3a+2b=8<br><br> \displaystyle a = 6b + 6 a=6b+6

kherson [118]

First, let's write it like this:
$3a+2b=8$
Subtract $2b$ from both sides.
$3a+2b-2b=8-2b$
$3a=8-2b$
Divide both sides by 3.
$\frac{3a}{3}=\frac{8-2b}{3}$
$a=\frac{8-2b}{3}$

Now that we know what's the value of $a$ , let's find the value of $b$
$3\cdot \frac{8-2b}{3}+2b=8$
Let's take the first part.
$3\cdot \frac{8-2b}{3}$
Multiply the fractions.
$=\frac{\left(8-2b\right)\cdot \:3}{3}$
Cancel the common factor, which is 3.
$=8-2b$
We would be left with.
$=8-2b+2b$
Add like terms.
$=8$
We would be left with.
$8=8$
Subtract 8 from both sides.
$8-8=8-8$
$0=0$

This tells us that $b$ can be any number.

Let me know if you need any help!

Find the slope of each line then tell what the slope represents

morpeh [17]

1. find slope
x=tickets sold
y=money made
slope=(y2-y1)/(x2-x1)
take any point
(5,23.75) and (10,47.50)
input (note, (x,y))
(47.50-23.75)/(10-5)=23.75/5=4.75
slope=4.75
y=mx+b
m=slope
b=yintercept
y=4.75x+b
input
47.5=4.75(10)+b
47.5=47.5+b
b=0

equation is y=4.75x
if ticket sold is 24 then x=24
y=4.75(24)
y=114
answer is $114

2. points
(0,56.00) and (3,45.5)
slope=(y2-y1)/(x2-x1)
slope=(45.5-56.00)/(3-0)=-3.5
y=-3.5x
slope=-3.5
logic it yourself
equation is
y=-3.5x+0
y intercept is when x=0 so when the start of it was or when time=0
x intercept is when y=0 is when he has no money left

1.a. rate of change=4.75
   b. $114

2. a.do this yourself, (desmos graphing calculator)
   b. slope=-3.5 (duh, means money goes down with time)
   c. equaiton is y=-3.5x+0, xint meanss when he has no money, y int means when time=0 or when it started

The price of an item has risen to $156 today. Yesterday it was $65 . Find the percentage increase.

faltersainse [42]

That's a BIG increase in price! What cost $65 yesterday is now $156. What was the increase? $156 - $65 = $91.

Next: $91 is what fraction of $65? Divide. Answer: 1.4.

Finally, multiply this last result by 100%: 140% (answer)
