Given ,

$f(x) = 3x^{2} + x -2$

Now ,

$f(-2) = 3(-2)^{2} +(-2)-2$

=> f(-2) = 8-4 = 4

The value of x that satisfies the equation 4/3=x+10/15

kenny6666 [7]

For this case we must find the value of "x" that meets the following equation:

$\frac {4} {3} = x + \frac {10} {15}$

We subtract $\frac {10} {15}$ on both sides of the equation:

$\frac {4} {3} - \frac {10} {15} = x\\\frac {15 * 4-3 * 10} {3 * 15} = x\\\frac {60-30} {45} = x\\- \frac {30} {45} = x$

We simplify:

$x =\frac {6} {9}=\frac{2}{3}$

Finally, $x =\frac {2} {3}$

Answer:

$x =\frac {2} {3}$
