Is (0,0) a solution to this system?<br> ys x2 - 4<br> y&gt; 2x-1
kow [346]

Answer:

C

Step-by-step explanation:

Ok, so to do this, we are just going to plug in (0,0) and see it it checks out.

Let's take the first question. yy\geq x^{2} -4

When we plug (0,0) into this, we get the following

0\leq 0^{2} -4

0\leq 0-4

0\leq -4

This is false.

Let's check the other equation:

0>2(0)-1\\0>0-1\\0>-1

This is true.

So the correct answer is C

Answer:

38.4895

Step-by-step explanation:

area of circle = pi * r^2

3.142 * 7^2 = area of the whole circle

as we only have 1/4 of the circle we divide our area by 4

(3.142 *7^2) / 4 = 38.4895

630<br> Solve for &lt;2.<br> *2 = [?]°<br> 142<br> 57°123°<br> please explain as well
AlexFokin [52]

Step-by-step explanation:

the total angles in the triangle are 180°

so,

63° + 57° + ∠2 = 180°

120° + ∠2 = 180°

∠2 = 180° - 120°

∠2 = 60°
