angles a and b are supplementary because they form a straight line
2+tan ×[-pi/4
2×10=20×16=[pi/320
Answer:
two (n = 4, and n = -1)
Step-by-step explanation:
Let's solve it as follows:
First, we can divide out the common factor of 3 from each side, to get:
n(2n-8) = 8 -2n
Next, we expand, and move all the terms over to the right hand side (so that we have 0 on the LHS - as this is how we will want to solve the quadratic equation):
2n^2 - 8n - 8 +2n = 0
2n^2 - 6n - 8 = 0.
We also see we can further simplify by dividing out the factor of 2, to get:
n^2 -3n -4. = 0
Next, as this is a quadratic, the usual next step is to factorise, to get:
(n-4)(n+1) = 0
So we see that n = 4 and n = -1 are the two solutions.
Answer:
f(x) = 6x-16
Step-by-step explanation:
Since the function is shifting 4 units down, it will be moving down the y axis, meaning the y-intercept will decrease by 4.
y=mx+b is the formula for the straight line, where b is the y-intercept. The y-intercept in this function is -12, so we would just subtract -4 from -12 to get our answer.
-12-4=-16
Make sure to leave the coefficient of x
Therefore, f(x) = 6x-16
I suppose this is in reference to the chance?
The chance of choosing either red or blue marbles is 50/50 considering that there if four of each type in the bag.
The person chose 2 times, and each time go a red marble. The chance of choosing either is still 50% and they are both equally likely to get chosen.
