34. For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.

skad [1K]

Answer:

The linear equation for the line which passes through the points given as (-1,4) and (5,2), is written in the point-slope form as $y=\frac{1}{3} x-\frac{13}{3}$ .

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (-1,4) and (5,2).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 3

Determine the slope of the line.

The points through which the line passes are given as (-1,4) and (5,2). Next, the formula for the slope is given as,

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute 2&4 for $y_{2}$ and $y_{1}$ respectively, and $5 \&-1$ for $x_{2}$ and $x_{1}$ respectively in the above formula. Then simplify to get the slope as follows,

$m=\frac{2-4}{5-(-1)}$\\ $m=\frac{-2}{6}$\\ $m=-\frac{1}{3}$$

Step 2 of 3

Write the linear equation in point-slope form.

A linear equation in point slope form is given as,

$y-y_{1}=m\left(x-x_{1}\right)$

Substitute $-\frac{1}{3}$ for m,-1 for $x_{1}$ , and 4 for $y_{1}$ in the above equation and simplify using the distributive property as follows,

$y-4=-\frac{1}{3}(x-(-1))$\\ $y-4=-\frac{1}{3}(x+1)$\\ $y-4=-\frac{1}{3} x-\frac{1}{3}$$

Step 3 of 3

Simplify the equation further.

Add 4 on each side of the equation $y-4=\frac{1}{3} x-\frac{1}{3}$ , and simplify as follows,

$y-4+4=\frac{1}{3} x-\frac{1}{3}+4$\\ $y=\frac{1}{3} x-\frac{1+12}{3}$\\ $y=\frac{1}{3} x-\frac{13}{3}$$

This is the required linear equation.

1/4•9 solve using fractions

bonufazy [111]

Simple,

use 1/4 and 9 has a 1 over it.

Thus,

1/4*9/1= 9/4

In mixed number form it's 2 1/4.

Factor out the coefficient of the variable 1/4d-3/4

maria [59]

The variable is d, so the coefficient is 1/4. Factor out 1/4 and you are left with (d-3).

What is the domain of y=log_5x

Marrrta [24]

<h2>Answer:</h2>

$(0. \infty)$

<h2>Step-by-step explanation:</h2>

Since this is a logarithmic function, the domain is $(0. \infty)$ . But what is the domain of a function? The domain of a function is the set of inputs. This is so, because for any logarithmic function $y=log_{a}(x)$ , x must be greater than 0. So this function is continuous and has an x-intercept at $(1,0)$ , and y increases as x increases. Finally, its graph is shown below.
