Answer:
is one to one mapping, it is not onto mapping
Step-by-step explanation:

f₁(x) is one to one mapping
Let 
f₁(x) = f₁(y):
x₁³ = y₁³
f₁(x) is not onto mapping
Example: If f₁(x) = 7,
x₁³ = 7
![x_{1} = \sqrt[3]{7}](https://tex.z-dn.net/?f=x_%7B1%7D%20%3D%20%5Csqrt%5B3%5D%7B7%7D)
x₁ is not an element of Z
is one to one mapping, it is not onto mapping
Answer:
Factor by grouping
(2x+3) (x-5)
Step-by-step explanation:
Seeing as there are no answer choices, here are all the answers I would think to make. Quick note, associative property of multiplication states that you can change the parenthesis/order of your multiplication in any order and it will stay true, example: (5)(8)(3)=40*3 and 24*5.
Answers: (32)(40)(x), (32)(40x), (32)(8)(5)(x), (32)(8x)(5), (160)(8x), (160x)(8), (160)(8)(x), (32x)(8)(5), (256x)(5), (256)(5x), (256)(5)(x), (1280)(x), (1280x)
C is correct answer.
Skew is a line that does not have a same plane.

Answer:
x = 2 ; y = -1
Step-by-step explanation:
y = 1/2*x - 2 and y = -3*x + 5
1/2*x - 2 = -3*x + 5
7/2*x - 2 = 5
7/2*x = 7
x = 2
y = 1/2*2 - 2 = -1
y = -3*2 + 5 = -1
