Hmm all of them have the chance to be chosen but u got to aim of what u want to get
Answer:
(6,8)
Step-by-step explanation:
2x + y = 20
6x - 5y = -4
Multiply the first equation by -3
-3(2x + y) = -3*20
-6x -3y = -60
Add this to the second equation
-6x-3y = -60
6x - 5y = -4
--------------------
-8y = -64
Divide each side by -8
-8y/-8 = -64/-8
y = 8
Now find x
2x+y = 20
2x +8 = 20
2x+8-8 = 20-8
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
(6,8)
Answer:
a=-6
Step-by-step explanation:
p^a=1/p^6
= p^-6 ( a^-b=1/a^b)
since p^a=p^-6
a= -6
When reflecting something across the y axis, the x point becomes of the opposite parity (for example, when reflecting (1,2) across the y axis, the result would be (-1,2)). In this case, we can start by doing this for each of the individual points.
J (1,4) becomes (-1,4) when reflected across the y axis
R (2,1) becomes (-2,1) when reflected across the y axis
A (3,5) becomes (-3,5) when reflected across the y axis
So, I think that your mistake was that you thought that reflecting across the y axis meant changing the y coordinate. That being said, the correct answer is A.
<span>A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.</span>
