Answer:
x = 5
Step-by-step explanation:
Ashley and Adam spent a total of 31 hours on their projects so: 3x+2+4x-6 = 31
3x+2+4x-6 = 31
7x-4 = 31
7x = 35
x = 5
Since y=-1 when x=0 and we can write the equation (we'll turn it into an inequality later) as y=mx-1 from y=mx+b by plugging (0,1) in. Next, y equals 2 when x=1, so we plug those in to get 2=m*1-1. Adding 1 to both sides, we get 3=m, making our equation y=3x-1 (since y and x stay variables). Lastly, we turn it into an inequality, It seems to be inclusive to the line, so it's either
3x-1≤y or 3x-1≥y. Finding a random point in the inequality (4, 1), we plug it in to get 12-1=11, which is clearly larger than 1, so we get 3x-1≥y.
No, he is not correct. 2^3 = 8 and 5^3 = 125, so 8•125 = 1,000. 10^9 = 1,000,000,000.
