Answer: (0,3)
Step-by-step explanation: To find the x-value of the vertex for any quadratic, you can use the formula -b/2a. In this case, there is no clear b, but you can think of it like y=-x^2 +0x+3 so in the form ax^2 + bx +c, b=0. Therefore the x-value is 0/ -2, or 0. So we know the vertex is (0, y). To find y, just plug 0 into the original equation for x, getting you y=0+3, so y=3, so the vertex is (0,3)

Answer:
3. adjacent; 49
4. adjacent; 71
5. verticle; 41
6. adjacent; 14
Step-by-step explanation:
ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.
to find 3:
set both equations equal to each other and solve because verticle angles are equal
to find 4:
add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem
