Help please, I need the answer fast.

C

Step-by-step explanation:

This is a rate of change question, and given the two coordinates, the slope needs to be calculated

Calculate slope (m) with this formula: (y2-y1)/(x2-x1)

the points are (2,41) and (3,59.25)

we can label the points

x1=2

y1=41

x2=3

y2=59.25

now substitute into the equation

m=(59.25-41)/(3-2)

m=18.25/1

m=18.25

So the answer is C

Hope this helps!

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
