Solve for x:
3/4(3x+4)=4(x+6)

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

3/4 (3x + 4) = 4 (x + 6)

9x/4 + 3 = 4x + 24

9x/4 - 4x = 24 - 3

9x/4 - 4x = 21

multiply by 4 on both sides

9x - 16x = 84

-7x = 84

x = 84 / -7

x = -12

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Explain your steps.Can you help me and explain this question... Thanks!

Answers

So there are 12 months in a year and he delivers 8,520 in that time. You must divide 8,520 by 12 which gives you how many he delivers in one month. 8,520/12=710. You are looking for two months so you should then multiply 710 by two giving you how much he delivers in 2 months.
710*2=1,420
Max delivers 1,420 pieces of mail in two months

What is the fuction eqation for (0,-2)and (5,-1)

Answers

y = mx + b

m is the slope
b is the y-intercept

First find the slope

slope = (y_2-y_1)/(x_2-x_1) = (-1+2)/(5-0)= (1)/(5)

So far we have: y = 1/5x + b

Now we need to find b

y = 1/5x + b

Plug in (0,-2)

-2 = 1/5(0) + b

-2 = b

So the final equation is \boxed{y=(1)/(5)x-2}
f(x) = 1/5 x - 2

-2 is your y intercept and using (y-y)/(x-x) you can get slope 

 (-1 - - 2)/ (5-0) = (-1+2) / (5) = 1/5
