Slope is defined as the change in y divided by the change in x between two points. Slope = y2 - y1/x2 - x1 -2 - 4/ -1 - (-4) -6/3 -2 Hope this helps!

Which equation represents the function graphed on the coordinate plane?
Ulleksa [173]

Answer:

The two lines connect at (-4,-10)This means you would add 4 to x and then subtract 10 from the equation.

This means the answer is: B.g(x) = |x + 4| – 10.

Two cards are drawn with replacement, one after the other, and the outcomes recorded. What is the probability that at least one
babymother [125]

Answer:

The probability is 0.231

Step-by-step explanation:

In this question, we are tasked with calculating the probability that out of two cards drawn with replacement from a pack of cards , at least one of the two is a face card.

In a standard pack of cards, there are 52 cards.

Now let’s calculate the number of face cards we have.

There are 12 face cards in a pack of cards. There are 4 of each of Jack, Queen or King

The probability of drawing a face card is 12/52 = 3/13

Now, we want to calculate the probability of at least one of the cards drawn are face cards.

Mathematically, what we are needing to calculate is

Probability of drawing a single face card or probability of the two being a face card

Now let’s calculate.

The probability of the first card drawn being a face card is 3/13. The probability of the second card not being a face card will be 1-3/13 = 10/13

The joint probability under this first set of condition will be 3/13 * 10/13 = 30/169

Now, for the second condition, here we are considering that both cards drawn are face cards. What we have is 3/13 * 3/13 = 9/169

Now in probabilities, whenever we are having the statement or, we add the probabilities together

Thus, the probability here would be 30/169 + 9/169 = 39/169 = 3/13

In decimal this will be 0.231

If 6 times a certain number is added to8, the result is 32. Which of the following equations could be used to solve the problem
Alja [10]

This used to confuse me, too. We can use a variable to represent a number we don't know.

In elementary school, you had a problem that said 3 + _ = 8 and you could figure out the blank was 5.

Instead, we have 3 + x = 8 and we can figure out that x = 5.

We can also be given a value for x and asked something like if x = 8, what is x + 7, which we know is 15.

In algebra, when we multiply by a variable, we just say how many of that variable it is. Twelve times a variable is 12x or 12a or 12q, depending on what letter we decide to use to represent our variable.

So, six times a certain number, which we are spparently calling x, is 6x. Adding 8 to that is 6x + 8. Those do not combine to make 14 or 14x because one term has the variable and one does not.

If the result is 32...

6x + 8 = 32

Let's look at the other options.

6x = 32. Where's the 8 added??

6(x + 8) = 32. Well, that looks like it could be it, buuuuut we'd multiply 6 by everything in the parentheses, so this is 6 times the sum of a number and 8 is 32, or 6x + 48 = 32. Not quite.

6x = 8 + 32. That's six times a number equals the sum of 8 and 32, right? Thaaaat's not what it says.
