Help me fjfjsncjdhdhfh

Deffense [45]

Step-by-step explanation:

$=> 2 {x}^{2} + \frac{7}{2}x + \frac{3}{4} = 0$

$=> \frac{8 {x}^{2} + 14x + 3}{4} = 0$

$=> 8 {x}^{2} + 14x + 3 = 0$

$=> 8 {x}^{2} + 12x + 2x + 3 = 0$

$=> 4x(2x + 3) + 1(2x + 3) = 0$

$= > (2x + 3)(4x + 1) = 0$

$= > x = - \frac{3}{2} or \frac{ - 1}{4}$

Please answer this with the steps included please y-10 = -5/4x + 30/4 for middle school

Phantasy [73]

y-10 = -5/4x + 30/4 represents a linear function; we know that because both x and y have the power 1.

We could put this equation into one of several forms.

Suppose we wanted to put it into slope-intercept form. Then y-10 = -5/4x + 30/4 becomes y = 10 + 30/4 - (5/4)x, or y = 35/2 - (5/4)x. Thus, this line has the slope -5/4 and the y-intercept (0, 35/2).

If this isn't quite what you wanted, then please share the instructions.
