We have that
Y²<span>-4x+4y-4=0
</span>you can rewrite the equation as 
4x=y²+4y-4
x=(y²/4)+y-1
x=0.25*(y²+4y)-1
x=0.25*(y²+4y+4-4)-1
x=0.25*(y²+4y+4)-5
x=0.25*(y+2)²-5

the equation of the parabola is of the form
x=a(y-k)²+h
is a horizontal parabola
where
(h,k)-----> is the vertex-----> (-5,-2)
a=0.25
a> 0--------> open to the right

the answer is
the option <span>D. Right

The answer is D, right because you rewrite the equation to a x= equation. Just by doing that, you know the equation has to be left or right. When rewriting the equation, the slope is positive, therefore it is facing right

Determine whether the relation is a function. {(−3,−6),(−2,−4),(−1,−2),(0,0),(1,2),(2,4),(3,6)}
Gennadij [26K]

Answer:

The relation is a function.

Step-by-step explanation:

In order for the relation to be a function, every input must only have one output. Basically, you can't have 2 outputs for 1 input but you can have 2 inputs for 1 output. Looking at all of the points in the relation, we see that no input has multiple outputs, so the answer is yes, the relation is a function.

The perimeter of a triangle is 42 yards. The first side is 5 yards less than the second side, and the third side is 2 yards less
Maru [420]
Let the second side be equal to x Then the first side is x-5 The third side will be x-5-2 = x-7 Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42 3x=44 X= 44/3 Therefore the second sides length is 44/3 The first sides length is 44/3 -5 = 29/3 The third side is 44/3 -7 = 23/3

Solve the equation for x and round your answer to the nearest hundredth.<br> 5x + 14 = 26
maks197457 [2]
5x + 14 = 26

subtract 14 on both sides

5x = 26 - 14

5x = 12

Divide 5 on both sides

x = 12/5

x = 2.4

That's only to the nearest tenth. To make it to the hundreth, just add another 0 at the end. It doesn't change the value of it.

x = 2.40 is your final answer.
