Answer:
X-intercept = -3 and y-intercept = 6
Step-by-step explanation:
We can start off by isolating the y term. To do that, we must add 2y to both sides to get
Now, we must add 12 to both sides and the y term will be all alone on the right side:
Now, to have only y on the right side, we must divide by 2 to get:
In slope-intercept form, b is the y-intercept, and 'b' in this equation is 6. We have our y-intercept.
To find our x-intercept, y must be equal to zero. We can plug in that value for y and solve for x:
We can start off by subtracting 6 from both sides to get:
We can then divide both sides to get when y is equal to 0. Thus, we have our x-intercept.
Answer:
- a. 1 / 13
- b. 3 / 13
- c. 10 / 13
Step-by-step explanation:
<h3>a.</h3>There are four 5's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 5. This means that the probability will be:
For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:
The total possible cards are, still, 52, so, the probability will be
We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face car its:
so
but, we know that
so
