Answer:
I got 6-7-9-5
Step-by-step explanation:
C and D is 1 more than A and B while having the lowest number, which also means it has the highest number. I started with giving C 9 and subtracting 4 and giving D 5, then I chose 2 numbers between 9 and 5 for A and B. If I gave B 8, then A would have to be 5, but D is already the lowest number so I gave B 7 and A 5 which works out with the requirements. I guess I got lucky when choosing 9 for C, but if 9 didn't work, then I'd go down to 8. I suspected 9 would work because B had to be 7 or 8 while not being the highest number and being less then C and D while being added to A. Make sure to leave feedback!
The answer is
<span>D. y = 4cos(-x) - 2
proof
cosine is an even function, it means cos(-x) = cosx
so </span>y = 4cos(-x) - 2 = y = 4cos(x) - 2
The answer is A, Hope this helps <3... can i have brainlyest?
Answer:
a)5
b)Yes
Step-by-step explanation:
32x4=128
32x5=160
So a equals 5
B it's still the same because 30x5 equals to 150
