ANSWER
The vertex is (-2,1)
EXPLANATION
We want to find the vertex of
We complete the square to obtain,
The first three terms forms a perfect square trinomial.
The vertex form is
This equation is in the form;
where (h,k)=(-2,1) is the vertex.
Gas in July is 2.3 times Gas in June
That means Gas in July (252.57) equals 2.3 times gas in June, or “n”
242.57= 2.3 x n and solve for n
Divide both sides by2.3
Calculator gives 105.465
Rounded to nearest HUNDRED is 100
Rounded to nearest HUNDREDTH would be 105.47
Check the answer to see if July gas is 2.3 times June gas
June gas 105.47 x 2.3 is 242.57
So the answer is 105.47 Rounded to nearest hundredth
Answer:
Step-by-step explanation:
2x + 3y = 2
x = 2 - 3y /2
x + y = 0
substitute the value of x
+ y = 0
2 - 3y + 2y = 0
2 = y
again,substitute the value of y
x = 2 - 3y / 2
=2 - 3*2 / 2
=2 - 6 / 2
=-2
(A)
Choice (B) is not the right answer because I
it's only 3rd order. But because f(x) goes to negative infinity when x goes to positive infinity means that the right answer is (A).
