Can someone help me with this problem?
dlinn [17]

Answer

7 or 4

because do you see how v is lined 2 I don't remember if you times or divide .I'm going to go with times.

So what is 2 x 10 since V=10

2 x 10=20

Then we are going to divide so what is 20 divided by 5 since e=5

20 divided by 5=4

Next our last step what is 4 + 3=7 and there's are answer.

The answer is divide then this would be the answer.

so V(10) divided by 2=5  divided by e(5) =1 + 3=4

Hope this helps have a great day

HELP QUICKLY PLEASE!!! for y = 3x - 2x^2 + 5x^3, show how to find the value for y, when x = 3. please show your work.
Brrunno [24]
All you need to do is plug in 3 wherever you see an x!
y = 3(3) - 2(3)^2 + 5(3)^3
y = 9 - 2(9) + 5(27)
y = 9 - 18 + 135
y = -9 + 135
y = 126
Hope this helps!
