Y = –3x + 5 y = mx + b Which values of m and b will create a system of linear equations with no solution? m = –3 and b = –3 m = 5 and b = –3 m = 3 and b = 5 m = -3 and b = 5

(A) m = –3 and b = –3

Step-by-step explanation:

If m=–3 and b=–3

The system of linear equations:

y = –3x + 5

y = mx + b

Becomes

y = –3x + 5 (i)

y = –3x – 3   (ii)

Notice that 5 is added to -3x in (i) and -3 is added to -3x in (ii) and both equals y. This is impossible. Thus the system has no solution.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
