1. 42+14x
2. 3(2x + 9)

Answers

Answer:

1. 56x 35x

what you had to do was add 42 plus 14x which gives you 56x. then for number two you had to multiply the numbers inside of the parenthesis by the number outside of the parenthesis which will give you 35x.

I’m not sure but, I think the second one is 6x+27. I don’t think you can’t simplify the first one, if that’s what your asking. But, if your asking what x is, please tell me and I’ll do that instead.

2[tex]^{2}[/tex] + 5 + 50 ÷ 2(5)

Answers

Hey there!

2^2 + 5 + 50 ÷ 2(5)

2^2 = 2 • 2 = 4

4 + 5 + 50 ÷ 2(5)

4 + 5 = 9

9 + 50 ÷ 2(5)

50 ÷ 2 = 25

9 + 25(5)

25(5) = 125

9 + 125

= 134

Answer: 134 ☑️

1). the submarine is descending 100 feet per minute. this is because the line decreases 100 on the y axis when the x axis increases by 1.
2). the submarine is descending 50 feet per minute. this is because the line decreases 50 on the y axis when the x axis increases by 1.
3). y=15x this is because the slope increases by 15 on the y axis when 1 is increased on the x axis. the y intercept is 0. this means that every hour of piano lessons they get paid $15.

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.


*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)


Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7
