Answer:

f(x) = 12*(2)^x

Step-by-step explanation:

A generic exponential equation is written as:

f(x) = A*(r)^x

And we also know that this equation passes through:

(-1, 6)

(0, 12)

(1, 24)

(2, 48)

For the second point, (0, 12) we know that when f(0) = 12

Then:

f(0) = 12 = A*(r)^0

And for every real number different than zero, a^0 = 1

Then:

f(0)  = A*1 = A = 12

Then the equation is:

f(x) = 12*(r)^x

Now we can use one of the other points, like (1, 24)

Then f(1) = 24

We can solve:

f(1) = 24 = 12*(r)^1  = 12*r

24/12 = r

2 = r

Then the equation is f(x) = 12*(2)^x

Now we need to check if this function also passes through the points (-1, 6) and (2, 24):

f(-1) = 12*(2)^-1 = 12/2 = 6

f(2) = 12*(2)^2 = 12*4 = 48

Nice.

So we can see that the function is f(x) = 12*(2)^x

Answer:

$33.92 ($1.92 in tax)

Step-by-step explanation:

% values are 1/100ths. 32.00/100=0.32. 0.32(6) = 1.92.

 $32.00

+   $1.92

=$33.92 total.

Answer:

6x+2

Step-by-step explanation:

The perimeter is all of the sides added together.

We know that in a rectangle, sides that are parallel to each other are the same.

So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.

(2*(2x+1))+(2*(x))

(4x+2)+(2x)

4x+2+2x

6x+2

Answer:

Step-by-step explanation:

You have to realize that the absolute value function will change the sign of its argument only if that argument is negative.

108. |x -7| = x -7 . . . . . true for x-7≥0

  x ≥ 7 . . . . makes the statement true

__

1a. When m < 9, the value 6m is less than 54, so 6m-54 < 0. That means the absolute value function changes the sign of its argument:

  54 -6m . . . . . simplified form for m < 9

__

1b. |y -x| = y -x . . . when y > x, the argument of the absolute value is positive

An expression is defined as a set of numbers, variables, and mathematical operations. The value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the statement that the sum of a number x and 7 is 35. Therefore, the given statement "the sum of a number x and 7 is 35" in the form of an expression can be written as,

x + 7 = 35

Subtract 7 from both the sides of the equation,

x +7 - 7 = 35 - 7

x = 28

Hence, the value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.

how was ur day

Answer:

m<A = 30degrees

m<B = 70degrees

Step-by-step explanation:

Find the diagram attached

From the diagram;

m<A + 150 = 180

m<A = 180 - 150

m<A = 30degrees

Also since the sum of angles in a triangle is 180degrees, hence;

m<B+m<A + 80 = 180

m<B+30+80 = 180

m<B+110 = 180

m<B = 180 - 110

m<B = 70degrees

Answer:

We bought 10 Pounds of Chocolate, and 5 Pounds of Candy.

Step-by-step explanation:

Hey!

==================================================================

Let's make a chart!

                 Lbs     Price  Cost

Chocolate | x      | 2.50 | 2.50x

Candy       | 15-x | 3.00  | 3.00(15-x)

Equation:

2.50x + 3.00(15-x) = 40

--------------------------------------------------------------------------------------------------------------

⇒ 2.50x + 3.00(15-x) = 40

-Distribute 3 over 15-x

⇒ 2.50x + 45 - 3x =40

-Combine Like Terms

⇒ -0.5x + 45 = 40

-Subtract 45 from both sides.

⇒ -0.5x + 45 = 40

            -45   -45

--------------------------

⇒ -0.5x = -5

-Divide by -0.5 on both sides

⇒ -0.5x/-0.5 = -5/-0.5

⇒ x = 10

That means we bought 10 Pounds of Chocolate.

---------------------------------------------------------------------------------------------------------------Since Candy was 15-x, we can Substitute 10 as x, and Solve:

⇒ 15 - 10

⇒ 5

That means we bought 5 Pounds of Candy.

--------------------------------------------------------------------------------------------------------------

We bought 10 Pounds of Chocolate, and 5 Pounds of Candy.
