Please! I will give brainiest! Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2^-X and y = 4^x + 3 intersect are the solutions of the equation
2^-x= 4^x+3.

Part B: Make tables to find the solution to 2^-X = 4^x + 3 Take the integer values of x only between -3 and 3. (4 points)

Part C: How can you solve the equation 2^-X = 4^x + 3 graphically?

Will give brainliest series to sigma notation write the following series in sigma notation. 6+10+14+18+22+26+30 example image shown below.

2people are trying different phones to see which one has the better talk time. chatlong has an average of 18 hours with a standard deviation of 2 hours and talk-a-lot has an average of 20 hours with a standard deviation of 3. the two people who tested their phones both got 20 hours of use on their phones. for the z-scores i got 1 for the chatlong company and 0 for talk-a-lot. what is the percentile for each z-score?

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
