For f(x+h) - \dfrac{f(x)}{h} reading the fraction like f(x)/h only (f(x+h) start fraction f(x) / h end fraction), the answer is -x^2/y + x^2 + 2x + y + y^2 - 1/y + 1

He coordinates of the vertices of △DEF are D(2, −1) , E(7, −1) , and F(2, −3) .
miv72 [106K]
Given that th<span>e coordinates of the vertices of △DEF are D(2, −1) , E(7, −1) , and F(2, −3) and the coordinates of the vertices of △D′E′F′ are D′(0, −1) , E′(−5, −1) , and F′(0, −3) .

Notice that the y-coordinates of the pre-image and that of the image are the same, which means that there is a reflection across the y-axis.

A refrection across the y-axis results in the change in sign of the x-coordinates of the pre-image and the image while the y-coordinate of the image remains the same as that of the pre-image.

A refrection across the y-axis of </span>△DEF with vertices D(2, −1) , E(7, −1) , and F(2, −3) will result in and image with vertices (-2, -1), (-7, -1) and (-2, -3) respectively.

Notice that the x-coordinate of the final image △D′E′F′ with vertices <span>D′(0, −1) , E′(−5, −1) , and F′(0, −3) is 2 units greater than the vertices of the result of recting the pre-image across the y-axis.

This means that the result of refrecting the pre-image was shifted two places to the right.

Therefore, </span>the sequence of transformations that maps △DEF to △D′E′F′ are reflection across the y-axis and translation 2 units right.

Simplify (4/5)^-2. Show your work!<br> PLEASE HELP ASAP! 40 POINTS!
Olenka [21]

Answer: (16/25)

Step-by-step explanation: That's -(4/5) x -(4/5) = (16/25). It's that answer because a negative times a negative equals a positive. The exponent in the problem is telling you to multiply -4/5 times itself 2 times.

How much would you need to deposit in an account now in order to have $4000 in the account in 15 years? Assume the account earns
Finger [1]

Answer:

$2500

Step-by-step explanation:

CA=p(1+MR÷1200)

4000=p(1+180×4÷1200) 15 yrs =15×12=180 month

4000=1.6p

p=4000÷1.6

p=2500

If a parallelogram has diagonals that are perpendicular bisectors of each other, what is the most descriptive name for it?
Feliz [49]
Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.
