So for something to be perpendicular the gradient must be the negative reciprocal of your original line so your original gradient is 2 so your new gradient will be -1/2. Then you have y = -1/2 x + c . Now you substitute this into the point (4,-1) to get -1 = -1/2 x 4 + c and -1/2 x 4 = -2 so you have -1 = -2 + c so c = 1 so then you put the equation together to get y = -1/2 x + 1
Hope this helps :))
Explain a little bit deeper and i would love to help
Answer: B. An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles. dd
Step-by-step explanation:
An isosceles is a triangle that has two sides of equal length.
The isosceles theorem says that the angles opposite to the equal sides of a triangle are equal.
Thus, it also has two equal angles and one non equal angle. Thus, it does not have all congruent angles.
- The order of rotational symmetry of a figure is the number of times we rotate up to 360° the figure such that it looks exactly the same as the original figure.
When we rotate the isosceles triangle up to 360° , only 1 time it looks exactly same as in the beginning because at each rotation the order of angles changes.
Therefore, An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.
Answer:
100
Step-by-step explanation:
if SP>CP,
It is profit [SP - CP = Profit]
if CP>SP,
It is loss [CP - SP = Loss]
Here in the question CP>SP so,
loss = CP - SP
=200 - 100
= 100
Answer:
C. (g − f)x
Step-by-step explanation: Subtract costs (f) from revenue (g) and multiply by bouquets made (x) to find profit.
Example would be if it costs $1 to make each bouquet and she charges $3 for each bouquet made. If she made 5 and sold them it would be...
(g-f)x
(3 - 1) 5 = profit
(2) 5 = $10 profit
