Order the steps to solve the equation

Mathematics
1 answer:
nalin [4]2 years ago
5 0

The order of steps to solve the equation are;

x^2 − 15 = 2x

(x − 5)(x + 3) = 0

x − 5 = 0 or x + 3 = 0

Potential solutions are −3 and 5

<h3>Logarithm functions</h3>

Logarithm expressions are inverse of an exponential function. Given the logarithm expression shown below:

log(x^2 − 15) = log(2x)

Cancel the log on both sides

x^2-15 = 2x

Equate to zero

x^2-2x-15 = 0

Factorize

x^2 -5x + 3x -15 = 0

x(x-5)+3(x-5) = 0

(x-5)(x+3) = 0

Find the solution

x - 5 = 0 or x + 3 = 0

Potential solution are 5 and -3

In an interview for a secretary position at the dealer, a typist claims a tying speed of 45 words per minute. On
MAXImum [283]

Using the hypothesis test for one sample mean, There is NO SIGNIFICANT EVIDENCE to support the typist's claim

H_{0} = 45\\H_{1} < 45\\\\

The test statistic :

T = (x - μ) ÷ (s/√(n))

T = (43 - 45) ÷ (15/√70)

T = - 2 ÷ 1.7928429

T = -1.1155

At α = 0.05

Pvalue :

Degree of freedom, df = 70 - 1 = 69

Pvalue = 0.134

Decison region :

Reject H_{0} if Pvalue < α

Since Pvalue > α We fail to reject the Null

Solve: + 12x = 9<br> Ox=3/5 :: 6<br> O x= 6 745<br> O=-6+ 745<br> O *=-6_315
Alex_Xolod [135]

Answer:

x =  \frac{3}{4}

Step-by-step explanation:

12x = 9

Divide both sides by 12:

\frac{12x}{12}  =  \frac{9}{12}

Simplify the fraction:

x =  \frac{9}{12}

Find the greatest common factor of the numerator and denominator:

x =  \frac{3.3}{4.3}

Factor out and cancel the greatest common factor:

x =  \frac{3}{4}
