Quadrilateral EFGH was dilated and rotated 90° clockwise about the origin to form

Mathematics
1 answer:
kirill [66]3 years ago
4 0

Answer:

<h2>Its angle measures.</h2>

Step-by-step explanation:

Notice that the transformations are a rotation and a dilation.

Rotations are rigid transformations, which only changes their position, but dilation changes their size.

That means, the final figure doens't have the same size or position as the original. The only things that remain the same are the angles, beacuse the final figure is similar to the initial, which means their angles are congruent.

Therefore, the right answer is the third choice.

Evaluate the polynomial when a.x=0 and b.x=-1<br> x2 – 3x - 7
Arlecino [84]

Answer:

a) -7 & b) -6

Step-by-step explanation:

Here,

a) x = 0

Solution ↦

x2 - 3x - 7 \\  =  0 \times 2 - 3 \times 0 - 7 \\  =  - 7

b) x = -1

Solution ↦

x2 - 3x - 7 \\  =  - 1 \times 2 - 3 \times ( - 1) - 7 \\  =  - 2 + 3 - 7 \\  =  - 9 + 3 \\  =  - 6

Melissa, Dan, and Henry have $87 in their wallets. Dan has 3 times what Henry has. Melissa has $8 less than Henry. How much does
puteri [66]

Answer:

Henry has $19, Dan has $57, and Melissa has $11

Step-by-step explanation:

Let x represent how much money Henry has

Since Dan has 3 times what Henry has, his amount is 3x

Since Melissa has $8 less than Henry, her amount is x - 8

Create an equation that sets these 3 values equal to 87, then solve for x

(x) + (3x) + (x - 8) = 87

5x - 8 = 87

5x = 95

x = 19

So, Henry has $19

Find how much Dan has by multiplying 19 by 3

19(3)

= 57

Find how much Melissa has by subtracting 8 from 19

19 - 8

= 11

So, Henry has $19, Dan has $57, and Melissa has $11
