\huge\text{Hey there!}


\mathsf{3ab - 2bc}

\mathsf{= 3(-4)(6) - 2(6)(-9)}

\mathsf{= -12(6) -12(-9)}

\mathsf{= -72 - (-108)}

\mathsf{= -72 + 108}

\mathsf{= 36}


\huge\textbf{Therefore, your answer should be:}}

\huge\boxed{\mathsf{36}}\huge\checkmark

An equation is shown below: 1 over 2 multiplied by x plus 3 over 2 equals 2 to the power of x What is the solution to the equati
Alborosie

Answer:

First option is correct. The solution of the equation is x=1.

Step-by-step explanation:

The given equation is

\frac{1}{2}x+\frac{3}{2}=2^x

The value of x, which satisfy the above equation is the solution of the given equation.

Put x=1 in the given equation.

\frac{1}{2}(1)+\frac{3}{2}=2^{1}

\frac{1+3}{2}=2

\frac{4}{2}=2

2=2

Since left hand side is equal to right side, therefore first option is correct.

Put x=2 in the given equation.

\frac{1}{2}(2)+\frac{3}{2}=2^{2}

\frac{2+3}{2}=4

\frac{5}{2}=4

Since left hand side is not equal to right side, therefore second option is correct.

Put x=4 in the given equation.

\frac{1}{2}(4)+\frac{3}{2}=2^{4}

\frac{4+3}{2}=16

\frac{7}{2}=16

Since left hand side is not equal to right side, therefore third option is correct.

Put x=8 in the given equation.

\frac{1}{2}(8)+\frac{3}{2}=2^{8}

\frac{8+3}{2}=256

\frac{11}{2}=256

Since left hand side is not equal to right side, therefore fourth option is correct.

Suppose the body length L in inches of a baby snake is given by L(m) = 1.5 + 2m, where m is the age of the snake in months until
Inessa [10]
L(m) = 1.5 + 2m.....when snake is 8 months..m = 8
L(8) = 1.5 + 2(8)
L(8) = 1.5 + 16
L(8) = 17.5 inches <==

L(m) = 1.5 + 2m....length is 25.5.....L(m) = 25.5
25.5 = 1.5 + 2m
25.5 - 1.5 = 2m
24 = 2m
24/2 = m
12 = m ....12 months <==

What parent function has the following applications: profit, gravity, and calculating area?
Ronch [10]

Answer:

Suppose that you have a square of side length x, the area of this square will be:

A = x^2.

Now, by dynamics, we know that the position of an object that is falling down from a height H, can be written as:

H(t) = (-g/2)*t^2 + H.

We can see a pattern, x^2 is used in both.

Now, profit can be also modeled with quadratic equations, where our objective is to find the maximum of the quadratic (so we can have the maximum profit)

Then the parent function that is useful for gravity, calculating area and profit is the quadratic function:

f(x) = x^2
