Answer:
answer is 0
Step-by-step explanation:
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
Answer:
The ratio for sin(X) is 
The ratio for cos(X) is 
Step-by-step explanation:
- The ratio of the sine of a right triangle is:
Since we need the ratio for angle X, 
. From the picture we can infer that the opposite side of X is 
. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:
- The ratio of the cosine is:
Similarly, , adjacent side = 5, and hypotenuse = 12, so
Answer:
144/2 = 72
72/2 = 36
36/2 = 18
18 /2 = 9
so jeremy has 9 marbles left
1 min = 60 s;
24 min = 24 x 60 s = 1440 s;
__________________________
1h = 60 min = 3600s;
2h = 7200s;
2h 17 min = ( 3600 + 17x60 ) s = ( 3600 + 1120 )s = 4720s;
___________________________________________________
1zi = 24h = 1440 min = 86400s;
2h = 7200s;
15min = 900s;
1zi2h15min = (86400 + 7200 + 900)s = 94500s;
