Answer:

1. I don't know how to solve that sorry :(

2. B. It is a diameter

3. 30° = q

4. I don't know sorry :(

Step-by-step explanation:

1. I don't know how to solve that sorry :(

-----------------------------------------------------------

2. B. It is a diameter

------------------------------------

3. All triangles = 180°

180° = 60° + 90° + q

180° = 150° + q

180° - 150° = 150° - 150° + q

30° = q

180° = 60° + 90° + 30°

180° = 150° + 30°

180° = 180°

4. I don't know sorry :(

ASHA 777 [7]

Answer:

(-6,4)

Step-by-step explanation:

The equations are:

$x^2+4y^2=100\\4y-x^2=-20$

Solving for x^2 of the 2nd equation and putting that in place of x^2 in the 2nd equation we have:

$4y-x^2=-20\\x^2=4y+20\\-------\\x^2+4y^2=100\\4y+20+4y^2=100$

Now we can solve for y:

$4y+20+4y^2=100\\4y^2+4y-80=0\\y^2+y-20=0\\(y+5)(y-4)=0\\y=4,-5$

So plugging in y = 4 into an equation and solving for x, we have:

$x^2=4y+20\\x=+-\sqrt{4y+20} \\x=+-\sqrt{4(4)+20} \\x=+-\sqrt{36} \\x=6,-6$

So y = 4 corresponds to x = 6 & x = -6

The pairs would be

(6,4) & (-6,4)

we see that (-6,4) falls in the 2nd quadrant, thus this is the solution we are looking for.

PLS HELP ASAP STUMPED ON THIS ONE!!!!!!! ?/? ÷ 5 = 12/50

Svet_ta [14]

Answer:

6/5 or 1.2

Step-by-step explanation:

you can solve with an equation:

x : 5 = 12 : 50

x = 5 * 12 : 50

x = 6/5 (or 1.2)

or you can solve with an expression

12/50 * 5 = 6/5 (or 1.2)

Simplify the following expression: '5x - 8 + 3y + 10x - 8y'

monitta

Answer:

-5x-8-11y

Step-by-step

Because you shift 10x to -10x and then 5x-10x = -5x

You leave the -8 the same

You do 3y to -3y and then do -3y -8y = -11y

Hence altogether you get, -5x -8 -11y
