If y varies inversely as x, and y = 23 when x<br> 8, find y when x 4.
Virty [35]

Answer:

y = 46

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 23 when x = 8 , then

23 = \frac{k}{8} ( multiply both sides by 8 )

184 = k

y = \frac{184}{x} ← equation of variation

When x = 4 , then

y = \frac{184}{4} = 46

Find the factors and zeros of 6x^2 +8x-28=2x^2 + 4
Mice21 [21]

Answer:

First solve the equation:

6x^2 + 8x -28 = 2x^2 + 4

=> 6x^2 - 2x^2 + 8x - 28 -4 = 0 => 4x^2 + 8x - 32 = 0

Extract common factor 4:

=> 4[x^2 + 2x - 8] = 0

Now factor the polynomial:

4(x + 4) (x - 2) = 0

=> the solutions are x + 4 = 0 => x = -4, and x - 2 = 0 => x = 2.

So the answer is the option B: 4(x + 4)(x - 2); {-4, 2}

HOPE THIS HELPS! :D
