Consider the following two circles. Circle P with center (-1, 2) and radius 3 and circle Q with center (3, 4) radius 5. What sequence of transformations will carry circle P onto circle Q? Select all that apply.A. Dilation centered at Q, followed by reflection across the y-axis
B. Dilation centered at P, followed by reflection across the y-axis and then the line y = -x + 5
C. Translation (x,y) -> (x+4, y+2), followed by dilation centered at Q
D. Dilation (x+y) -> (3/5x, 3/5y), followed by dilation centered at P
E. Reflection over x-axis followed by rotation of 270 degrees

Answer 1
Answer:

Answer:

B. Dilation centered at P, followed by reflection across the y-axis and then the line y = -x + 5

Step-by-step explanation:

Circle P.

Centerat (-1, 2).

Radius of 3.

Circle Q.

Center at (3, 4).

Radius of 5.

To carry one circle onto the other, their centers and radius must be the same.

So, circle P must be shifted from (-1, 2) to (3, 4), that means the translation is 4 units to the right side and two units upside, this is the first transformation.

The second transformation must be about stretching the circle P, from a radius of 3 to a radius of 5.

Therefore, the right answer is B.

Step-by-step explanation:

To calculate the percent of tax on an item priced at $135, we need to find the percentage of $8.10 in relation to the original price.

To do this, we divide the tax amount by the original price and then multiply by 100 to find the percentage:

($8.10 / $135) * 100 = 0.06 * 100 = 6%

Therefore, the tax on the item priced at $135 is 6%.

If you are looking for the nearest whole percentage, it would be 6%

Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each. Which equation can be used to find the number of pies she needs to sell to break even?

Answers

We can represent the number of pies she makes to be x. We also need to add $30 to the equation to take the baking supply cost into consideration. The Cost can be represented by C. C = 5x + 30 is the equation to use to determine the Cost! 5 times the number of pies she makes plus the $30 for baking supplies! If we look at just the cost when she doesn't sell any pies, we can say x = 0 That means C = 5(0) + 30 or C = 30, it means that she has to pay $30 or the Cost is $30 when she sells no pies. This makes sense since the baking supplies were $30. Are you with me so far?

How do I solve this?

Answers

You have to find LCD (lowest common denominator) in this case it will be 5x:

(u)/(x)+(5u)/(x)- (u)/(5x)=(5*u)/(5x)+(5*5u)/(5*x)- (u)/(5x)=(5u+25u-u)/(5x)=(29u)/(5x)

Let's solve your equation step-by-step.7+x−15=223
Step 1: Simplify both sides of the equation.
x−8=8/3
Step 2: Add 8 to both sides
.x−8+8=8/3+8x=32/3

For the inverse variation equation xy = k, what is the constant of variation, k, when x = 7 and y = 3?A. 3/7

B. 7/3

C. 10

D. 21

Answers

Answer:

  D.  21

Step-by-step explanation:

The equation tells you xy = k. Substituting the given values, you get ...

  7·3 = k

  21 = k

Answer:

D) 21

Step-by-step explanation:

The given inverse variation equation is x.y = k, where k is the constant of proportionality.

Given: x = 7 and y = 3.

We need to find the constant variation, k.

To find the constant variation, k, plug in x = 7 and y = 3 in the given equation and simplify.

k = 7*3

k = 21.

Therefore, the constant of variation k = 21.

Answer is D) 21.
