Answer:
[tex]\frac{-1}{8}[/tex]
Step-by-step explanation:
So first find the greatest common factor of the denominators
GCF of 2 , 4 and 8 is 8
Then :
[tex]\frac{-4 + 6 - 3}{8}[/tex]
So you do this to get the above answer:
8 divided by the denominator times the numerator.
You still need to work it out
-4 + 6 = 2
[tex]\frac{2- 3}{8}[/tex]
2 - 3 is -1
Thus the answer is [tex]\frac{-1}{8}[/tex]

What is the domain:
What is the range:
Answer:
Domain: [-4,4]
Range: [-4,6]
Step-by-step explanation:
To domain pertains to the x-coordinates, while the range pertains to the y-coordinates.
Looking at the graph, we can see that the farthest point to the left is (-4,3) and the farthest point to the right is (4,6). Now, we know that the domain is [-4,4].
Looking at the graph, we can see the highest point is (4,6) and the lowest point is (0,-4). Now, we know the range is [-4,6].
Now, we know that the domain is [-4,4] and the range is [-4,6].

The lateral surface area of a cube is 400cm². Its total surface area is
_______
a)600cm² b) 2400cm² c) 500cm² d) 650cm²
Answer:
Step-by-step explanation:
Lateral surface area of cube = 4a²
4a² = 400
a² = 400÷4
a² = 100
a = √100 = √10*10
a = 10 cm
Total surface area = 6a²
= 6 * 10²
= 6* 100
= 600 cm²

What is the slope of the line in the graph?
Answer:
The slope of the line in the graph is 1.
Step-by-step explanation:
Slope is determined by rise over run. Meaning that the number of units the slope goes up/down divided by the number of units the slope goes to the left/right is the slope. The rise is one, and the run is one. 1 over 1 equals 1.
Answer:
The slope of the line is 1.
Step-by-step explanation:
If you can either use rise over run to dtermine the slope or use the point slope formula. For example, take the two points (0,1) and (1,2) using the point slope formula, you'll get 1 in the end.

What is the theoretical probability of rolling a six on a fair six sided die?
Answer:
Probability = Number of desired outcomes ÷ Number of possible outcomes So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. Independent probabilities are calculated using: Probability of both = Probability of outcome one × Probability of outcome two

A figure is located entirely in the third quadrant. If it is reflected over the y-axis, what will the signs of the coordinates be?
Answer:
Step-by-step explanation:
Hello friend!!!
The signs of the coordinates will be ( - , - )
This is because it is located in the third quadrant and the coordinates of any point on the third quadrant are ( - , - )
Hope this helps
plz mark as brainliest!!!!!!!
The signs of the coordinates should be ( - , - )
Signing of the coordinates:Since we know that there are 4 quadrants. In 1st quadrant, the sign is (+,+). In the 2nd quadrant, the sign is (-,+). The 3rd quadrant, the sign is (-,-), And, the fourth quadrant, the sign is (+,-),
So based on this, the above sign should be considered.
