The sum of two trinomials is 7x2 - 5x + 4. if one of the trinomials is 3x2 + 2x - 1, then what is the other trinomial?
Margarita [4]

Answer:

  b.  4x^2 -7x +5

Step-by-step explanation:

When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...

  (7x^2 -5x +4) - (3x^2 +2x -1)

  = (7 -3)x^2 +(-5 -2)x +(4 -(-1))

  = 4x^2 -7x +5 . . . . . matches B

Which of the following is equivalent to (Cd) to the fifth power
Rina8888 [55]

Answer:

The 3rd option is correct.

Step-by-step explanation:

This is because of an exponent rule that goes:

(xy)^z = x^z(y^z)

The whole thing gets raised to the power. Therefore only the 3rd one works (ps. if you can mark as brainliest that would be amazing, but if not that's fine)

Aneli [31]

Answer:

y = 5/8x - 3

Step-by-step explanation:

(8,2) and (-8,-8)

m=(y2-y1)/(x2-x1)

m = ( -8 -2)/ (-8 - 8)

m = (-10)/(-16)

m = 5/8

y - y1 = m(x - x1)

y - 2 = 5/8(x - 8)

y - 2 = 5/8x - 5

y = 5/8x - 3
