Okay well the relationship from 2 and -6 is multiplication by -3. SO if we apply that to -4, y will equal 12.
(2, -4)
(-6, 12)

RideAnS [48]

Answer:

Step-by-step explanation:

Somebody plays 30 times

L+W = 30, where L and W are number of losses and wins, respectively.

L = 30-W

Net after 30 plays is $6

2W - 1L = 6

2W - (30-W) = 6

3W = 36

W = 12

W = 18

17 wins

If ∠C and ∠D are vertical angles and m ∠ C = x + 5 and m ∠ D = –2x + 80, what is m ∠ C?

amm1812

Answer:

m∠C=30°

Step-by-step explanation:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always equal

m∠C=m∠D

substitute the given values

$(x+5)\°=(-2x+80)\°$

Solve for x

$x+2x=80-5\\3x=75\\x=25$

Find the measure of angle C

m∠C=(x+5)°

substitute the value of x

m∠C=(25+5)=30°
