Answer:

In order down the left side, ...

y = 1/3x +2
y = 1/2x +3
y = 2x +6
y = -2x +3

Step-by-step explanation:

To put a linear equation in slope-intercept form, you solve for y, then simplify.

x -3y = -6

Subtract x and divide by -3:

y = 1/3x +2

2y -6 = x

Add 6 and divide by 2:

y = 1/2x +3

-x +(1/2)y = 3

Add x and multiply by 2:

y = 2x +6

2x +y = 3

Subtract 2x:

y = -2x +3

Comment on the algebra

Note that when we say add, subtract, multiply, or divide by something or other, we mean to do that to both sides of the equation. That is required by the properties of equality.

If you remember the rule: do the same thing to both sides of the equation, then algebra suddenly becomes much easier.

Answer:

x = -2

TU = 4

UB = 2

Step-by-step explanation:

you can add x^2 with 4x+10 and equate it to 6:

x^2 + 4x + 10 = 6

x^2 + 4x + 4

then u can use the roots formula : x = (-b ± √ (b2 - 4ac) )/2a

so it'll be x = {-4±[√16 - 4(4)]}/2

x= -2

then u can substitute it and find TU and UB

TU= (-2)^2 = 4

UB= 4(-2)+10 = 2

Let x represents the amount of a transaction and let f(x) represents the amount Isabel is charged for the transaction write a fu

Svetradugi [14.3K]

Answer:

$f(x) = \frac{Px}{100}$

Step-by-step explanation:

Let P% of the transaction amount is charged in the account.

So, if the transaction amount is x, then the charge for that transaction will be

$\frac{ Px }{ 100 }$ .

Therefore, if f(x) represents the amount Isabel is charged for the transaction then we can write $f(x) = \frac{ Px }{ 100 }$ , where P% is the rate of charge. ( Answer )

Please help quickly n show how you got answer

2) x=5 it is this because first u distribute the -2 to both the x and the +1 which gets you -2x-2=-12 then you add 2 (you add because you have to do the opposite of subtracting when you need to isolate the variable) to both sides to isolate 2x so you are left with 2x=10 then to get x all by itself you divide 2 to both sides so you are left with x=5

3) x=6 it is this because first you have to add 8 to both sides because you are doing the opposite to subtracting to get 7x alone so you get 7x=18+4x then you subtract 4x from both sides and get 3x=18 then divide 3 to both sides and you get x=6

4) a=2 it is this because first you distribute 3 into 6a and +12 which gets you 18a+36 , so you new equation will be 18a+36+4a=80 then you combine like terms so you combine 18a and 4a and you add them together to get 22a so your new equation is now 22a+36=80 then you subtract 36 from both sides to isolate 22a you are now left with 22a=44 then you divide 22 to both sides which leaves you with a=2

SORRY THIS IS A LOT! I TRIED TO EXPLAIN THE BEST I CAN! HOPE THIS HELPS :) have a nice day !
