Answer:
for the system of linear equations, the answer would be (-8/3,2) and only have one solution
Parallel lines have no solution
Step-by-step explanation:
Answer:
Question 1: 18
Question 2: 31.5
Step-by-step explanation:
1/2*b*h=Area for a parallelogram
1/2*12*3=18
1/2*14*3.5=31.5
Area of the sector = 90/360 ×πr^2
=1/4 ×3.142×6×6
=1/4×113.112
=28.278kilometers square
Approximately 28kilometers square
Now get the square root of 30
The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
