Which equation could generate the curve in the graph below

Mathematics

Setler79 [48]3 years ago

The curve has been attached and the answer choices are:

y = 3x² – 2x + 1

y = 3x² – 6x + 3

y = 3x²<span> – 7x + 1
</span>
The attached graph has a vertex in the first quadrant. Therefore, the coordinates of the vertex would be both positive.

Let's start with first equation:

                                               y = 3x² – 2x + 1

using the equation of axis:
                                            x = -b/2a
                                            x = 2/6
                                            x = 1/3
SUbstituting the value of x in the main equation to get the y-coordinate of the vertex.
                                               y = 3(1/3)² – 2(1/3) + 1
                                               y = 3/9 – 2/3 + 1
                                               y = 1/3 – 2/3 + 1
                                               y = (1 - 2 + 3)/3
                                               y = 2/3

Hence, the vertex would be:
                                             (h,k) = (1/3 , 2/3)

Also, the leading coefficient is positive, so the parabola would be concave up.

Thus the final answer choice will be:

                                             y = 3x² – 2x + 1

Answer:

$30 down  

and 10 installments of $10 each

Step-by-step explanation:

paying $30 down means the left price to divide into installments is : 130-30 = 100

since he will pay the rest in equal installments, we divide  by the number of installments to get how much each one will be :

100/10 = $10

What is equivalent to 3x-4y=6
Andreyy89

Answer:

y= (3/4) x - (3/2)

Step-by-step explanation:

3x - 4y = 6 (using algebra add the 4y to the other side & subtract the 6 to the other side >> 3x - 6 = 4y (then divide everything by 4 to get y by itself) >> 3/4x - 6/4 = y (then simplify) >> 3/4x - 3/2 = y

SO my cake usually cooks from the top but stays undercooked at the bottom. I used olive oil instead of butter, and I didn't add
Ludmilka [50]

Answer:

Step-by-step explanation:

If your cake looks done outside but remains uncooked/gooey in the center, it means that its not completely cooked. Always insert a skewer in the center of the cake towards the finishing time to see if it comes out clean. If it doesn't then cook for few minutes more, and check after 5-10 minutes.
