Answer:
y = -3, x = 5
Step-by-step explanation:
In the first equation, x = 2 - y, x is on one side. So we can try to isolate the variable x in the second equation by adding 2y + 11 on both sides to get:
x = 2y + 11
So now we have equations x = 2 - y and x = 2y + 11. Therefore 2 - y = 2y + 11. Now we isolate variable y by adding y on both sides and subtracting 11 on both sides to get -9 = 3y. Divide by 3 on both sides to get y = -3.
Let's substitute that into x = 2 - y. Since y = -3, we now have x = 2 - (-3) = 5.
Required interval is (0.42 x 128523, 0.78 x 128523) = (53980, 100,248)
Answer:
See below
Step-by-step explanation:
With center , h,k given as 3,2
standard form is
(x-3)^2 + ( y-2)^2 = r^2
r^2 is distance from center to point given
distance formula r^2 = ( 3-5)^2 + (2-4)^2
r^2 = 8
so the equation is then (x-3)^2 + (y-2)^2 = 8

Since There are 6 marbles in total and possibly one red marble than its 1/6.
Im not sure if that makes sense but i hope it does :)
The cost of 8 Concert Tickets is $290
Step-by-step explanation:
Five concert tickets cost = $181.25.
The cost of 8 concert tickets = ?
Now,
181.25 ÷ 5 = 36.25
Here, We get the value of one concert ticket is $36.25
Now, For 8 Concert Tickets
8 × 36.25 = 290
Thus, The cost of 8 Concert Tickets is $290
