Answer:
y = -7; x = 4
Step-by-step explanation:
x - 7y = 53
x = 7y + 53
-4x - 5y = 19
-4(7y + 53) - 5y = 19
-28y - 212 - 5y = 19
-33y = 231
-11y = 77
y = -7
x - 7(-7) = 53
x + 49 = 53
x = 4
Answer: a) b)
Step-by-step explanation:
Since we have given that
Number of men = 4
Number of women = 2
So, number of selected people = 2
So, the probability that both officers are women would be
And the probability that at least one of the two officers is a woman would be
Hence, a) b)
Answer:
5/6
Step-by-step explanation:
1/2 + 1/3 need a common denominator to add them up.
1/2 is the same as 3/6.
1/3 is the sane as 2/6.
3/6 + 2/6
Add the tops, but keep the same denominator.
3/6 + 2/6 = 5/6
5/6 cannot be simplified, so that's the answer. That's how you do it! Hope this helps!
You can put f(x) = -12x into a graphing calculator like desmos and it'll show you the graph :)
G(x) = sqrt(x + 3) is obtained from f(x) = sqrt(x) by shifting the graph of f, 3 units to the left.
