Astudent is trying to solve the system of two equations given below:
equation p: y + z = 6
equation q: 8y + 7z = 1
which of the following is a possible step used in eliminating the y-term?
a (y + z = 6) ⋅ −8
b(y + z = 6) ⋅ 7
c (8y + 7z = 1) ⋅ 7
d (8y + 7z = 1) ⋅ 8

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !

Aye asap pls ! markin da brainiest too ! btw da step choices are all add, distribute, divide, n subtract
