If y varies directly as the x^2 and y = 200 when x = 5, what is the value of y when x = -3?
gayaneshka [121]
As the variation is direct we have:
 y = kx ^ 2

 We must find the value of k.
 For this, we use the following data:
 y = 200 when x = 5
 Substituting values we have:
 200 = k5 ^ 2

 Clearing k:
 k = 200/5 ^ 2

k = 200/25

k = 8
 Then, the function is:
 y = 8x ^ 2

 We evaluate the function for x = -3
 y = 8 (-3) ^ 2

y = 8 (9)

y = 72
 Answer:
 the value of y when x = -3 is:
 c.

1/4 + 1/2 + x = −3/4
Ostrovityanka [42]

1/4 + 1/2 + x = −3/4

get a common denominator 1/4

1/4 +2/4 +x = -3/4

combine like terms

3/4 +x =-3/4

subtract 3/4 from each side

x = -3/4 -3/4

x = -6/4

divide top and bottom by 2

x = -3/2

x = -1   1/2

Answer : x = -1  1/2

Hey can you please help! posted picture of question
frosja888 [35]
The solution of the system can be x - 3y = 4 only if both the equations can be simplified to x - 3y = 4.

This will mean that both the equations will result in the same line which is x - 3y = 4 and thus have infinitely many solutions.

Second equation is:

Qx - 6y = 8 
Taking 2 common we get:

(Q/2)x - 3y = 4

Comparing this equation to x- 3y = 4, we can say that 

Q/2 = 1
So,
Q = 2

Therefore, the second equation will be:

2x - 6y = 8
