Answer:
y = -4/3x -1
Step-by-step explanation:
y = slopex + y-int
We can find the slope -4/3 by going down 4 times to the level of the second point from the first point. Then we go to the right 3 times to get to the 2nd point.
y = -4/3x + b
The spot on the line where x is 0 will be the y-intercept
In this case it is -1
y = -4/3x - 1
Answer:
2x+22=42
Step-by-step explanation:
2x+22-22=42-22. which is 2x=20 divide both sides with 2,therefore the answer is 10
Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
Answer:
72
Step-by-step explanation:
0 < x < 1
Multiply the inequality by 100
0 < 100x < 100
0 < 72 < 100
