Solve the system of equations

a + b = 10

a - b = 2

a. a = 5, b = 5

b. a = 2, b = 8

c. a = 6, b = 4

d. a = 3, b = 7

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
