A counterexample for the following would be D, because it is the only positive number, which is opposite of a negative number.
Answer:
y intercept = 4
x intercept = 1/3
<u>x - intercept</u>
To find the x intercept, substitute 0 for y and solve for x.
0 = -12x + 4
0 = -12 (1/3) + 4
0 = -4 + 4
0 = 0
The x - intercept is 1/3
<u>y - intercept</u>
To find the y intercept, substitute 0 for x and solve for y.
y = -12 (0) + 4
y = 0 + 4
y = 4
The y - intercept is 4.
I think you have mistaken the formula.
I will do it this way.
Interest after 6 years: 1.038^6 × $5,000
Thus, amount after 6 years = $6,253.95
Step-by-step explanation:
Given
5x + 2x + 2 = 9x + 4
9x - 5x - 2x = 2 - 4
9x - 7x = - 2
2x = - 2
x = - 2 / 2
Therefore x = -1.
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
