Answer:

C. A translation and a dilation

Step-by-step explanation:

Of course it has to be a dilation as the size is obviously different. So that takes D out of the question. The angles are in the same spots as B is still at the highest on both triangles and so does A. Which means it just translated (moved/slide) to the right and up a bit.

Yo im not good at this stuff, can someone help me?

Kazeer [188]

Answer:

21 kWh

Step-by-step explanation:

1. Subtract 25% from the original amount.

25% of 28 kWh is ...

0.25 × 28 kWh = 7.00 kWh

Subtracting this from 28 kWh, we find the usage after reduction to be ...

28 kWh - 7 kWh = 21 kWh

2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...

(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh

Mario must reduce his usage to 21 kWh or less.

Find the equation of this line.<br>HELP

Mumz [18]

Answer:

Step-by-step explanation:

(5,4) ; (-3, -2)

$Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-2-4}{-3-5}\\\\=\frac{-6}{-8}\\\\=\frac{3}{4}$

(5,4) & m = (3/4)

y -y1 = m(x-x1)

y - 4 = (3/4)(x - 5)

$y-4=\frac{3}{4}x-\frac{3}{4}*5\\\\y-4=\frac{3}{4}x-\frac{15}{4}\\\\y=\frac{3}{4}x-\frac{15}{4}+4\\\\y=\frac{3}{4}x-\frac{15}{4}+\frac{4*4}{1*4}\\\\y=\frac{3}{4}x-\frac{15}{4}+\frac{16}{4}\\\\y=\frac{3}{4}x+\frac{1}{4}$

Mauricio hits a baseball 4 times as often as Tony each game. He also hits 20 baseballs every Monday at practice. Tony hits 4 bal

yulyashka [42]

Tony will be x because they are comparing Mauricio to Tony so 4x+20 so then we know x=4 because it says Tony’s hits 4 balls on Saturday so 4x4+20 = 16+20= 36 balls hit by Mauricia
