Answer:
The answer is D
Step-by-step explanation:
took the test<//3
A slope of 3 means the gradient is 3 so we get y=3x+c as derived from the linear formula. we then sub in x=2 and y=-0.5. this gives us c=-6.5.
The equation would be y=3x-6.5
I think this is right.
Answer: Any equation that has a -5 before the x will have the same slope. Some examples could be:
y= -5x
y = -5x + 100
y = -5x - 3
For reference, one full circle is 360 degrees or 2pi radians.
If we were to convert 360 degrees to radians, we could set up the following equation:
360k = 2pi
where k is a constant. By solving for k, we can find what value we must multiply any angle in degrees by to get its radian counterpart.
Divide both sides by 360:
k = 2pi/360
Reduce:
k = pi/180
So to convert an angle from degrees to radians, multiply it by pi/180. For example, 120 degrees would be:
120 * pi/180 = 2pi/3 radians
Answer:
168
Step-by-step explanation:
Multiply 21 by 8 so
21 × 8 = 168
