Answer:
B.) 990
Step-by-step explanation:
Here's another way of looking at it.
Make an equation representing the graph.
y = mx + b
to find m (slope) I used points (1,30) and (4,150) to get 40 as the slope.
y = 40x + b
to solve for b (y-intercept) I plugged in any point that I wanted in the corresponding place in the equation.
using (4,150)
150 = 40 (4) + b
using PEMDAS you find that b = -10
Then plug and chug to find the number of stamps for the 25th term.
y = 40(25) + -10 or y = 40(25) - 10
y = 990

Answer:
y = 3/4 + 3/2
Step-by-step explanation:
Slope = 3/4
Solve for y-int.
0 = 3/4(-2) + b
-3/2 + b = 0
b = 3/2
y = 3/4x +3/2
X=_____. Or x=_______
