The line segment is rotated 90 degrees counterclockwise about the origin to form C′D′. Which statement describes C′D′

Answer:3over1

Step-by-step explanation:

Answer:

3

Explanation:

The formula for the slope of a line is

[tex]\frac{ y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]

In this case, the y2 would be 5 and the y1 would be 2

so the numerator would be 3.

The x2 would be 4 and the x1 would be 3 so the denominator would be 1.

The answer is [tex]\frac{3}{1} = 3[/tex]

Answer:

Step-by-step explanation:

Answer:

  D

Step-by-step explanation:

We assume the rotation R is counterclockwise 60°.

__

The exponent on R is the number of times it is applied. That is, R² = R(R(figure)). So, the composition is equivalent to R^(2-4) = R^-2.

When the exponent of R is negative, it is essentially the inverse function. That is, applying the function R to the result will give the figure you started with. Equivalently, it is rotation in the other direction.

  [tex](\mathcal{R}^2\circ\mathcal{R}^{-4})(\text{figure})=\mathcal{R}^{-2}(\text{figure})=\text{figure rotated $120^{\circ}$ CW}[/tex]

The point 120° clockwise from B is D.

The desired image point is D.

Answer:

Equation: y=1.5x+4          Will total $10 after 4 hours

Step-by-step explanation:

Format: y=mx+b

y is total cost

m is per hour

b is starting cost

Equation: y=1.5x+4

After 4 hours, it will be $10 because:

10=1.5x+4

subtract 4 both sides

6=1.5x

divide 6 by 1.5

4=x

Hence the 4 hours answer

Step-by-step explanation:

-5 + 3 = -2  -5 is larger

5 + (-3) = 2   5 is larger

2 is larger than -2

Answer:

The negative signs were switched.

Step-by-step explanation:

Aaron claims the same answer could also be found by adding either –5 + 3 or –3 + 5.

What is the error in Aaron’s reasoning?

The commutative property is not true for addition.

The negative signs were switched.

The numbers are not in the correct order.

The associative property was used.

Answer:

-2

Step-by-step explanation:

-7 + 5.  This is an easy question, you see, you could do this the other way (+) 5 - 7 = ? || All you have to do is start on the number line, -7, and count five in the positive, or "not negative", direction.

Answer:

[tex]\sqrt{3600}[/tex] is rational

Step-by-step explanation:

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The answer of square root of 3600 is 60 which is not a decimal or an irrational number and therefore it's rational

Answer:

129°

Step-by-step explanation:

∠DCE = 75

∠ECF = 54

∠DCF = ∠DCE + ∠ECF

         = 75 + 54

        = 129°

Answer:

129

Answer:

x³ + 4x² - 31x - 70

Step-by-step explanation:

Step 1: Expand (x - 5) and (x + 2)

(x - 5)(x + 2) = x² + 2x - 5x - 10 = x² - 3x - 10

Step 2: Expand (x² - 3x - 10) and (x + 7)

(x² - 3x - 10)(x + 7) = x³ - 3x² - 10x + 7x² - 21x - 70 = x³ + 4x² - 31x - 70

Answer:

7 and 1/2 cups of water.

Step-by-step explanation:

Every 2 cups of rice, you need three cups of water. You make this equation, [tex]\frac{2}{3} \frac{5}{y}[/tex] and do cross multiplication to get 2y=15, divide that by two and end up with 7 1/2 cups of water.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given Ben's observations when the wait time is as advertised represented by the equation 2|x − 2| − 12 = 0, to get the times when the serving time is as advertised, relative to noon, we will calculate for the value of x in the equation;

Note that the modulus of the function |x-2| will return both positive and negative value.

For the positive value of |x-2|;

2|x − 2| − 12 = 0

2(x − 2) − 12 = 0

open the parenthesis

2x-4 - 12 = 0

2x - 16 = 0

add 16 to both sides

2x-16+16 = 0+16

2x = 16

x = 16/2

x = 8

For the negative value of |x-2|;

2|x − 2| − 12 = 0

-2(x − 2) − 12 = 0

open the parenthesis

-2x+4 - 12 = 0

-2x - 8 = 0

add 8 to both sides

-2x-8+8 = 0+8

-2x = 8

x = -8/2

x = -4

Hence the times when the serving time is as advertised, relative to noon are 8minutes and 4minutes

Step-by-step explanation:

[tex]m=\frac{rise}{run}=\frac{1+11}{1+3}=\frac{12}{4}=\boxed{3}[/tex]

The slope of the line would be 3.

Hope this helps.

Answer:

Slope = 3

Step-by-step explanation:

Let (x1,y1) = (-3,-11) and (x2,y2) = (1,1)

Slope = y2-y1/(x2-x1)

1-(-11)/(1-(-3) = 12/4 = 3
