What are the approximate solutions of 4x2 + 3 = −12x to the nearest hundredth?

Gwar [14]

First
$4x^{2} + 12x + 3 = 0$
determine if this equation were factorable, it's not for this one
so I use quadratic formula, try to search the formula online

$x1 = \frac{-12 + \sqrt{(12)^{2} - 4*4*3} } {2*4} = \frac{-12 + 4\sqrt{6} }{8} = \frac{4(-3 + \sqrt{6}) }{8} = \frac{-3 + \sqrt{6}}{2} = - 0.28$
$x2 = \frac{-12 - \sqrt{(12)^{2} - 4*4*3} } {2*4} = \frac{-12 - 4\sqrt{6} }{8} = \frac{4(-3 - \sqrt{6}) }{8} = \frac{-3 - \sqrt{6}}{2} = - 2.72$

<span>x ≈ −2.72 and x ≈ −0.28 is the solution</span>

Please help me with this question

Vikki [24]

Answer:

see below

Step-by-step explanation:

The third table shows a relationship of y=2x.

_____

Essentially, you have to see whether the value of y/x is constant for all the values in a table. If it is not, then the relation is not proportional.

in the first table, -4/-2 ≠ -3/-1

in the second table, -4/-2 ≠ 3/1

in the fourth table, -4/-2 ≠ 6/2

Enter your answer in the box.

TEA [102]

This is an arithmetic series,
so
S(n) = (n/2)*(a(1)+a(n))
S(25) = (25/2)*(a(1)+a(25))
n=25
a(n) = 3n-2
a(1)= 3*1-2=1
a(1)=1
a(25) = 3*25-2=75-2=73
a(25)=73

S(25) = (25/2)*(1+73)=(25/2)*74=925
S(25)=925

Answer : 925
