Answer:
x= -3
y= -2
From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.
Answer:
31, 53,57,79,24,46,68
Step-by-step explanation:
13+18=31
35+18=53
57+18=75
79+18=97
24+18=42
46+18=64
68+18=86
The word decreased indicates that a negative internet should be used
If y is 7, x is 2. If y is 9, x is 4. Therefore the domain is {2,4}
Solution:
<u>Note that:</u>
- Triangle = 180°
- 5x + 130 + 3x + 2 = 180
<u>Simplify the equation to find x.</u>
- 5x + 130 + 3x + 2 = 180
- => 8x + 130 + 2 = 180
- => 8x + 2 = 180 - 130
- => 8x = 50 - 2
- => 8x = 48
- => x = 48/8 = 6
The value of x is 6.
