Answer:
Step-by-step explanation:
if to substitute the coordinates of the point into the equation:
2*(-3)=2*a-7, then a=1/2
Y=mX+B do you know also need to know what they stand for
Answer:
b = 22
Step-by-step explanation:
Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle. We want to find the value of b. We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:
sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22
Answer:The answer is 375
Step-by-step explanation:Jonas drawing is 8 inches wide.He wants to make a poster which is 30 inches wide.The library copier will have to zoom the drawing 30 ÷ 8 = 3.75 times to make the poster.So the zoom factor button is times 3.75 button.
Top:
x / (x + 1) - 1 / x
= [x^2 - (x +1)] / x(x+1)
= (x^2 - x - 1 ) / x (x+1)
Bottom:
x / (x + 1) + 1 / x
= [x^2 + (x +1)] / x(x+1)
= (x^2 + x + 1 ) / x (x+1)
Now you have:
(x^2 - x - 1 ) / x (x+1)
----------------------------
(x^2 + x + 1 ) / x (x+1)
= (x^2 - x - 1 ) / x (x+1) * x (x+1) / (x^2 + x + 1 )
= (x^2 - x - 1 ) /(x^2 + x + 1 )
Answer:
x^2 - x - 1
---------------------
x^2 + x + 1
