Write the equation of the line<br> perpendicular to y = *x+7 with a<br> y-intercept of (0-1)

I am Lyosha [343]

Answer: y = -x - 1

<u>Step-by-step explanation:</u>

Use the Point-Slope formula: $y - y_1=m_{\perp}(x-x_1)$ where

(x₁ , y₁) is the given point (0, -1)
$m_{\perp}\ \text{is the opposite reciprocal slope of the given line}\implies m_{\perp}=-1$

Insert those values into the formula and solve for y:

y - (-1) = -1(x - 0)

y + 1 = -x

y = -x - 1

Maslowich

Answer:

$log_3(\frac{21}{5}) = log_3(7) - log_3(5)+ 1$

Step-by-step explanation:

Given

$log_3(\frac{21}{5})$

Required

Express in terms of $log_3(5)$ and $log_3(7)$

$log_3(\frac{21}{5})$

Express 21 as 7 * 3

$log_3(\frac{21}{5}) = log_3(\frac{7 * 3}{5})$

Apply law of logarithm

$log_3(\frac{21}{5}) = log_3(7) + log_3(3) - log_3(5)$

$log_3(3) = 1$ . So, we have:

$log_3(\frac{21}{5}) = log_3(7) + 1 - log_3(5)$

Rewrite:

$log_3(\frac{21}{5}) = log_3(7) - log_3(5)+ 1$
