Find the value of the unknown numbers

4 →  b

-1 →  e

-4 →  a

-5 →  c

Step-by-step explanation:

From the given figure, we can find the values of a,b,c,d and e

To find a

3 - a = 7

a = 3 - 7 = -4

To find b

-1 - b = -5

b = -1 + 5 = 4

To find c

4 - c = 9

c = 4 - 9 = - 5

To find d

3 - d = 1

d = 3 + 1 = 4

To find e

-1 - e = 0

e = -1

There for the correct matching is given below

4 →  b

-1 →  e

-4 →  a

-5 →  c

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

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
