Answer:

Sometimes

Step-by-step explanation:

Similarity means they have the same proportions and that you can dialate a triangle and get the other one. They're both the same shape but not the same size. Sorry I kind of mess up when I explain stuff.

Ainat [17]

So basically they want you to find out how much Kira/employer has to pay per year so

665=monthly
12 months in a year
665 times 12=7980

also the additonal 75 to start so
7980+75=8055 per year or annualy

Graph the equation below by plotting the y-intercept and a second point on the line. When you click Done, your line will appear

Gala2k [10]

Answer:

Step-by-step explanation:

Equation of the line has been given as,

$y=\frac{3}{2}x-5$

By comparing this equation with the y-intercept form of the equation,

y = mx + b

Slope of the line 'm' = $\frac{3}{2}$

and y-intercept 'b' = -5

Table for the points to be plotted on a graph will be,

x y

-4 -11

-2 -6

0 -5

2 -4

4 -3

By plotting y-intercept (0, -5) and any one of the points given in the table we can get the required line.

Write the equation of the line passing through the points (-7,9) and (7,5).

inn [45]

Answer:

$y=-\frac{2}{7} x+7$

Step-by-step explanation:

First Solve For The Slope Using The Two Given Points!

M = Slope

M = $\frac{y2-y1}{x2-x1}$

M = $\frac{5-9}{7--7}$ Two negative signs together makes addition!

M = $\frac{-4}{14}$ Move the negative sign (only if the fraction has a negative)

M = $-\frac{4}{14}$ Simplify

M = $-\frac{2}{7}$ Final Answer

Then see how many units the graph goes up = y-intercept

Which expression is equivalent to log Subscript w Baseline StartFraction (x squared minus 6) Superscript 4 Baseline Over RootInd

zysi [14]

Option b: $4 \log _{w}\left(x^{2}-6\right)-\frac{1}{3} \log _{w}({x^{2}+8})$ is the correct answer.

Explanation:

The expression is $\log _{w}\left(\frac{\left(x^{2}-6\right)^{4}}{\sqrt[3]{x^{2}+8}}\right)$

Applying log rule, $\log _{c}\left(\frac{a}{b}\right)=\log _{c}(a)-\log _{c}(b)$ , we get,

$\log _{w}\left(\left(x^{2}-6\right)^{4}\right)-\log _{w}(\sqrt[3]{x^{2}+8})$

Again applying the log rule, $\log _{a}\left(x^{b}\right)=b\cdot\log _{a}(x)$ , we get,

$4 \log _{w}\left(x^{2}-6\right)-\log _{w}(\sqrt[3]{x^{2}+8})$

The cube root can be written as,

$4 \log _{w}\left(x^{2}-6\right)-\log _{w}({x^{2}+8})^{\frac{1}{3} }$

Applying the log rule, $\log _{a}\left(x^{b}\right)=b\cdot\log _{a}(x)$ , we have,

$4 \log _{w}\left(x^{2}-6\right)-\frac{1}{3} \log _{w}({x^{2}+8})$

Thus, the expression which is equivalent to $\log _{w}\left(\frac{\left(x^{2}-6\right)^{4}}{\sqrt[3]{x^{2}+8}}\right)$ is $4 \log _{w}\left(x^{2}-6\right)-\frac{1}{3} \log _{w}({x^{2}+8})$

Hence, Option b is the correct answer.
