Answer:

75º

165º

15º

255º

Explanation:

75º because half a circle is equal to 180º.

You know it is 165º because of the same reason.

You get the 15º from knowing that opposite angles are equal.

255º is a case of adding the angles.

If (x)=3x-1 and s(x)=2x+1, which expression is equivalent to r over s (6) ?
katrin [286]

Answer:

\large\boxed{\dfrac{3(6)-1}{2(6)+1}}

Step-by-step explanation:

\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\\text{We have}\\\\f(x)=3x-1,\ g(x)=2x+1\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{3x-1}{2x+1}\\\\\left(\dfrac{f}{g}\right)(6)\to\text{put x = 6 to the equation of the function}\ \left(\dfrac{f}{g}\right)(x):\\\\\left(\dfrac{f}{g}\right)(6)=\dfrac{3(6)-1}{2(6)+1}

I need help with this, I've never really understood linear stuff.
KonstantinChe [14]

You have several possible points (x,y). Any point that lies on the given line will have a y value that you obtain by plugging in the corresponding value of x into the equation of the line.

The line has equation y=-3x+7, so any point on the line will have the form (x,-3x+7).

Among the four given points, there are only 2 different values of x to check. We have

x=4\implies y=-3(4)+7=-12+7=-5

x=1\implies y=-3(1)+7=-3+7=4

which means the given line contains the points (4, -5) and (1, 4). So the answer is A.

PLEASE HELP ME I need an answer
son4ous [18]

Just for you beautiful!


Use distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

(11,-4) is (x1,y1) and (-12,-4) is (x2,y2)

Plug in and simplify

d = sqrt((-12 - 11)^2 + (-4 - -4)^2)

d = sqrt((-23)^2 + (0)^2)

d = sqrt(529 + 0)

d = sqrt(529)

d = 23 (positive because length cannot be negative) ;)
