Can you solve this for me please in a good way

Answer:

x = -2

Step-by-step explanation:

If you factor out 1/9 you get rid of the fractions and that makes the equation a whole lot easier.

(5x+10)^2 - x(25x+27) + 46 = 0

Next, eliminate the brackets:

25x^2 +100x + 100 - 25x^2 - 27x + 46 = 0

Combine the terms:

x = \frac{- 146}{73} = -2

4^x+2=1/2 solve for x (log equation)
lesantik [10]

\log_ab=c\iff a^c=b\\\\4^{x+2}=\dfrac{1}{2}\qquad\text{use}\ a^{-1}=\dfrac{1}{a}\\\\(2^2)^{x+2}=2^{-1}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2(x+2)}=2^{-1}\iff2(x+2)=-1\qquad\text{use distributive property}\\\\(2)(x)+(2)(2)=-1\\\\2x+4=-1\qquad\text{subtract 4 from both sides}\\\\2x=-3\qquad\text{divide both sides by 2}\\\\\boxed{x=-1.5}

Write an equation in slope intercept form of the line with the given characteristics:
stiks02 [169]

Answer:

The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7

Step-by-step explanation:

The slope-intercept form of an equation is given by:

y = mx+b

here m is the slope of the line and b is the y-intercept

Given

m = 2

Putting m=2 in the general form

y = 2x+b

In order to find the y-intercept, the given point (-3,1) will be substituted in the equation

So

1 = 2(-3)+b\\1 = -6+b\\b = 1+6\\b = 7

Putting the value of b

y = 2x+7

Hence,

The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
