Answer:

Step-by-step explanation:

10x - 15y = 21

15y = 10x - 21

y = ⅔x - 7/5

slope of line is ⅔

slope of any perpendicular to line is -3/2

y = kx + k

slope of line is k

k = -3/2

Rearrange the equation so u is the independent variable. -12u+13=8w-3 <br><br> w= ___
Rama09 [41]

Answer:

w = \frac{-12u+16}{8}

Step-by-step explanation:

Reverse the equation placing w on the left side

8w - 3 = - 12u + 13 ( add 3 to both sides )

8w = - 12u + 16 ( divide both sides by 8 )

w = \frac{-12u+16}{8}

The figure shown is a rectangle. If you draw a new rectangle in which the dimensions are doubled, what is the relationship betwe
stellarik [79]

Answer:

Step-by-step explanation:

Givens

L = 5

w = 3

Formula

Area = L*w

Solution

Area = 3 * 5

Area = 15

Now double both the width and the Length.

New Length = 2*5 = 10

New Width = 2 * 3 = 6

Area = New Length * New Width

Area = 10 * 6

Area = 60

Answer (look at the choices)

The old rectangle has an area of 15. The new Rectangle has an area of 60. If you double 15, do you get 60. No, so the answer is not A

The new rectangle is 60. If you halve it, do you get 15. No so the answer is Not B

C is the answer

D is you multiply 8 * 15, do you get 60? No so the answer is not D
