Half the sum of 12 and x2 decreased by one-third x

Mathematics
1 answer:
MAXImum [283]3 years ago
5 0

The sum of 12 and x squared is

12+x^2

Half that sum is

\dfrac{1}{2}(12+x^2)

If we decrease this quantity by 1/3 x we have

\dfrac{1}{2}(12+x^2) - \dfrac{1}{3}x

Answer:

<u>Graph of the equation y = 2/5x - 1</u>

Please check the attached graph of the equation where:

The point  (0, -1) represents the y-intercept, it is the point where the line crosses the y-axis.

The point  (2.5, 0) represents the x-intercept, it is the point where the line crosses the x-axis.

Step-by-step explanation:

Given the equation

y = 2/5x - 1

<u>Determining the y-intercept:</u>

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

As the equation is given such as

y = 2/5x - 1

substitute x = 0

y = 2/5(0) - 1

y = 0 - 1

y = -1

so the ordered pair (0, -1) represents the y-intercept.

Thus, the y-intercept is: -1

<u>Determining the x-intercept:</u>

We know that the value of the x-intercept can be determined by setting x = y and determining the corresponding value of x.

As the equation is given such as

y = 2/5x - 1

substitute y = 0

0 = 2/5x - 1

2/5x = 1

x = 5/2

x = 2.5

so the ordered pair (2.5, 0) represents the x-intercept.

<u>Graph of the equation y = 2/5x - 1</u>

Please check the attached graph of the equation where:

The point  (0, -1) represents the y-intercept, it is the point where the line crosses the y-axis.

The point  (2.5, 0) represents the x-intercept, it is the point where the line crosses the x-axis.

Answer:

The three consecutive odd integers are: -1, 1, 3

Step-by-step explanation:

The three consecutive odd integers be x, x + 2, x + 4

Now according to the question

It is mentioned that

The four times the middle integer is two lower than tfhe sum of the first and third

i.e.

4(x+2) = [x + (x+4)] + 2

4x + 8 = 2x + 6

2x = -2

x = -1

Hence, The three consecutive odd integers are: -1, 1, 3
