Answer:

I would probably guess B.

Step-by-step explanation:

because the first row is x + 2 = y,

the second row is x + 3 = y,

the third is x + 4 = y,

the fourth is x + 6 = y,

so there is no pattern, therefore is is not D.

For A, the ratios are equal, but this is not the case for 4/7, so it can't be A.

C doesn't make sense, because some pairs are simplified, like the first two, but the last two are not.

So, you can make your own choice.

How does sin 30 compare to sin -30

Kisachek [45]

Answer:

c. sin 30 is positive and sin -30 is negative

Step-by-step explanation:

Picture the unit circle (which is attached). Sine is like the y-coordinate. And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a negative y-coordinate. 30 is above the x-axis, so it has a positive y-coordinate.

Math queztion -8x + 40> -16 =

emmainna [20.7K]

Answer: x < 7

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is -8x by subtracting 40 from both sides.

That leaves you with -8x > -56.

To get x by itself, divide both sides by -8 but watch out.

If you divide both sides of an inequality by a negative,

you must switch the direction of the inequality sign.

So we have x < 7.
