Answer:
x = 165, y = 15
Step-by-step explanation:
1. Well, what does supplementary mean? - The angles add up to 180°.
2. Let's form an equation: x + y = 180°
3. Let's say x is the larger angle and y is the smaller angle.
4. Let's form another equation: x = 150 + y
5. Put the two equations next to each other:
x + y = 180
x = 150 + y
6. We know what x is equaled to, so let's plug it into the first equation!
150 + y + y = 180
150 + 2y = 180
-150 -150
2y = 30
y = 15
7. Now, we know what y is, let's find x!
x + 15 = 180
-15 -15
x = 165
Answer:
no entiendo nada eso es inglés y pus yo no lo entendo
Answer: y=24
Explanation:
start by adding the two expressions
7y+12=180
7y=168
168/7
y=24
Plug it in/Check your work:
3(24)+5=77
4(24)+7=103
77+103=180
Answer:
h(-8)=1 and -12
Step-by-step explanation:
In this problem, we will need to plug in "-8" for any x we see.
h(-8)=|-8+4|-3
h(-8)= |-4|-3
h(-8)=4-3
h(-8)=1
Yay! We got an answer. However, since there is an absolute value, there is another case -- if x is negative.
h(-8)=-8-4
h(-8)=-12
