Impossible question for me plz help

klio [65]

Answer:

The line x = 3 is simply a vertical line that passes through every single point where x is equal to 3.

One that is is parallel and passes through (-4, 7) will be in the same format, just with another number. The given point has an x-coordinate of -4, so the line is:

x = -4

Describe the solution(s) to 9x² - 36x + 36 = 0 by just determining the radicand. Show your work. (10 points) Part B: Describe th

Mariana [72]

The solution to the equations are:

9x² - 36x + 36 = 0 has two equal real solutions
x² - x + 4 = 0 has no real solutions
The factored expression of 4x² + 23 – 35 is 4(x² -3)

<h3>Part A: Describe the solution</h3>

The equation is given as:

$9x\² - 36x + 36 = 0$

The above equation is a quadratic equation which can be represented as:

$ax\² + bx + c = 0$

The discriminant (d) is calculated as:

$d = b\² - 4ac$

So, we have:

$d = (-36)\² - 4 * 9 * 36$

$d = 0$

A discriminant of 0 means that the equation has two equal real solutions

Hence, 9x² - 36x + 36 = 0 has two equal real solutions

<h3>Part B: Describe the solution</h3>

The equation is given as:

$x\² - x + 4 = 0$

The above equation can be represented as:

$ax\² + bx + c = 0$

The discriminant (d) is calculated as:

$d = b\² - 4ac$

So, we have:

$d = (-1)\² - 4 * 1 * 4$

$d = -15$

A discriminant of -15 means that the equation has no real solutions

Hence, x² - x + 4 = 0 has no real solutions

<h3>Part C: The solution to the expression</h3>

We have:

$4x\² + 23 - 35$

Evaluate the difference

$4x\² -12$

Factor out 4

$4(x\² -3)$

Hence, the factored expression of 4x² + 23 – 35 is 4(x² -3)

Simplify completely

Mandarinka [93]

Answer: x+2 / x+ 9, x = -2, x=-9 ( A )

Solution:

Breakdown the problem into two sets

Step 1: simplify x^2 -10x - 24

Factorize the above equation,

Multiply the last term (24) with the first term coefficient i.e. 1

Step 2: Then, find the factors of 24 in a way that when you add or subtract it sums up to 10

x2 - 12x + 2x - 24 >>>> (x2-12x) + (2x-24) >>> take common

>>>> x(x-12) + 2( x-12)

Step 3: (x + 2) (x - 12)

Step 4: Step 1: simplify x^2 - 3x - 108 using the same steps

x2 - 12x + 9x - 108 >>>> take common x(x-12) + 9 ( x -12) >>>

(x + 9) (x - 12) final product

Now, Simplify the equation as a whole

(x + 2) (x - 12) / (x + 9) (x - 12) Note: (x - 12) cancels out

= (x + 2) / (x + 9) with x= -2 and x= -9

A scientist used a microscope to count the number of bacterial cells in a petri dish every hour. The graph shows the data collec

Alex777 [14]

The required relationship shown by the graph is the exponential relationship $n =2^t$ . Option a is correct,

Given that,

A graph has been shown, showing the data, what is the relationship between the number of bacteria with time is to be determined.

<h3>What is a graph?</h3>

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Since the recorded value from the graph is
At, t = 1 ; n = 2
At t = 2 ; n = 4
At t = 3 ; n = 8
At t = 4 ; n = 16
At t = 5 : n = 32
Here the above data show the exponential relation between n and t with the base value 2 i.e. $n =2^t$

Thus, the required relationship shown by the graph is the exponential relationship of $n =2^t$ . Option a is correct,
