4v^2+12v+9=0

on this point we can use the formula to factor

v=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

where a is 4, b is 12 and c is 9

replacing

v=\frac{-(12)\pm\sqrt[]{(12)^2-4(4)(9)}}{2(4)}

and solving

\begin{gathered} v=\frac{-12\pm\sqrt[]{144-144}}{8} \\  \\ v=\frac{-12\pm\sqrt[]{0}}{8} \\  \\ v=-\frac{12}{8}=-\frac{3}{2} \end{gathered}

The root is

-\frac{3}{2}

then the polynomial has one root -3/2 if we rewrite the polynomial is

(v+\frac{3}{2})^2=0

or

(2v+3)^2=0

Find the slope Y=5x+12
NikAS [45]

Answer: The slope = 5.

Step-by-step explanation:

The equation of a line in the slope -intercept form is given by :-

y=mx+c

,where  m= slope , c= y-intercept.

The slope of a line represents the rate of change of y with respect to x.

Given: Equation of line : Y= 5x+12

Here Slope (m)=5

Hence, the slope = 5.

Describe the end behavior of the function:<br> f(x) = 1/2*2^x +3
suter [353]
Although there is (1/2) in the front of the expression, the base is 2, not (1/2). (1/2) is a positive number, and 2 is a positive number larger than 1, so as x approaches infinity, f(x) approaches infinity as well. as x approaches negative infinity, f(x) approaches 3.

I’ll fail if I don’t get this right pls help
son4ous [18]

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

3(x - 2) + 7x =  \frac{1}{2} (6x - 2)

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

3x  - 6 + 7x = 3x - 1

Now, we would shift all x terms to the left and all number terms to the right.

3x + 7x - 3x =  - 1 + 6

After simplifying, the final equation would be:

7x = 5

This is a linear equation and it has one solution.

x =  \frac{5}{7}

Which sequence isn’t a geometric progression?
AVprozaik [17]

Answer: 3, 6, 9, 12

Step-by-step explanation:

A geometric progression has a common ratio.

2,6, 18 and 54 has a common ratio of 3. When you multiply the first number by 3, you get the second number and the same thing applies to the third number.

1, 5, 25 and 125 has a common ratio of 5. When you multiply the first number by 5, you get the second number and the same thing applies to the third number.

4, 8, 16 and 32 has a common ratio of 2. When you multiply the first number by 2, you get the second number and the same thing applies to the third number.

3, 6, 9 and 12 is an arithmetic progression as 3 is added to each number

34kurt

Answer:

  |h-13| ≤ 2

Step-by-step explanation:

The difference between the height of the plant (h) and show size (13 in) can be written as ...

  h - 13

This value is allowed to be positive or negative, but its absolute value must not exceed 2 inches. Thus, the desired inequality is ...

  |h -13| ≤ 2
