What are the solutions of the following system 10x^2 - y = 48 2y = 16x^2 + 48

The Correct answer is C. (6, 312) and (–6, 312)

Given the following system:    and

we can write it as:

               .......[1]

Substitute this in equation   we get;

or

Subtract from both sides of an equation:

or

or

Simplify:

⇒ x = 6 , -6

Now, substituting these x values in equation [1];

for x =6

or

=360-48 = 312

Similarly for, x = -6

or

=360-48 = 312

So, we have the solution of the given following system; (6,312) and (-6,312).

step-by-step explanation:

30% of 170 is 51. 170+51=221

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
