentheses.

-2w-2

Answer:

-2w-2

Step-by-step explanation:

−2(w+1)

=(−2)(w+1)

=(−2)(w)+(−2)(1)

=−2w−2

Explanation:

Subtract y from both sides. This will isolate y.

2y < y+2

2y-y < y+2-y ... subtract y from both sides

y < 2

The solution involves any number smaller than 2.

Answer:

25%

Step-by-step explanation:

8/32=1/4=0.25

The complete sentence with correct number is,

⇒ 8 is 25% of 32.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

To find 8 is what percent of 32.

Let 8 is x percent of 32.

Now, We can formulate;

⇒ x% of 32 = 8

Solve for x;

⇒ x/100 × 32 = 8

⇒ 32x = 8 × 100

⇒ 32x = 800

⇒ x = 800 / 32

⇒ x = 25

Thus, The complete sentence with correct number is,

⇒ 8 is 25% of 32.

3 wholes, each person gets 3/5 of a loaf

Step-by-step explanation:

They have 3 loaves of bread. If you divide each loaf into 1/5s you get a total of 15/5. 15/5 divided by 5 = 15/25 = 3/5 of a loaf each.

There are 5 people in Edgar's family. They have 3 loaves of pumpkin bread to share equally. 3/5 of a loaf each needed for the model.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

There are 5 people in Edgar's family. They have 3 loaves of pumpkin bread to share equally.

The greatest common factor (GCF) of 20 and 24 is 4, by using both methods which are Listing Factors and  Prime Factorization.

What is the Prime Factorization method?

Divide the given number by the smallest prime number. In this case, the smallest prime number should divide by the number exactly. Step 2: Again, divide the quotient by the smallest prime number. Step 3: Repeat the process, until the quotient becomes 1.

To find the greatest common factor (GCF) of 20 and 24, we can use the following methods:

Method 1: Listing Factors

List the factors of 20: 1, 2, 4, 5, 10, 20

List the factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Find the largest factor that both numbers share: 4

Therefore, the GCF of 20 and 24 is 4.

Method 2: Prime Factorization

Find the prime factorization of each number: 20 = 2 x 2 x 5, 24 = 2 x 2 x 2 x 3

Identify the common prime factors: 2 x 2 = 4

Therefore, the GCF of 20 and 24 is 4.

Either method shows that the greatest common factor of 20 and 24 is 4.

Answer:

Step-by-step explanation:

Let p and s represent the costs of plain and shiny rolls of paper, respectively. The given sales let us write two equations in these two unknowns.

  12p +1s = 59 . . . . . DeShawn's sale

  6p +8s = 112 . . . . . Tatsakan's sale

Multiplying the second equation by 2 and subtracting the first, we have ...

  2(6p +8s) -(12p +s) = 2(112) -(59)

  15s = 165 . . . . . . . . . . . . . . . . . . . . . simplify

  s = 11 . . . . . . . divide by 15

Substitute into the second equation to find p.

  6p +8(11) = 112

  6p = 24 . . . . . . . . subtract 88

  p = 4 . . . . . . . . . . .divide by 6

A plain roll costs $4; a shiny roll costs $11.

Answer:

y = 1/3x

Step-by-step explanation:

If you use the form y = mx + b, all you need to create a parallel line is to have the same slope. So, we can just disregard b and write an equation with a slope of 1/3. You can add or subtract any number to that if you want.

Answer:

The equation of the parabola in vertex form is [tex]x-6 = \frac{1}{16}\cdot (y-6)^{2}[/tex].

Step-by-step explanation:

Since the directrix is of the [tex]x = a[/tex], then the equation of the parabola in vertex form is of the form:

[tex]x-h = \frac{1}{4\cdot p}\cdot (y-k)^{2}[/tex] (1)

Where:

[tex]x[/tex] - Dependent variable.

[tex]y[/tex] - Independent variable.

[tex]p[/tex] - Least distance between focus and directrix.

[tex]h[/tex], [tex]k[/tex] - Coordinate of the vertex.

The least distance between focus and directrix is determined by Pythagorean Theorem:

[tex]p = \sqrt{(8-4)^{2}+(6-6)^{2}}[/tex]

[tex]p = 4[/tex]

Now, we determine the location of the vertex by the following vectorial formula:

[tex](h,k) = F(x,y) - (0.5\cdot p, 0)[/tex] (2)

If we know that [tex]p = 4[/tex] and [tex]F(x,y) = (8,6)[/tex], then the location of the vertex is:

[tex](h,k) = (8,6) -(2, 0)[/tex]

[tex](h,k) = (6,6)[/tex]

And the equation of the parabola in vertex form is [tex]x-6 = \frac{1}{16}\cdot (y-6)^{2}[/tex].
