Answer:
The answer to your question is 7 and -1/7
Step-by-step explanation:
Data
First line Second line
B (4, 4) A (0, 1)
M (3.5, 0.5) C (7, 0)
Formula
Slope = m = (y2 - y1) / (x2 - x1)
Process
1.- Calculate the slope of the first-line
x1 = 4 y1 = 4
x2 = 3.5 y2 = 0.5
-Substitution
m = (0.5 - 4) / (3.5 - 4)
-Simplification
m = -3.5 / -0.5
-Result
m = 7
2.- Calculate the slope of the second line
x1 = 0 y1 = 1
x2 = 7 y2 = 0
-Substitution
m = (0 - 1) / (7 - 0)
-Simplification
m = -1/7
-Result
m = -1/7
Answer:
Step-by-step explanation:
A
A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10
We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units
The answer is 96.94 square units.
What must be true is the expression will actually be adding 10 + (+ x), because of the two marks you have to make when subtracting by a negative.
The subtraction sign is also the negative sign. So in this case, the expression is also saying -x, which means there is two negative signs.
A double negative is a positive, so in this case the x will be turned to a positive integer.
If this is still too confusing, she can plug in a number to replace x. Let’s try it with -2:
Ex. 10 - (-2)= 12.
The two negative signs turn into one positive sign, AKA an addition sign. So, the above expression can be simplified as 10 + 2, or 12.
