What are the solutions of 4x2 + x = -3? (5 points) and x2 - 7x = -12 (5 points)

Yuki888 [10]

4x^2 + x + 3 = 0

x = [-1 +/- sqrt (1^2 - 4 * 4 * 3)] / 8 = - 1 +/- sqrt ( --47) / 8

= ( - 1 +/- sqrt47i) / 8 = -0.125 + 0.857i , -0.125 - 0.857i

GIVING A BRAINLIST PLZZ ASAP

Answer:

(b) Mr. Sánchez's class earned more money.

(a) $\displaystyle [42, 37] → [j, p]$

Step-by-step explanation:

{79 = p + j

{118,17 = 1,65p + 1,36j

−25⁄34[118,17 = 1,65p + 1,36j]

{79 = p + j

{−86 121⁄136 = −1 29⁄136p - j >> New Equation

__________________________

$\displaystyle \frac{-7\frac{121}{136}}{-\frac{29}{136}} = \frac{-\frac{29}{136}p}{-\frac{29}{136}}$

$\displaystyle 37 = p$ [Plug this back into both equations above to get the j-value of 42]; $\displaystyle 42 = j$

The next step is to plug the solution into the BOTTOM EQUATION to calculate the total money earned for each class:

Sánchez's class

$\displaystyle 61,05 = [37][1,65]$

Altogether, thirty-seven fruit pies cost $61,05.

Kelly's class

$\displaystyle 57,12 = [42][1,36]$

Altogether, forty-two bottles of fruit juice cost $57,12.

* Based on the calculation, it is perfectly clear that Mr. Sánchez's class earned more money by $3,93:

$\displaystyle 3,93 = -57,12 + 61,05$

I am delighted to assist you anytime my friend!
