Step-by-step explanation:
Answer:
the answer is true
Step-by-step explanation:
the x values don't repeat themselves so therefore it is a function
Two polynomials are equal if the coefficients are equal.
Answer:
A. x = -3
B. x = 2
C. x = 9/10
Step-by-step explanation:
(A) –12x + 9 = –15x
Collect like terms
9 = -15x + 12x
9 = -3x
x = 9 / -3
x = -3
(B) 4.5x + 11.5 = 8.5x + 3.5
4.5x - 8.5x = 3.5 - 11.5
-4x = -8
x = -8 / -4
x = 2
(C) 23x – 9 = 13x
-9 = 13x - 23x
-9 = -10x
x = -9 / -10
x = 9/10
Answer:
Standard form for straight line y = m x + b where m is slope
m' = -m or m * m' = -1
answer a or y = - 8/7 + 4 satisfies this requirement
