How does the graph of this function compare with the graph of the parent function, y=1/x? It is shifted right 5 units and up 2 u
nasty-shy [4]

Answer:

It is shifted left 5 units and up 2 units from the parent function.

Step-by-step explanation:

Given

y = \frac{1}{x}

y' = \frac{1}{x+5} + 2

Required

Compare both functions

First, translate y, 5 units left.

The rule is:

(x,y) \to (x + 5,y)

So, we have:

y = \frac{1}{x}

y_1 = \frac{1}{x + 5}

Next, translate y1, 2 units up.

The rule is:

(x,y) \to (x,y+2)

So, we have:

y' = y_1 + 2

y' = \frac{1}{x + 5} + 2

Hence, the transformation is:

5 units left and 2 units up

Wally had two more marbled than ashan and together they have 88 marbles how many marbles does ashan have
labwork [276]
Represent as
w=wally
a=ashan
so wally has 2 more marbles than ashan
w=2+a

together they have 88
w+a=88

since w=2+a, subsitute (2+a) for w in the w+a=88 equation
2+a+a=88
add like terms
2+2a=88
subtract 2 from both sides
2a=86
divide by 2
a=43

ashan has 43 marbles
