Ryker is given the graph of the function y= 1/2x^2 - 4 . He wants to find the zeros of the function but is unable to read them e

REY [17]

$y = \frac{1}{2x^{2} - 4}$
$0 = \frac{1}{2x^{2} - 4}$
$0(2x^{2} - 4) = (2x - 4)(\frac{1}{2x^{2} - 4})$
$0(2x^{2}) - 0(4) = 1$
$0 - 0 = 1$
$0\neq1$

Please help ! :0 <br><br> -17 = 2y/3 + 3y/4

VashaNatasha [74]

Hi,

Equation;

$- 17 = \frac{2y}{3} + \frac{3y}{4}$

Solving:

$- 17 = \frac{2y}{3} + \frac{3y}{4} \: \: \: | \div 12 \\ - 204 = 8y + 9y \\ - 204 = 17y \\ 17y = - 204 \: \: \: | \div 17 \\ \\ y = - 12 \: \: \: \: \: \: \: \: (result)$

Hope this helps.

Four more than a number is no more than thirteen

statuscvo [17]

The equation would be 4+x $\leq$ 13.
Subtract 4 from both sides. The four on the left would cancel out and the 13 on the right would now be a 9. Therefore, the answer is $x \leq 9$
