(4x-6)+(8x+18)=180(adjacent angles are supplementary)
4x-6+8x+18=180
4x+8x-6+18=180
12x+12=180
12x=180-12
12x=168
x168/12
x=14
8x+18=y+3 (corresponding angles are equal)
8×14+18=y+3
130=y+3
-y=3-130
-y=-127
y=127
x=14, y=127
Answer:
False, since x values cannot have more than one y value.
Step-by-step explanation:
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
The domain of the equation are all the possible values of the independent variables that would make the equation reasonable, possible or true. In this item, the independent variable is r. This could take a value of 0 up to the point when m is equal to zero.
m = 30 - 3r = 0
r = 10
The domain is therefore [0, 10].
The range is the value of the dependent variable which would be from 0 to the point when no video game is played. This is, [0, 30].
The function is discrete because r and m cannot take every value in the number line.
