Answer:

2, 4

Step-by-step explanation:

Ok so for this you have to substitute. y=4 so you put a 4 where the y is. This becomes

4 - 3x = -2 We can already rule out (2,2) and (4,2) Why? Because the y is not a 4. So it’s gonna be either (0,4) or (2,4). Now, we have to find x. We have to isolate it. You do this by subtracting 4 from both sides.

4 - 4 - 3x = -2 - 4 Now Simplify

-3x = -6 Why -6? Because you can’t subtract a positive from a negative so it becomes -2 + -4. Since they are both negatives, you just add them together, then put the negative sign.

Now divide -3 from both sides. Which becomes

x = 2

If the price of a purse increased from $45 to $54, what was the percent of increase
Marrrta [24]
If you set it up in cross multiplication then you would have (x/100 = 45/54) then cross multiply so then i would look like this (54x/4,500) so from there you would divide 54 from 4,500 i hope this helps in any way  oh and it should come up to be 83.3333333 which would be 83% lol

What is the equation of this graph
Soloha48 [4]

Answer:

Step-by-step explanation:

hello :

an equation of this graph is : f(x) = a(x-h)²+k when (h,k) the vertex

so : h=5 and k= -4

f(x) = a(x-5)²-4....... now calculate : a

the y- intercept is :  - 6.5 means : f(0) = - 6.5

put x=0 and f(x) = - 6.5

you have : -6.5 = a(0-5)²-4

-6.5 = 25a - 4

25a = -2.5   so : a= -2.5/25= 1/10

the equation is :

<h2>f(x) = (1/10)(x-5)²-4</h2>
