Answer:
y = 15x + 20 or 15x - y + 20 = 0
x = 11
Step-by-step explanation:
Line is passing through the points (0, 20) & (2, 50)
Slope of line = (50 - 20)/(2 - 0) = 30/2 = 15
Equation of line
y - 20 = 15(x - 0)
y - 20 = 15x
y = 15x + 20 or 15x - y + 20 = 0
Plug y = 185 in above equation, we find:
185 = 15x + 20
185 - 20 = 15x
165 = 15x
x = 165/15
x = 11
If 6 also had the -2 exponent answer would be D if not then A
the 5 is in the hundreds place, the 7 is in the tens place and the 2 is in the ones place
7^0=1
7^1=7
7^2=7*7=49
7^3=7*7*7=343
etc... etc...
