You would plug it in, so where there is a y in the first equation you will plug in the second equation, so it would become 3x+2(x-3)=9 and then solve. First you would distribute and get 3x+2x-6=9, then combine like terms and get 5x-6=9, then add 6 to both sides and get 5x=15, then divide both sides by 5 and get x=3
The answer is x=3
Answer:
y = x + 15
Step-by-step explanation:
okay so you're gonna use the y2-y1/x2-x1 formula to find the slope (m)
24 - 19/9 - 4 = 5/5 = 1
so that is your slope (m)
and now if you follow your slope then you should get your y-intercept (b)
4 - 1 = 3 19 - 1 = 18
(3, 18)
3 - 1 = 2 18 - 1 = 17
(2, 17)
2 - 1 = 1 17 - 1 = 16
(1, 16)
1 - 1 = 0 16 - 1 = 15
(0, 15)
so thats your y-intercept (b)
and the equation will look like:
y = mx + b y = x + 15 or y = 1x + 15 (but the 1 isn't necessary)
2+3x>=15 ................
25.9 divided by 7.4 is 7/2 which is 3.5 :)
