Answer:
1 liter of milk
Step-by-step explanation:
10%= 1/10
since the number we are taking 1/10 of <u>is</u> 10, we find one out of ten, which is of course 1.
Summer because you normal have a vacation in the summer
3x^2-6x+5
for ax^2+bx+c=0
discriminant is b^2-4ac
when
1. b^2-4ac>0, there are 2 real roots
2. b^2-4ac=0, there is 1 real root
3. b^2-4ac<0, there are 2 complex roots
3x^2-6x+5
a=3
b=-6
c=5
(-6)^2-4(3)(5)
36-60
-24
answer is -24 is the discriminant
Answer:
Senior citizen tickets = 9
Student tickets = 10
Step-by-step explanation:
We begin by converting the question into simultaneous linear equations;
Senior citizen tickets = a
Student tickets = b
4a + 6b = 96
8a + 13b = 202
to find a,
if 4a +6b = 96
a = 96/4 - 6b/4
a = 24 - 1.5b
We now substitute this into the second equation
8(24 - 1.5b) + 13b = 202
192 - 12b + 13b = 202
b = 202 - 192
b = 10
We now put the value of b in either equation
4a + 6b = 96
4a + 6(10) = 96
4a + 60 = 96
4a = 96 - 60
4a = 36
a = 9
To solve this we are going to graph each one of the system of equations. The points in which the graphs of the tow equations intercepts will be the real solutions of the system of equations.
System A. Since the graph of the equations intercepts two times, we can conclude that the system has
2 real solutions.
System B. Since the graph of the equation don't intercept, we can conclude that the system has
0 real solutions.
System C. Since the graph of the equations intercepts two times, we can conclude that the system has
2 real solutions.
