Y=4x+12
y=-2(x+2)2+2=>y=-4x-4+2=-4x-2=>
y=-4x+2
Use the elimination property:
2y=14
y=7
Put y value back to the first equation: 7=4x+12, solve for x and -5=4xso x=-5/4
(-5/4,7)

Which equation represents the hyperbola shown in the graph? A. x-3^2/64-y-1^2/36=1 B. x+3^2/64-y+1^2/36=1 C. y+1^2/64 - x+3^2/36
Leokris [45]

Answer:

C. (y + 3)²/64 - (x + 1)²/36 = 1

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo

My answer:

From the photo, the given information is:

  • The vertex : (−1, 5).
  • The center is (−1, −3).

As we know, the hyperbola has general equation for it is:

\frac{(y-k)^{2} }{a^{2}}-\frac{(x-h)^{2} }{b^{2}}=1

where h and k are the coordinate for the center (h, k) and we  only needed the center of the hyperbola to find our answer.

In this situation, we have:

\frac{(y-(-3))^{2} }{a^{2}}-\frac{(x-(-1))^{2} }{b^{2}}=1\\\frac{(y+3)^{2} }{a^{2}}-\frac{(x+1)^{2} }{b^{2}}=1

Hence, we choose C.

Hope it will find you well.

Estimate 4704 - 1193 by first rounding each number to the nearest hundred.
sveticcg [70]

Answer:

3500

Step-by-step explanation:

Given the following question:

4704-1193

To estimate we to the nearest hundred we have to look at the number next to the hundreds place value to determine if it's greater than five.

4704

0 < 5 = 4700

1193

9 > 5 = 1200

4700 - 1200

4700 -1200=3500

=3500

Hope this helps.
