(PLZZZZ HELP ME its actually easy I am trying to check my work) Bob's family of three was driving to Washington D.C.. They were

going to stay overnight, sightsee during the next day, and return home in the evening. They had to pay for dinner, breakfast, and lunch. They were to sleep at grandmas house. Breakfast at MC Donald's was $4.89 each. Lunch at Kentucky Fried chicken was $5 each. Dinner at Wendy's was $8.49 each. Was $60 enough money to pay for their food? (My answer was not enough was that correct?)

A bag contains an unknown number of marbles. You know that P(red) = 1 and P(green) = 1. What can you conclude about how many mar
Nataly [62]

The number of marbles in the bag illustrates probability

The conclusion about the number of marbles in the bag is that the bag can only contain one type of marble

<h3>The number of marbles in the bag?</h3>

The probabilities are given as:

P(Red) = 1

P(Green) = 1

For a distribution, the sum of all probabilities must equal to 1.

This means that:

P(Red) + P(Green) = 1

So, we have:

1 + 1 = 1

This gives

2 = 1

The above equation is false because 2 does not equal to 1.

So, the conclusion about the number of marbles in the bag is that the bag can only contain one type of marble i.e. either red marbles are in the bag or blue marbles are in the bag

How to solve a system of equations using elimination?
Nastasia [14]
If  you have a problem like: 
4x+2y=20
2x+2y=16
 You would subtract
4x-2y=20
-2x+2y=16
You would get the new problum
2x=4
You now want to divide the 2 on both sides to solve for x
x=2

Now that you've solved for X you want to solve for y. So use substitution to solve for y. You would want to substatute the x for the 2 in either of the problums. I'll use the first one.
4(2)+2y=20

You first want to multiply te 4(2) you would get a new problum.
8+2y=20

Now you want to subtract the 8 on both sides.
2y=12

The last step to solve for y is to divide the 2 on both sides.
Y=6

So your answers would be
x=2
y=6

Find the slope of the line through the points (6,16) and (−6,4)
MakcuM [25]

m = \frac{y2-y1}{x2-x1}

m = \frac{4-16}{-6-6} \\m = \frac{-12}{-12} \\\\m = 1

Therefore, the slope of the line is 1. In case if you want to know the equation.

y=mx+b\\y=x+b\\4=-6+b\\4+6=b\\10=b\\

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

y=mx+b\\y=x+b\\16=6+b\\16-6=b\\10=b\\

It's the same, you can use any orders given.

Overall, the slope is 1 and the equation is y=x+10

Answer:

B

Step-by-step explanation:

given y = kx

To find k use the x and y values of the coordinate point given (- 5, 3)

k = \frac{y}{x} = \frac{3}{-5} = - \frac{3}{5}
