Answer:
b. angle K is acute
Step-by-step explanation:
We're often told not to draw any conclusions from the appearance of a figure in a geometry problem. Here, angle K appears to be somewhat less than 90°, so angle K is acute.

<em>Additional comment</em>
This choice of answer is confirmed by the fact that the other two (visible) choices say the same thing. If one of them is correct, so is the other one. Hence they must both be incorrect. (An obtuse angle is more than 90°.)
Answer: 56ways
Step-by-step explanation:
given data:
total beans = 9
blue beans = 6
red beans = 1
yellow beans = 1
green beans = 1
solution:
This is a permutation problem because there is a condition attached to it which states that the beans most be arranged in a way that atleast each none blue has a blue bean on its side when shared.
= ( r + n - 1 ! ) / r ! ( n - 1 )!
= 3 + 6 - 1 / 3! ( 6-1 )!
= 8! / 3! x 5!
= 40320/ 720
= 56 ways
Answer:
x = 7, y = 30 and x = 3, y = 10
Step-by-step explanation:
5x - y = 5, then y = 5x - 5
2y - x^2 = 11
2(5x - 5) - x^2 = 11
10x - 10 - x^2 = 11
-x^2 + 10x -10 = 11
-x^2 + 10x -21 = 0
x^2 - 10x + 21 = 0
(x - 7)(x - 3) = 0
x = 7, y = 30
x = 3, y = 10

Therefore, using the <u>identities</u>, the given expression can be <em>simplified</em> as follows:
Well, a y-intercept is a the point on a graph where the x value equals 0, because the point sits exactly on the y-axis. In this case, the y-intercept would be (0, -9).
