Solve following | 2x + 9 = 15

vivado [14]

Answer:

x₁ = 3

x₂ = - 12

Step-by-step explanation:

Hi there !

| 2x + 9 | = 15

1.

2x + 9 = 15

2x = 15 - 9

2x = 6

x = 6 : 2

x₁ = 3

2.

2x + 9 = - 15

2x = - 15 - 9

2x = - 24

x = - 24 : 2

x₂ = - 12

Good luck !

An artist wants to reduce the size of a drawing using a scale factor of 3:1 . The original drawing has an area of 720 square inc

leonid [27]

Ratio is 3:1 and the original area is 720. So 3/1 is equivalent to 720/x . X is the missing number. Set up like
3/1=720/x
Cross multiply you get 3x=720
Solve for x which is 720/3
New area is 240 square inches

$\begin{array}{llll} \textit{Logarithm of exponentials} \\\\ \log_a\left( x^b \right)\implies b\cdot \log_a(x) \end{array} \\\\\\ \textit{Logarithm Change of Base Rule} \\\\ \log_a b\implies \cfrac{\log_c b}{\log_c a}\qquad \qquad c= \begin{array}{llll} \textit{common base for }\\ \textit{numerator and}\\ denominator \end{array} \\\\[-0.35em] ~\dotfill$

$6\log_6(15)\implies \log_6(15^6)\implies \stackrel{\textit{change of base rule}}{\cfrac{\log_{10}(15^6)}{\log_{10}(6)}}\qquad \approx \qquad 9.068\qquad \approx\qquad 9$
