So F(6) means 6 on the x axis then look to see where the graph is on the Y axis,
in this case on x 6 y=4
In this problem, you are asked to translate this verbal expression into algebraic expression. Then you must simply this expression if possible.So for this problem, the algebraic expression is:
1.2 ( w + u / 12) -> so simplifying this, will give us:
= 1.2w + 1.2*u/12
= 1.2w + u/10 would be the answer.
X - number of the adults, y - number of children;
The system is:
10 x + 6 y = 3292
x + y = 350 => y = 350 - x
----------------------
10 x + 6 * ( 350 - x ) = 3292
10 x + 2100 - 6 x = 3292
4 x = 3292 - 2100
4 x = 1192
x = 1192 : 4
x = 298
y = 350 - 298
y = 52
Answer:
There were 598 adults and 52 children at the showing.
-5, because subtracting a negative is the same as adding a positive, which will bring -9 up to -5
