Answer:

F(x) = 2^{x+2} - 6

Step-by-step explanation:

To shift a function F(x) a units to the left, we do:

F(x) = F(x+a)

In this problem, we have that:

F(x) = 2^{x}

So, shifting 2 units left:

F(x) = 2^{x+2}

Then

To shift a units down, we do:

F(x) = F(x) - a. So[tex]F(x) = 2^{x+2}

Shifting 6 units down

F(x) = 2^{x+2} - 6

The perimeter of a triangle is 42 yards. The first side is 5 yards less than the second side, and the third side is 2 yards less
Maru [420]
Let the second side be equal to x Then the first side is x-5 The third side will be x-5-2 = x-7 Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42 3x=44 X= 44/3 Therefore the second sides length is 44/3 The first sides length is 44/3 -5 = 29/3 The third side is 44/3 -7 = 23/3

Andy is collecting pocket change for a fundraiser. he begins with 102 coins in the cup, and their monetary value is $17.10. if h
Ira Lisetskai [31]

If Andy has 102 coins mixed with dimes and quarters and monetary value of $17.10 then he has 56 dimes and 42 quarters.

Given number of coins Andy has is 102 and montary value of all coins is $17.10.

We have to determine number of dimes and quarters.

1 dime=$0.10

1 quarter=$0.25

Suppose the number of dimes be x and number of quarters be y.

The equations are:

0.10x+0.25y=17.10------------1

x+y=102-------------2

from equation 2, y=102-x

Put the value of y=102-x in equation 1

0.10x+0.25(102-x)=17.10

0.10x+25.5-0.25x=17.10

-0.15x=17.10-25.5

-0.15x=-8.4

x=8.4/0.15

x=56

Put the value of x in y=102-x

y=102-56

y=46

Hence Andy has 56 number of dimes and 46 quarters.
