Simplify the following expressions WILL GIVE BRAINLIEST IF CORRECT! 1. y + y + y + y - 5

2. c (c) + d + d

3. x + x + y + y + y + y + y + 8

Can someone show me the steps to solve the problem?

33% of college students say they use credit cards because of the rewards program. you randomly select 10 college students and ask each to name the reason he or she uses credit cards. find the probability that the number of college students who say they use credit cards because of the rewards program is (a) exactly two, (b) more than two, and (c) between two and five inclusive. if convenient, use technology to find the probabilities.

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
