How do you solve for a y and x intercept?

Mathematics
1 answer:
FrozenT [24]3 years ago
3 0

For a y-intercept, set x = 0 in your equation. Remember that a y-intercept intercepts the y-axis, which is found at x = 0. Thus, setting x = 0 will give you the place where your equation intercepts the y-axis.


For an x-intercept, do the opposite, set y = 0. This is because the x-axis is found at y = 0. Similar to the y-intercept, this will find you the point where your equation intercepts the x-axis.

The pattern they're looking for in the uppermost question is 0,2,6,14,30,62.

The second problem shows the Fibonacci sequence.  Each number is the sum of the two numbers before it.  So:

2,3,5,8,13,21,34

34 are the number of miles she'll run on Week 8.  

The equation on the bottom right is M = 5p.  The first two numbers in the function table are 25 and 50.

A cash box of $1 and $5 bills is worth $45. The number of $1 bills is three more than the number of $5 bills. How many of each b
Softa [21]

Answer:

  • 7 $5 bills
  • 10 $1 bills

Step-by-step explanation:

If we take out the extra $3, we can group the bills into one each of $5 and $1, for a value of $6. There will be 7 such groups in the remaining $42.

That means there are 7 bills of the $5 denomination, and 3 more than that (10 bills) of the $1 denomination.

There are 7 $5 bills and 10 $1 bills.

_____

If you want to write an equation, it is usually best to let a variable stand for the most-valuable contributor. Here, we can let x represent then number of $5 bills. Then the value of the cash box is ...

  5x +(x+3) = 45

  6x = 42 . . . . . . . . subtract 3, collect terms

  x = 7 . . . . . . . . . . . there are 7 $5 bills

  x+3 = 10 . . . . . . . . there are 10 $1 bills

You may notice that this working parallels the verbal description above. (After we subtract $3, x is the number of $6 groups.)

Suppose P( A) = 0.60, P( B) = 0.85, and A and B are independent. The probability of the complement of the event ( A and B) is: a
diamong [38]

Answer: a. 0.4 × 0.15 = 0.060

Step-by-step explanation: Probability of the complement of an event is the one that is not part of the event.

For P(A):

P(A') = 1 - 0.6

P(A') = 0.4

For P(B):

P(B') = 1 - 0.85

P(B') = 0.15

To determine probability of A' and B':

P(A' and B') = P(A')*P(B')

P(A' and B') = 0.4*0.15

P(A' and B') = 0.06

<u>Probability of the complement of the event is 0.060</u>
