x= child
2x = adult
6.20x +9.80(2x) =593.40
6.20x +19.6x=593.40
25.80x =593.40
x=593.40/25.80 = 23
23 childrens tickets were sold
Step-by-step explanation:
an open (empty) point means the point itself is not included.
a closed (filled) point means the point itself is included.
the x values going from -3 (not included) to -1 (included) means
-3 < x <= -1
so, the second answer is correct.
The solution is (-4,4)
Explanation: just plug both equations into desmos; the solution is found by looking at where the graphs of 2x+y=-4 and y=-1/2x+2 intersect.
Answer: y= -2x
Step-by-step explanation:
(-3,6)(3,-6)
M= -6-6/3-(-3)
M= -12/6
M= -2
(-3,6 ) and m= -2, find b
Y=mx+b
6=-2(-3)+b
6= 6+b
6-6=b
0=b
Y= -2x
Answer:
Step-by-step explanation:
Since both fractions have a different denominator, we need to look for a common denominator.
Multiply 3 in both numerator and denominator
Hence, 2/9 is the answer
