I’m struggling and I need help

Step-by-step explanation:

f(x) = 5x +4

f(10) = 5*10 + 4

      = 50 +4

      = 54

f(13) = 5*13 + 4

       = 65 + 4

       = 69

f(19) = 5*19 + 4

      = 95 + 4

     = 99

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
