Enter your answer as an ordered triple.
([ ? ],[],[])

(15, 8, 7 )

Step-by-step explanation:

x - y + z = 14 → (1)

y + z = 15 → (2)

z = 7 ← value of z is given

Substitute z = 7 into (2)

y + 7 = 15 ( subtract 7 from both sides )

y = 8

Substitute y = 8, z = 7 into (1)

x - 8 + 7 = 14

x - 1 = 14 ( add 1 to both sides )

x = 15

solution is (15, 8, 7 )

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
