Answer:

Step-by-step explanation:

The y intercept is (0,2) so you can eliminate A and C because they have -2 and the slope is negative so you can eliminate B because it has a slope of +3 so you are left with D.

C.) 15,600

Since you are using letters as your password and you can't use each letter more than once, you have to do 26×25×24.

26 first because there are 26 letters in the alphabet, then 25 because you already used one letter and can't use it again, then 24 because you used two letters that can't be reused. Multiply those together and you should get 15,600.

Hope this helps!

Identify the graph of 3x^2+y^2=9 for T(-1,3) and write an equation of the translated or rotated graph in general form.

Archy [21]

ANSWER

D. Ellipse;

$3{x}^{2} +{y}^{2} + 6x - 6y + 3= 0$

EXPLANATION

The given equation is

$3 {x}^{2} + {y}^{2} = 9$

Dividing through by 9 gives

$\frac{ {x}^{2} }{ 3} + \frac{ {y}^{2} }{9} = 1$

This is the equation of an ellipse centered at the origin.

If this ellipse has been translated, so that its center is now at (-1,3), then the equation of the translated ellipse becomes

$\frac{ {(x + 1) }^{2} }{ 3} + \frac{ {(y - 3)}^{2} }{9} = 1$

We multiply through by 9 to get,

$3 {(x + 1)}^{2} + {(y - 3)}^{2} = 9$

Expand to obtain;

$3( {x}^{2} + 2x + 1) + {y}^{2} - 6y + 9 = 9$

Expand to obtain;

$3{x}^{2} + 6x + 3+ {y}^{2} - 6y + 9 = 9$

Regroup and equate to zero to obtain;

$3{x}^{2} +{y}^{2} + 6x - 6y + 3= 0$

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/25 for red, 1/20 fo

VARVARA [1.3K]

Probability helps us to know the chances of an event occurring. The probability of pulling a green or red card is 9 / 100.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

P = $\dfrac{Desired \ outcomes}{Posiible \ outcomes}$

The probabilities of different color cards being pulled are 1/25 for red, 1/20 for green, 1/15 for purple, and 1/10 for black Therefore, the probability of pulling a green or red card is,

Probability = 1/20 + 1/25

= (5 + 4) /100

= 9 / 100

Hence, the probability of pulling a green or red card is 9 / 100.
