Hello! I believe you are referencing to powers of 10. In this case 10^2 is 100. 5.6 * 100 = 560. Okay. We are looking for the expression that will give the solution that is 100,000 times greater than 560. Okay. 100,000 * 560 is 56,000,000. That is 56 million. In this case, 10^7 is equivalent to 10,000,000, because there are 7 zeros behind the 1. 5.6 * 10^7 is 56,000,000. There. 56 million is 100,000x greater than 560. The answer is B.

Determine the intercepts of the line.
iogann1982 [59]

Answer:

y-intercept: (0,5)

x-intercept: (5/2,0)

Step-by-step explanation:

-4x+7=2y-3

-4(0)+7=2y-3

0+7=2y-3

7=2y-3

10=2y

5=y <-- y-intercept: (0,5)

-4x+7=2y-3

-4x+7=2(0)-3

-4x+7=-3

-4x=-10

x=\frac{5}{2} <-- x-intercept: (5/2,0)

50,000 - 5,000 = 45,000
