Answer:

He is wrong since reflecting the image across the x-axis means reflecting it on the axis that is horizontal and reflecting it over the y-axis means reflecting it on the y-axis which is verticle.

Answer:No, it would not be the same if you reflect it from the X axis.

Step-by-step explanation:

because the the shape is not "on" the X axis. When you reflect the shape across the X axis, then you will not really get a shape. It's easier if you imagine you put a mirror on the x axis and looked at it. Malik would have to shift the whole shape down so that the current points (3,1) and (-3,1) would change to (3,0) and (-3,0) Also shifting down the other two points too. Reflecting it is like if you had the shape in paper and you folded it in half. If it matches perfectly, then you know that you have a match and that it is reflecting. If it doesn't fold perfectly, then it doesn't reflect. So if you folded the shape from the X axis, you wouldn't get a perfect match so he is wrong. Does it help?

Fast forward a few years...and suppose you need to get your car repaired. You see the ads above. Your father, who knows a bit ab

katovenus [111]

Mikes repair shop $100 service charge plus $65 per hour Amys auto repair $40 service charge plus $80 per hour write an equation for each repair shop to represent the total cost of a car repair as a function of the number of hours worked let C = total cost to you let h = number of hours worked. Suppose you need to get the dent in your car repaired you see the ads above in the newspaper your father who knows a bit about cars said it would take no more than 3 hours for the repair person to fix your car how do you determine where you should take your car to get it repaired

-Mike Cost:: M(3) = 100 +65*3 = $295

-Amy Cost:: A(3) = 40 + 80*3 = $280

------------------------------------------------------------

-Mike charges 100 dollars service charge plus 65 dollars per hour.

-Amy charges 40 dollars service charge plus 80 dollars per hour.

-The cost to repair from mike is 100 + 65 * x.

-The cost to repair from amy is 40 + 80 * x.

------------------------------------------------------------

Let x = 3 and you get:

The cost to repair from mike is 100 + 65 * 3 = 295 dollars.

The cost to repaid from amy is 40 + 80 * 3 = 280 dollars.

As long as the time to repair is 3 hours or less, the cost to repair will be cheaper from Amy.

Determine the area of the shaded region. Use 3 for pi.

IrinaK [193]

Answer:

The area of the shaded region is 294 square inches ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- From the attached figure

- There are two congruent circles inscribed in a circle

∵ The two congruent circles touch each other at one point and

each one touch the big circle at one point

∴ The centers of the three circles and the touches' points lie on

the same segment which is the diameter of the big circle

∴ The diameter of the big circle = the sum of the diameters of the

inscribed circles

∵ The radii of the congruent circle = 7 inches

∵ The diameter of a circle is twice its radius

∴ The diameter of each inscribed circle = 2 × 7 = 14 inches

∴ The diameter of the big circle = 14 + 14 = 28 inches

∵ The radius of a circle is half its diameter

∴ The radius of the big circle = 1/2 × 28 = 14 inches

- The area of the shaded part is the difference between the area

of the big circle and the sum of areas of the congruent circles

∵ The area of a circle = πr²

∵ The radius of the big circle is 14 inches

∵ π = 3 ⇒ given

∴ The area of the big circle = 3(14)² = 588 inches²

∵ The radius of each congruent circle is 7 inches

∴ The area of each congruent circles = 3(7)² = 147 inches²

∴ The area of the two congruent circles = 2 × 147 = 294 inches²

∵ Area shaded = area big circle - area two congruent circles

∴ Area shaded = 588 - 294 = 294 inches²

* The area of the shaded region is 294 square inches

shtirl [24]

Answer:

6p + 4d = 36

Step-by-step explanation:

If p = number of pins and d = number of major decisions, then the equation is 6p + 4d = 36.

Hope this helps!
