Answer:

(4,-3)

Step-by-step explanation:

Multiplying the bottom equation by -6, we get -6x+12y=-60.

Adding this to the first equation gives 15y=-45, and thus y=-3.

So, it follows that 6x+3(-3)=15, and thus x=4.

PLEASE HELP!!! WILL GIVE LOTS OF POINTS IF ANSWERED!!!

AlexFokin [52]

Slope intercept form: y=3/4 - 3

slope:3/4

Y-intercept: -3

Because you subtract 4y from both sides to get it on the other side of the equation. You don’t want it to be 4y=3x-12 though so you would divide both sides by 4 which would give you y=3/4x-3. I hope this is right and it helps

A card is drawn one at a time from a

soldi70 [24.7K]

Answer:

$\dfrac{2}{11}$

Step-by-step explanation:

It is given that a card is drawn one at a time from a well-shuffled deck of 52 cards.

Total repetitions of this experiment = 11

Number of kings in the experiment = 2

Let E is the event in which a king is drawn in the 11 trials. So

$P(E)=\dfrac{\text{Number of kings in the experiment}}{\text{Total repetitions of this experiment}}$

$P(E)=\dfrac{2}{11}$

Therefore, the experimental probability P(E) is $\dfrac{2}{11}$ .

If the discriminant of a quadratic equation is 10, how many solutions does the equation have?

Sunny_sXe [5.5K]

Answer:

C. 2

Step-by-step explanation:

If the discriminant is >0 we have 2 real solutions

If the discriminant is =0 we have 1 real solutions

If the discriminant is <0 we have 2 complex solutions (no real solutions)

since 10>0 we have 2 real solutions

The point (2,6) lies on the graph of the equation y = kx^2 - 3x Find the value of K

MAVERICK [17]

Answer:

Step-by-step explanation:

y = kx² - 3x

Since the points lie on the graph we can substitute the values of x and y that's

( 2 ,6) into the equation to find k.

We have

6 = (2)²k - 3(2)

6 = 4k - 6

4k = 6 + 6

4k = 12

Divide both sides by k

That's

$\frac{4k}{4} = \frac{12}{4}$

We have the final answer as

Hope this helps you
