The vertex form equation is y = a(x-h)^2+k
Lets substitute our given information.

y = a(x-1)^2+5

Now, lets put in the coordinate it needs to pass through.

8 = a(2-1)^2 + 5
8 = a + 5
a = 3

Now, lets make the equation now that we know a.

y = 3(x-1)^2+5

Hope this helps!

which expression represents purely real numbers and which expression represents non-real complex number?​
Ray Of Light [21]

Incomplete question. However, I provided some explanation about non-real complex numbers.

<u>Explanation</u>:

In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.

For example, the numbers 3i, 3 + 5i, 3i/4 are <u>non-real numbers</u> because of the addition of an imaginary part which is denoted by 'i'.

While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.

If 1/3 of a gallon of paint covers 1/9 of a gate, then how many gallons of paint are needed to cover the entire gate?
xxMikexx [17]

Answer:

3 gallons of paint

Step-by-step explanation:

If 3/4 of a gallon covers 2/5 of a wall, this means that a half of 3/4 gallons can cover 1/5 of a wall.

By knowing this, you can just make up your own expression

(the trick is to find a way to break it down to one, so you can multiply and manipulate it to save yourself some brain cells)

1/5+1/5+1/5+1/5+1/5= whole wall if  3/4/2=3/8  = amount of paint to cover 1/5 wall, then  (3/8)⋅5=3/8+3/8+3/8+3/8+3/8=15/8≈1.875

since we're talking about real life it would be 2 gallons of paint instead of 1.875 gallons to paint the whole wall
