Answer:
Hi there, this should be the correct answer!
x = -1 - 1/2y
y = -2 - 2x
Step-by-step explanation:
Work I did, hope this helps:
y + 4 = -2x + 2
y + 2x = -2
2x = -2 - y
x = -1 - 1/2y
y = -2 -2x
Hope this helped!
Recall the double/half angle formulas:
We're given , and since is between π/2 and π, we expect to be negative. So from the Pythagorean identity, we find
Also, we know will fall between π/4 and π/2, so both and will be positive. Then we find
and it follows that
Answer:
its C
Step-by-step explanation:
Answer: 792
Step-by-step explanation:
Given : Hugo and Viviana work in an office with ten other coworkers.
Out of these 12 workers, their boss needs to choose a group of five to work together on a project.
The combination of n thing taking m at a time is given by :-
Then, the number of different working groups of five the boss can choose :-
Hence, the number of different working groups of five the boss can choose = 792.
Answer:
<h3>B 40</h3><h3>C 30</h3><h3>E 55</h3><h3>By the Triangle Inequality Theorem, the range of possible lengths of the third side is 0 < x < <u>28</u>.</h3><h3>So, the perimeter for all possible triangles must be greater than <u>28 units</u> and less than <u>56 units</u>.</h3>
Step-by-step explanation:
We are given an isosceles triangle has legs with length 14 units.
Therefore, another equal side would also be equal to 14 units.
Sum of two equal sides = 14+14 = 28 units.
Therefore, third sides would be less than 28 inches.
So, the perimeter of the triangle could be
28+28 = 56 that is less than 56 but greater than 28.
So, we could choose options B and C.
