In the xy-coordinate plane shown, line L passes through point C and has a slope of -2. A dilation of line L with center A and a

a_sh-v [17]

Answer:

Step-by-step explanation:

Dilation of a line about a point not on the line shifts the line but leaves the slope intact .

New line slope will be -2

As both A and C lie on a horizontal line y = 2, C' will also lie on the same line

The distance between A and C is 0 - 2 = -2

a scale factor of 3 means C' is -2(3) = -6 units left of A

C' = (2 - 6, 2) = (-4. 2)

Is the length of the hypotenuse of a right triangle with legs that measure 5 cm and 6 cm a rational number or an irrational numb

Brut [27]

Answer:

irrational

Step-by-step explanation:

Use the Pythagorean theorem.

5² + 6² = c²

25 + 36 = c²

c² = 61

7² = 49

6² = 64

61 is between 7² and 8², so it is not rational.

Question 4. In the graph, lines f and g intersect at P(6,6). What is the area, in square units, of the shaded region? * E. 15 F.

erastova [34]

Answer:

E

Step-by-step explanation:

i guess the dotted lines outline a square

so get the area of the square which is 6×6=36

then don't focus on the shaded part but unshaded you'll see two right angled triangles

$a = 1 \div2b \times h$

you will get a total for both as 21

then get the area of the square 36-21=15

so the area becomes 15

Which of the following sets of points are vertices of a right triangle?

grandymaker [24]

Please find the picture for your triangle.
We know, area of a ∆ = <u>1/2 × base × height</u>
Here, base = ( 1 + 7 ) units = <u>8 units</u>
Height = ( 7 - 1 ) units = <u>6 units</u>
Therefore, area of the ∆
= <u>(1/2 × 8 × 6) square units</u>
= <u>24 square units.</u>

<u>Answer</u><u>:</u>

<em><u>2</u><u>4</u><u> </u><u>square </u></em><em><u>units</u></em>

Hope you can get an idea from it.

Carry on learning.
