Answer:

In order: y = 29, 8, -1, 2, 17

Step-by-step explanation:

Simply plug in what x equals to get the coordinating y!

When x = -2       6(-2)² - 3(-2) - 1 = 29

When x = -1        6(-1)² - 3(-1) - 1 = 8

When x = 0        6(0)² - 3(0) - 1 = -1

When x = 1         6(1)² - 3(1) - 1 = 2

When x = 2        6(2)² - 3(2) - 1 = 17

A video game randomly chooses your car color and type. The probability of getting a red car is 0.20, and the probability of gett
pishuonlain [190]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Event A: You get a red car

and

P(A)=0.20

Similarly,

Event B: You get a convertible

and

P(B)=0.40

So, if A and B are independent , then they must satisfy,

P(A).P(B)=P(A\cap B)

So,

P(A\cap B)=0.4\times 0.2=0.08

Hence, Option 'D' is correct, which states that the probability of getting a red convertible is 0.08.

Bruce is solving a system of equations.
Valentin [98]

Answer:

Option 3,4,5 are correct.

Step-by-step explanation:

The system of equations are:

3x+5y=9\,\,\,\,(1)\\x-y=-5\,\,\,\,(2)

Multiply equation (2) with -3 and add with equation (1)

3x+5y=9\\-3x+3y=15\\-------\\8y=24\\y= 24/8\\y=3

Value of y is 3

Putting value of y in eq(2)

x-y=-5\\x-3=-5\\x=-5+3\\x=-2

Value of x is -2

So, Option 3,4,5 are correct.
