Given the domain {-2, 1, 5}, what is the range for the relation 4x + y = 3? {11, -1, -17} {-1, 4, 8} {-5, 7, 23} {-11, 1, 17}

Which of the following represents the factorization of the trinomial below? x^2+7x-30

Astudent must have an average on five test that is greater than it equal to 80% but less than 90% to receive a final grade of b. devon's greades on the first four test were 78% 62% 91% and 80% what range if grades on the fifth test would give him a b in the course? ( assuming the highest grade is 100%)

Idon't get undoing if its pass adding and subtracting so can someone ? x-2 over 5 = 18
