PLEASE HELP I NEED IT ASAP The ordered pair (x, y)=(8, 6) is the solution of the following system of linear equations

x = 1/10y + a
y= 1/10x + b
Find the value of a + b.

The accompanying data represent the miles per gallon of a random sample of cars with a three-cylinder, 1.0 liter engine. (a) compute the z-score corresponding to the individual who obtained 42.342.3 miles per gallon. interpret this result.

The first four terms of a sequence are shown on the graph below. what can be concluded about the sequence? the common ratio of the sequence is 2. the common difference of the sequence is 2. the next term of the sequence is represented by the point (5, 64). the next term of the sequence is represented by the point (5, –64).
