Can somebody pls help me understand this question? (Give an explanation)

Question:
Below is a graph of 2 lines. Match the line with its slope.

Answers

Answer:

l: 1

k: 2

Step-by-step explanation:

The slope of a line is "the amount it goes up divided by the amount it goes right".

So if you pick a point on the line, and then step one grid position to the right, how much does it go up (or down, then you have a negative slope)?

In line l, it goes up one grid position for every step to the right, hence the slope is 1.

In line k, it goes up two positions for every step to the right, hence the slope there is 2.

Given is that at 6am one morning the temperature was -14 degrees by noon it rose 8 degrees and then rose another 2 degrees by 3pm. By 6pm the temperature had dropped 5 degrees

We can write -

T{6 AM} = - 14°

Answers

Answer:

C

Step-by-step explanation:

We can solve this by analyzing if the event causes the result. If it does not, then there is correlation but not necessarily causation

A. Event: Rainfall. Result: Water level rises

Does rainfall cause an increase in water level? Yes, so this is incorrect

B. Event: Temperature increase. Result: Ice melting

Does an increase in temperature cause ice to melt faster? Yes, so this is incorrect

C. Event: More people have vision loss. Result: Hearing aids sales increase

Does more people having vision loss cause hearing aids sales to increase? No, vision loss does not cause a need for hearing aids -- hearing loss would, but vision loss does not. This is correct

D. Event: A student makes fewer mistakes. Result: A better grade

Do fewer mistakes cause better grades? Yes, so this is incorrect

Answer:

1/9 (2m - 16) = 1/3 (2m + 4)

expand

2/9m- 16/9 =2/3m +4/3

move m to other side

- 16/9 =2/3m (-2/9m) +4/3

simplify

- 16/9 =(6-2)/9m +4/3

- 16/9 =4/9m +4/3

move 4/3 to other side

- 16/9 -4/3 =4/9m

- 16/9 -12/9 =4/9m

-28/9 = 4/9m

multiply by 9

4m= -28

The sum of 6 consecutive integers is 387. What is the sixth number in this sequence.

Answers

Answer:

67!

Step-by-step explanation:

A way to look at it is, since the number is 387, it can be broken into 6 parts. 50x6 is about 300. That leaves 87 to be left over. So it's safe to assume each number will be around 50-60, so I started to add up six consecutive numbers together until I reached my final set of numbers to reach 387.

My numbers were 62+63+64+65+66+67=387

4x-y=10 and y=2x-2 answers

Answers

4x - y = 10, y = 2x - 2

4x - (2x -2) = 10

4x - 2x + 2 = 10

2x = 8

x = 4

4(4) - y = 10

-y = -6

y = 6

So x = 4 y= 6

Hope this helps!
Brainliest and a like is much appreciated!

Answer:

y = 6

x = 4

How to find 'x':

4x - y = 10

y = 2x - 2

First, you need to substitute the 'y' into the first equation.

4x - 2x - 2 = 10

Next, add the x's together. As it's a negative 2x then take away 2 from 4.

2x - 2 = 10

3. Now that it's a normal equation, you can add 2 to cancel out the -2

2x = 8

4. Then divide the 8 by 2 and you will get the answer to x which is 4

x = 4

How to find 'y':

1. Now that we have found out 'x'. Let's go back to y = 2x -2 and use the x to found the answer out. It should be something like this:

y = 2x - 2

y = 2(4) - 2

y = 8 - 2

8 - 2 = 6

y = 6

Conclusion:

So the answer would be:

y = 6

x = 4

You can see if it's correct by putting y into 4x - y = 10.:

4x - 2 = 10

4(4) - 6 = 10

16 - 6 = 10

So that means that y and x are the correct answer.

Translate. Eight less than the difference of a number and five is twelve.

Answers

Answer:

(x - 5) - 8 = 12

Step-by-step explanation:

Lets portion each part out:

Eight less than

The difference of a number and five

Is twelve.

First, we must write down the portion with "a number" in it: x - 5. We use subtraction because the sentence states "the difference".

Next, we will write down "eight less than". The problem states that twelve is "eight less than" the difference. This means that we must subtract 8 from out first part: (x - 5) - 8

Finally, the sentence tells us that this equals twelve: (x - 5) - 8 = 12
