Select the equation of the line that passes through the point (5,7) And is perpendicular to the line X equals four

1 answer:

8 0

X = 4 is a vertical line and only a horizontal line can be perpendicular to it.
Horizontal lines equations are of the form y = #
and if it passes through the point (5, 7), then y = 7 is the answer.

The functions q and r are defined as follows

kolezko [41]

Answer:

Step-by-step explanation:

So we have the two functions:

$g(x)=-2x-2\text{ and } r(x)=x^2-2$

And we want to find the value of r(g(4)).

To do so, first find the value of g(4):

$g(x)=-2x-2\\g(4)=-2(4)-2\\$

Multiply:

$g(4)=(-8)-2$

Subtract:

$g(4)=-10$

Now, substitute this into r(g(4)):

$r(g(4))\\=r(-10)$

And substitute this value into r(x):

$r(-10)=(-10)^2-2$

Square:

$r(-10)=100-2$

Subtract:

$r(-10)=98$

Therefore:

$r(-10)=r(g(4))=98$

Lenny bought a motorcycle. he paid 12.5% in tax. the tax added $1437.50 to the price of the motorcycle. what was the price of th

Lyrx [107]

<span><span>In order to calculate the initial price of the motorcycle, we use the formula:
Total item price=(Item price*tax rate)+item price.
Rearranging the equation to solve for the unknown:
Item price=total item price/Tax rate.
Substituting the real values into the formula:
Item cost=1,437/12.5%. The result of this equation determines that the original price of the motorcycle (not including tax) is:
$11,496-$1,437=$10,059</span></span>
