Valerie is ordering salads and drinks for her friends. salads cost $7 each, drinks cost $3 each, and there is a $5 delivery char
Helen [10]

Since there is a $5 delivery charge, Valerie will surely spend those money.

Also, since a salad costs $7, and Valerie buys 3 of them, she will spend 21 more dollars.

So, salads and delivery charge sum up to 21+5 = 26

This means that Valerie has 50-26 = 24 dollars left. A drink costs $3, so she can buy

\dfrac{24}{3} = 7 drinks.

The ellipse with center C(2, -3), vertices V(-8,-3) and V2(12,-3), and foci F1(-4,-3) and F2(8,-3). 6.
attashe74 [19]

Answer:

(x-2)²/100 + (y+3)²/64 = 1

Step-by-step explanation:

C (2,-3): h=2 k=-3

semimajor axis (CV): a=12-2=10

center-foci: c=8-2=6

semi minor axis: b² = a²-c²= 100 - 36 = 64

equation: (x-h)²/a² + (y-k)²/b² = 1

(x-2)²/100 + (y+3)²/64 = 1
