Javier Simplified The Expression Below. Find Anddescribe The Three Mistakes He Made.20x- (203) = (5x]*

Answers

Answer 1

Answer:

Step-by-step explanation:

Javier did not raise the coefficients to the third power

When Javier raised [tex]x[/tex] to the third power, he wrote that [tex](x^1)^3=x^4[/tex], but it equals [tex]x^3[/tex].

In the last step, Javier divided the exponents. He should have used the quotient of powers property and subtracted them.

Identify the graphed linear equation?

Answers

Answer:

C

Step-by-step explanation:

The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off.  And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should. If I'm wrong, pick D for sure.

Answer:

y=-5x-2

Step-by-step explanation:

Can someone explain Slope to me? I literally have no idea what is from my teacher or from Aleks. I don't get what y1 and y2 are and i don't get what rise or run is. I have no idea how to get slope (brainliest for whoever explains a function too)

Answers

Yeah, I know Alex sucks. SO slope is the change in Y over x. So to find slope for ex. is lets use points (8,4) and (6,5) the equation to find slope is Y2-Y1 over X2-X1 or Y2-Y1 / X2-X1 and that basically the y's on the points you have. In this case it will be 4 and 5 since y always comes second or after the x. What I like to do is this X1(8), Y1(4) and X2(6), Y2(5). After you have that set up you just put them in the equation it will be 5-4/6-8 which is -1/2 use calculator. So Y is the y-axis and X is the x-axis.

Function is when every input(x) has only one output(y) . For example if we have the table

X,1 , 4 , 5, 9, 10 this is not a function because the -3 has both 9 and 10 for an output.

Y,2, 6 ,6, -3 , -3

A function will look more like this

1 2 3 4 5 6

2 4 6 8 10 12 every output has only one input

I recommend to watch Brian McLogan on youtu he can really help. Just search anything then his name. Or even Function then his name he explains it really well.

In a family of 11, what is the probability that there will be more boys than girls

Answers

Answer:

P(all female)= 1/2 x 1/2 x 1/2 = 1/8

P(all male ) = 1/2 x 1/2 x 1/2 = 1/8

P(all one gender) = P(all female) + P(all male) = 1/8 + 1/8 = 1/4

What is the probability that a three-child family is two girls and one boy?

Each possible birth order has P=1/8. That is, P(G,G,B)=P(G,B,G)=P(B,G,G)=1/8.

So, P(2G,1B)= 3/8 and P(1G,2B)= 3/8.

This allows us to write the overall gender probability distribution for families of three children as follows:

1/8 will be three girls

3/8 will be two girls and one boy

3/8 will be one girl and two boys

1/8 will be three boys

Adding it all up, we have 1/8 + 3/8 + 3/8 + 1/8 = 1 (100%)

School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. How many chaperones must there be for 82 students? A. 6 chaperones B. 41 chaperones C. 7chaperones D 3 chaperones

Answers

Answer:

A. 6 chaperones

Step-by-step explanation:

Since it's 2 chaperones per 25 students you would need to see how many times 25 can fit into 82

82/25 = 3.28

You can round that number to 3

Then you'll multiply 3 by 2 to get your number of chaperones for the school trip

3 x 2 = 6

There's still students left but not enough for there to be another chaperone so the answer is 6

Let's solve your equation step-by-step.

7x−7=3x−23

Step 1: Subtract 3x from both sides.

7x−7−3x=3x−23−3x

4x−7=−23

Step 2: Add 7 to both sides.

4x−7+7=−23+7

4x=−16

Step 3: Divide both sides by 4.
