How do you graph the inequality of x ≤ -2 on a number line? And is it an open circle or closed?

The correct transformation rule to translate points two units up and four units to the left is,

(x, y) → (x - 4, y + 2)

We have to given that,

Erin made a mistake when writing a transformation rule to translate points two units up and four units to the left.

Here, Transformation Rule:

(x, y) → (x + 2, y - 4)

Since, We know that,

The correct transformation rule to translate points two units up and four units to the left is,

(x, y) → (x - 4, y + 2)

As, for 2 units up we add 2 in y - coordinate and 4 units left we subtract 4 in x - coordinates.

Answer: The brother drove 6 hours and the sister drove 5 hours of the trip

Step-by-step explanation:

Your brother drove 35 miles, and your sister drove 600 miles.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have the following system of equations:

x + y = 11                ....(i)

60x + 55y = 635  ....(ii)

Using the elimination method:

Multiply equation 1 by 55, equation 2 by -1, and add both equations together:

55x + 55y = 605, -60x - 55y = -635

Simplify and solve for x: -5x = -30

x = 6

Substitute this value of x back into equation 1 to find y:

y = 11 - 6 = 5

Thus, your brother drove 35 miles, and your sister drove 635 - 35 = 600 miles.

Answer:

yes

Step-by-step explanation:

to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-

81*2/9=18

900*2/9=200

72*2/9=16

72*2/9=16

450*2/9=100

now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true

good luck :)

Answer:  C.) x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit. Is not the answer

Step-by-step explanation: I took the test and got it wrong. I don't know what the answer is.

x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that a local gym sells monthly memberships. The function f(x) = −x² + 18x − 72 models the daily profit in dollars.

The given quadratic equation is solved by equating the function to zero:-

−x² + 18x − 72 = 0

x² - 18x + 72 = 0

x² - 12x -6x + 72 = 0

x ( x -12 ) -6 ( x -12 )= 0

( x - 12 ) ( x - 6 ) =0

x = 12, 6

Therefore, x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.

The total percentage increase in the investor's stock account will be 8.6%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The amount he earned from company A and company B is given as,

Earned = $5660 x 0.05 + $2500 x 0.09

Earned = $283 + $225

Earned = $508

Then the total percentage increase in the investor's stock account is given as,

P = [(508) / (5660 + 2500)] x 100

P = (508 / 5910) x 100

P = 0.086 x 100

P = 8.6%

The total percentage increase in the investor's stock account will be 8.6%.

The number of storybooks owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8. The mean is 8 and Absolute Deviation= 0.

The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The number of storybooks owned by eight classmates is shown below:

8, 9, 9, 7, 8, 6, 9, 8

Part A:

[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]

Therefore, The mean is 8

Part B: Absolute Deviation= 0  

subtract each number by the mean

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

(then divide sum by mean) 0 divided by 8 = 8

Answer:

0.3

Step-by-step explanation

The formula to find density is m/v=p

m=mass

v=volume

p=density

All we have to do is plug in 6g and 20cm^3

This will give us 6/20 which simplifies to 3/10

With this you can easily figure out that the decimal for 3/10 is 0.3

So the density of the ice is 0.3

Answer:

1. 116 m

2. 60 cm

Step-by-step explanation:

1. The total area is 12*10 m, or 120 m. The area of the non-shaded region is 7*2 m, or 14. Subtract 14 from 120 to get 116.

BTW the side 12 looks like it is less than the 10, the question is not lengthed properly, just saying

2. A bit trickier, divide the question into 2 parts, a triangle and rectangle.

The rectangle is 12*4 cm, or 48 cm, the triangle is 12 - 3 - 3 = 6 and 8 - 4 = 4

So we use 6 and 4. The area of a triangle is 1/2b * h, half of the base times the height, the base is 6 cm, and the height is 4 cm, 1/2(6) * 4 = 3*4 = 12 cm

48 + 12 = 60 cm

Answer:

$38.50 per hour

Step-by-step explanation:

10% = 0.1

0.1 × 35.00 = 3.50

35.00 + 3.50 = 38.50

Answer:

The answer is $38.50

Step-by-step explanation:

35 x 0.1 = 3.5 (0)

35 + 3.50 = 38.50

The reason we do 0.1 is because 10% written in decimal form is 0.1 and since 35.00 is a decimal we made the percent into a decimal to make it even.
