Marie was trying to show her friend why -3 -8 equals a positive product. This is what she wrote:
-3 x 0 = 0
-3 × (?) = 0
-3(8) +-3(-8) = 0
-24 + 24 = 0
What should Marie write in place of the question mark?
OA) 8 + 8
OB) -8 + (-8)
OC) 8 + (-8)
OD)-8 + 0
Answer:
8+8=16
-8 + (-8)= - 16
8+ (-8)=0
-8 + 0 = - 8

True or False? (-x)^6 = -x^5 Explain your
answer (use either words or an example).
Answer:
False
Step-by-step explanation:
[tex](-x)^{6}[/tex] = [tex]x^{6}[/tex]
- [tex]x^{5}[/tex] = - [tex]x^{5}[/tex]
Thus
[tex](-x)^{6}[/tex] ≠ - [tex]x^{5}[/tex]

What is the equation of the line that passes through the point (2, -1) and has a slope of 3/2?
Answer:x=-2
Step-by-step explanation: -1=3/2x+2
Given :-
A line having a slope of 3/2 passes through (2,-1) .
To Find :-
The equation of the line .
Answer :-
According to the question ,
m = 3/2
Point = (2,-1)
We know Point slope form of the line as ,
y - y¡ = m ( x - x ¡ )
Substitute ,
y - (-1) = 3/2 ( x - 2 )
y + 1 = 3/2x - 3/2*2
y +1 = 3/2x - 3
2( y +1) = 3/2x *2 - 3*2
2y + 2 = 3x - 6
3x -2y -8 = 0

Question 1. √80/6 Question 2. (2√5)^2
Answer:
Q1: is 0
Q2: is 20
Step-by-step explanation:
Q1: Divide the numbers 0 ÷ 6 = 0
√8 × 0
√8 = 2√2
2 × 0 × √2
Apply rule 0 × a = 0
Q2: Apply exponent rule : (a × b)^n = a^n b^n
2^2(√5)^2 = 2^2 (√5)^2
2^2 = 4
4 (√5)2
(√5)^2 = 5
4 × 5
Multiply the numbers: 4 × 5 = 20

1. Brie knows there is a relationship between the grades on
her math tests and the time she spends studying for those
tests. Identify the independent quantity and the dependent
quantity in this problem situation.
Time is the independent variable as it can be treated as a controllable constant against which changes in a system can be measured. How much time you spend effects how much time you study, making studying the dependent.
