19. -x-2 = 2/3x + 3
5/3 x + 3 = -2
5/3x = -5
x = -3

20. none are correct, you can double check me by plugging in the x and y values in the coordanates into the first problem none of them worked out in the first equasion so no need to test the second

21. -3 is the answer, capable of being done by using desmos

What is the product of (3a + 2)(4a? - 2a + 9)?
yan [13]

Answer:

The answer is 12a^3+2a²+23a+18 ....

Step-by-step explanation:

The given terms are:

(3a + 2)(4a² - 2a + 9)

Now multiply each value of second bracket with the first bracket:

=4a²(3a+2) -2a(3a+2)+9(3a+2)

=12a^3+8a²-6a²-4a+27a+18

Solve the like terms:

=12a^3+2a²+23a+18

Therefore the answer is 12a^3+2a²+23a+18 ....

What is the equation of this graphed line?
Eva8 [605]

Answer:

  • y = -9/8x + 7

Step-by-step explanation:

<u>Slope-intercept form is:</u>

  • y = mx + b

<u>Points given:</u>

  • (0, 7) and (8, -2)

<u>y-intercept is </u>

  • b = 7 as per the first point

<u>And the slope is:</u>

  • m = (-2 - 7)/(8 - 0) = -9/8

<u>So the line is:</u>

  • y = -9/8x + 7

I need help ASAP! Can anyone please check my work?
STALIN [3.7K]

A = event the person got the class they wanted

B = event the person is on the honor roll

P(A) = (number who got the class they wanted)/(number total)

P(A) = 379/500

P(A) = 0.758

There's a 75.8% chance someone will get the class they want

Let's see if being on the honor roll changes the probability we just found

So we want to compute P(A | B). If it is equal to P(A), then being on the honor roll does not change P(A).

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

A and B = someone got the class they want and they're on the honor roll

P(A and B) = 64/500

P(A and B) = 0.128

P(B) = 144/500

P(B) = 0.288

P(A | B) = P(A and B)/P(B)

P(A | B) = 0.128/0.288

P(A | B) = 0.44 approximately

This is what you have shown in your steps. This means if we know the person is on the honor roll, then they have a 44% chance of getting the class they want.

Those on the honor roll are at a disadvantage to getting their requested class. Perhaps the thinking is that the honor roll students can handle harder or less popular teachers.

Regardless of motivations, being on the honor roll changes the probability of getting the class you want. So Alex is correct in thinking the honor roll students have a disadvantage. Everything would be fair if P(A | B) = P(A) showing that events A and B are independent. That is not the case here so the events are linked somehow.

2×+2=6<br><img src="https://tex.z-dn.net/?f=5%20x%20%2B%204%20%3D%208" id="TexFormula1" title="5 x + 4 = 8" alt="5 x + 4 = 8" al
amm1812

Answer:

Step-by-step explanation:

hello

2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4  \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by  \ \ 2\\

so the solution is 2

5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4  \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by  \ \ 5

so the solution is 4/5

hope this helps
