Answer:
Beta is 60 degrees, and the angle of A should be 30 degrees.
Step-by-step explanation:
Its a right triangle, so it equals 180 degrees, there's a perpendicular angle at 'C' so its 90 degrees, B and its angle of 'Beta' 60 degrees, and angle 'A' can be 30 degrees. if in need of more explanation please look into complimentary and supplementary angles should give you a good idea.
Answer:
3x-3y+4x+8y
The answer is: 7+5y
Step-by-step explanation:
Graph each points:
f(x) = -13x + 1
when x = 0, y = 1
f(0) = -13(0) + 1
f(0) = 0 + 1
f(0) = 1
when x = 1, y = -14
f(1) = -13(1) + 1
f(1) = -13 + 1
f(1) = -14
when x = 2, y = -25
f(2) = -13(2) + 1
f(2) = -26 + 1
f(2) = -25
etc.
Graph each point and connect them.
I agree. The answer is choice B
=========================================================
f ' (1) is shown to be positive
f ' (2) is shown to be positive as well
There are no critical values between x = 1 and x = 2, so f ' (x) is positive on the interval 1 < x < 2, so f(x) is increasing on this interval
All of this points to either choice A or choice B
--------------------------------
Similarly,
f ' (3) is negative
f ' (4) is negative
so f ' (x) is negative where 3 < x < 4 due to no other critical values being between x = 3 and x = 4
Based on these facts alone, the answer is either choice B or choice D
But we know that it can't be choice D as we determined it was between A and B. This rules out choice D
So all that's left is choice B
Answer:
B)1
Step-by-step explanation:
When you replace x with three your equation is 2*3-5. By doing order of operations you multiply 2*3 and get 6 then subtract 5 getting 1.
