Answer:
0 = 4x
Step-by-step explanation:
-2(2 - 2x) = 4 - 8(1 - x)
-4 + 4x = 4 - 8 + 8x
-4 + 4x = -4 + 8x
-4 + 4 = 8x - 4x
0 = 4x
Answer: The measure of the vertex angle = 80°
Step-by-step explanation:
Angle sum property of triangle : The sum of the measures of the angles for any triangle is 180 degrees.
So,
'
Then, vertex angle = 
Hence, The measure of the vertex angle = 80°
Answer:
Well, it's pretty simple. If your reflecting something over the y axis the X will change if it's negative or positive. So if it's -x and you flip it over it becomes a positive x. If you flip it over the x-axis the Y is the one that change to a negative or positive.
So if the shape flips over the y-axis, the X points will turn negative. for example, one of the points is (1,4) it will turn to (-1,4)
Step-by-step explanation:
So your present value is 7750. this is what you have now. they give you the intesrest rate which is 4% and how the amount of year is 5.
recall the formula for a compounded continously is
P×e^(r×t)
the answer is 7750×e^(.04×5)
2(x+4)=18
2•x + 2•4 = 18
2x + 8 = 18
2x + 8 = 18
- 8 -8
