The maximum value is actually the maximum of y
So, you don't need to care about the stuff inside cosine function,
Cosine function is always within the range of [-1,1]
So here, ymax = -1 + 6* 1 = 5
Answer:
y = 4;
y = 7;
x = 6
Step-by-step explanation:
Given the rule, y = x/2, find the missing values as shown below:
✔️For the first row, to find y, substitute x = 8 into y = x/2,
y = 8/2
y = 4
✔️For the second row, to find y, substitute x = 14 into y = x/2,
y = 14/2
y = 7
✔️For the third row, to find x, substitute y = 3 into y = x/2,
3 = x/2
3*2 = x
6 = x
x = 6
Answer:
x = 3
Step-by-step explanation:
2(4-3x) + 5(2x-3) = 20-5x
8 - 6x + 10x - 15 = 20 - 5x
-6x + 10x + 5x = 20 - 8 + 15
9x = 27
x = 3
4128 divided by 50. The answer is the number of bags
