Brooke is evaluating her college credit hours. In order to graduate, Brooke must complete at least 132 credit hours. She has already completed 4 semesters, receiving 15 credit hours per semester. Which inequality could be used to find c, the number of credit hours that Brooke needs to complete in order to graduate college? A. 4(15) + 4c > 132 B. 4(15) + c > 132 C. 4(15) + c < 132 D. 4(15) + 4c < 132

Step-by-step explanation:

  We already establish an understand  that, for Brooke to graduate she needs nothing less than 132 credit hours.

Now a semester has 15 credit hours, she has 4 semester completed already.

Hence 15*4= 60 credit hours done and dusted

This means that she has 132-60 = 72 credit hours to go

Since "c" is the number of credit hours that Brooke needs to complete in order to graduate college.

The inequality can be modeled as,

60 + c > 132

c= 132-60

c= 72

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
