0<5xb<5 divide all terms by 5
0<xb<1 divide all terms by x
0<b<x
If you meant 5b as in 5*b then:
0<5b<5 divide all terms by 5
0<b<1
b is infinitely many values between 0 and 1.
Using the x and y intercepts from the graph to find the slope of the line:
slope = (0 - 2) / (4 - 0)
slope = -1/2
Using the point-slope form:
y - 0 = -1/2 (x - 4)
-2y = x - 4
4 = x + 2y
Coefficient of x is 1 and coefficient of y is 2.
Answer:
About 145 miles.
Explanation:
Assume that the distance from the center of the earth to any point on the earth's surface is 4,000 miles.
Step-by-step explanation:

4 is not a factor of 30 because the factor of 30 is:
2*15
6*5
3*10
1*30
1 7/6 divided by 1 3/5 = 5/5 as a reduced fraction!
