Do a proportion. 28/100= 7/x. Now cross multiply and divide. 7 x 100=700 and 700 divided by 28 is 25. There are 25 students in the class. Answer is 25

Which choice shows the image of quadrilateral WXYZ after a reflection over the y-axis followed by a translation down 2 units?
max2010maxim [7]

Answer:

Choices are not provided, but you can answer the question as follows: take the coordinates of quadrilateral WXYZ and apply:

W(xW, yW) -> W'(-xW, yW-2)

X(xX, yX) -> X'(-xX, yX-2)

Y(xY, yY) -> Y'(-xY, yY-2)

Z(xZ, yZ) -> Z'(-xZ, yZ-2)

For example, if point W is located at (1, 1), W' would be located at (-1, -1)

Step-by-step explanation:

Reflection over the y-axis transforms point (x, y) into (-x, y)

Translation down 2 units transforms point (x, y) into (x, y-2)

You babysit 15 hours each week for $6.00 per hour. You also earn $25.00 each
alexdok [17]

Answer:

$115

Step-by-step explanation:

Although it did say to complete the equation I put the answer just in case.

So, in order to calculate the total weekly income, I will use x which will equal the number of hours. The equation needed to calculate the weekly total income will be:

w = 6x + 25

Because we know the number of hours is 15, we can plug 15 in x:

w = 6(15) + 25

w=90+25

w=115

So, the total weekly income will be $115(don't forget to put the unit! In this case it will be the dollar sign).

Lostsunrise [7]
From least to greatest: -10, -3, +1. From greatest to least: +1, -3, -10.
1st way: Just look at it.
2nd way: See which numbers are to the left of 0 on the number line. Those are your smaller (negative) numbers. The numbers that are on the right side of 0 are your bigger (positive) numbers.
