12x² + 8x = 0
What are the zeroes?

Answer:

Step-by-step explanation:

h(x) = x² - 5x

x² - 5x = 104

x² - 5x - 104 = 0

D = (- 5)² - 4(1)(- 104) = 441 = 21²

[tex]x_{1}[/tex] = (5 - 21) / 2 = - 8

[tex]x_{2}[/tex] = (5 + 21) / 2 = 13

Answer:

D) [tex]1\frac{21}{40}m^2[/tex]

Step-by-step explanation:

We can first change the area of his garden into an improper fraction:

[tex]7\frac{5}{8} m^2 = \frac{61}{8}m^2[/tex]

Since Eric wants to split his garden into five equal sections, we divide the area of his garden by [tex]5[/tex]:

[tex]\frac{61}{8}\div 5 = \frac{61}{40}[/tex]

[tex]=1\frac{21}{40}m^2[/tex]

∴ The area of each new section is [tex]1\frac{21}{40}m^2[/tex]

Answer:

3/8 shortening, 1/4 t salt, 9/8 sugar, 3/4 baking soda, 1/8 eggs, 1 c. Cake flour, 1/4, vanilla extract, 1/8 butter flavoring

Step-by-step explanation:

Half all your fractions, by doubling the numerator and denominator, then deviding the numerator by 2.

The amount require for 1 and half dozens is

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Let's first list the data that we currently have. The number of ice creams is 5. It costs $125 for 5 ice creams.

Step1 :Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.

Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.

Given:

Shortbread Cookies Makes =3 dozen cookies

3/4 shortening

1/2 t salt

9/4 granulated sugar

3/2 t baking soda

1/4 eggs

2 c. cake flour

1/2 vanilla extract food coloring

1/4 butter flavoring

Above we have ingredients according to 3 dozen but we want to have ingredients for 1 and half dozen which is half of 3 dozen

So, we will just make half of the amount of above ingredients present

Shortbread Cookies Makes =1 and 1/2 dozen cookies

3/4 x 1/2 = 3/8 shortening

1/2 x 1/2 = 1/4 t salt

9/4 x 1/2 = 9/8granulated sugar

3/2 x 1/2 = 3/4t baking soda

1/4 x 1/2 = 1/8 eggs

2 x 1/2 =1 c. cake flour

1/2 x 1/2 = 1/4 vanilla extract food coloring

1/4 x 1/2 = 1/8 butter flavoring

Answer: 3 3/8

Step-by-step explanation:

We know that for example 2/4=4/8 so it is multiplied by 2. In this problem the fractions are 2 2/4 and 6 1/8. We are subtracting so you would first multiply the fraction that’s going to subtracted from the other fraction 2 3/4= 2 6/8. Now that we have our fractions we can subtract 6 1/8-2 6/8 this would leave us with 3.375 which is equal to 3 3/8.

Answer:

Length of the rectangular closet = 4 feet

Step-by-step explanation:

Area of his bedroom = 80 square feet.

The area of his bedroom = 10 times that of his rectangular closet.

Let x = area of his rectangular closet.

80 = 10 * x

80 = 10x

x = 80/10

= 8

x = 8 square feet

If the closet is 2 feet wide, what is its length?

Area of the rectangular closet = length × width

Let y = Length of the rectangular closet

8 Square feet = y feet × 2 feet

8 = 2y

y = 8/2

= 4

y = 4 feet

Length of the rectangular closet = 4 feet

Answer:

133.33333333 percent

the diffrence is 800

Step-by-step explanation:

[(1400 - 600) / 600] × 100%

= 1.3333333333 × 100%

= 133.33333333%

Answer:

133.33% increase

Step-by-step explanation:

This is a percent increase, and to solve for one you need to know the following formula

[tex]|\frac{new~value~-~original~value}{original~value}| *100[/tex]

Plugging it in;

New value = 1400

Old value = 600

[tex]|\frac{new~value~-~original~value}{original~value}|= |\frac{1400-600}{600}| = |\frac{800}{600}| = 1.333333333[/tex]

1.3333333 as a percent is

133.33%

So you have an increase of 133.33%

Step-by-step explanation:

Properties of Exponents

The property called Power to a Power shows us how to simplify expressions of the type:

[tex](x^n)^m=x^{n*m}[/tex]

Similarily the property called Power of a product simplifies expressions like:

[tex](x.y)^n=x^n.y^n[/tex]

The company mentioned in the question uses the expression

[tex](2x^3)^3[/tex]

millimeters per second to calculate the maximum capacity of a photocell with an area of x^3 square millimeters.

First, use the power of a product property:

[tex](2x^3)^3=2^3\cdot (x^3)^3[/tex]

Now use the power to a power property:

[tex](2x^3)^3=2^3\cdot x^{3*3}[/tex]

Operate:

Answer:

5/6x+4 1/6=y

Step-by-step explanation:

The equation to find a slope-intercept is mx+b=y

m=slope

x=x coordinates

y=y coordinates

b= y intercept

m=5/6

x=-1

y=-5

b=4 1/6

Y intercept:

5/6(-1)+b=-5

-5/6+b=-5

b=4 1/6

However, it asks for an equation of the line, not (-1,-5), so we only need to write m and b, but not x and y.

So: 5/6x+4 1/6=y
