Slope : 1
Y-intercept : 0
Use the equation y=mx+b
Put the slope in for m, and the y-intercept in for b
This would make the equation :
y=1x+0

I found the slope by finding two points on the graph, yours are marked. You go up 2, and right 2 to get from one point to the next so it would be a fraction. 2/2. You can simplify this to 1/1, which is the same thing as 1.

A.) which of these expressions is equivalent to 4 x x

Law Incorporation [45]

Answer:

a) The correct option is C: 4x

b) The correct option is B: 2x

Step-by-step explanation:

a) Usually when we have a real number multiplying a variable, we do not need to write the multiplication symbol.

So instead of writing:

4×x

We can write:

And this will be equivalent.

Then in this case the correct option is C.

b) We know that if we have the multiplication of A by n, this will be equivalent to add A n times.

Then if we have the sum of A, for example, 4 times, we have:

A + A + A + A

And this can be written as 4*A

In this case, we have the expression x + x.

So we are adding x two times, then this can be written as: 2*x, or, as we said earlier, this also can be written as 2x.

Then the correct option is option B.

Which statement correctly compares the mean number of students for the data in the plots?

satela [25.4K]

Answer:

"There are about 2 more students in each class at Oak Middle School than at Poplar Middle School."

Step-by-step explanation:

We need to compute the mean for each.

Poplar Middle School:

Lets list the numbers

20,20,20,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,24

The average is sum of all divided by number of numbers, that will be:

435/20 = 21.75

Oak Middle School:

The numbers are:

20,21,21,22,22,23,23,23,23,24,24,24,25,25,26,26,27,27,28,29

The average is sum divided by number of numbers, that will be:

483/20 = 24.15

The difference in mean is:

24.15 - 21.75 = 2.4

We can say, that is about 2 more students in Oak Middle School, correct answer choice is "2nd answer choice" - "There are about 2 more students in each class at Oak Middle School than at Poplar Middle School."

Please help me with this I’ll make you as brainlist

Arlecino [84]

Answer:

x = $3\sqrt{13}$ = 10.8

Step-by-step explanation:

Both problems are done the same way. I will do the first one and you do the second one. OK?

Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,

$6^{2} + 9^{2} = x^{2}$

$x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}$ = 10.8

None of the answer choices are to the nearest tenth. So, I am confused about that.

In the second problem, the answer should be 11.2
