Answer:
15
Step-by-step explanation:
3x - 2y = ?
3(7) - 2(3) = ?
21 - 6 = ?
= 15
All you have to do is substitute the given values & follow the order of operations! Best of luck.
Answer:
a) is B because it inrease quite rapidly and then slowly increase
b) is c as it increase and then decreases quite soon and rapid and then increase quite rapidly again
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Since the y-values are the same, you calculate the absolute value of -5 - 4. That is 9.
for f(x) = -2(x-4)2+2 - set equation to y = -2(x-4)2+2, solve x-4=0, x = 4
axis of symmetry is x = 4
for g(x) = 5x2-10x+7, set equation to y = 5x2-10x+7, solve the square: 5x2 becomes 5(x-1)2 solve x-1 = 0, x = 1
axis of symmetry is x=1
for H(x) what x value would be the centerline so that the graph symmetry is the same on both sides? looking at the graph the top of the arc is on -2
so axis of symmetry is x = -2
Answer:
769.46 miles
Step-by-step explanation:
Please have a look at the photo attached in this answer
The missing part of the angle is 32 degrees, so the total angle of B is:
32 + 73 = 105 degrees.
Let x is the distance from airport A to airport C to the nearest tenth of a mile, we use cosine law to find x:
= 
- 2(570)(390)cos(105)
<=> = 592070
<=> x = 
= 769.46 miles
