What is the equation, in slope-intercept form, for the line through the point

Mathematics

goblinko [34]2 years ago

Answer:

A perpendicular line has an opposite-reciprocal slope.

The slope given is m = 5. So the perpendicular slope is m = -\frac{1}{5}.

Now subsitute your (x, y) values to find the y-intercept, b.

y = -\frac{1}{5} x + b

-1 = -\frac{1}{5}( 3) + b

-1 = -\frac{3}{5}+ b

-1 + \frac{3}{5} = b

-\frac{5}{5} + \frac{3}{5} = b = -\frac{2}{5}

Answer: y = -\frac{1}{5} x - \frac{2}{5}

Step-by-step explanation:

1. 5 less than one fourth of x is y.
horsena [70]

Answer

y = (1/4)x - 5                 or     4y - x + 20 = 0

Explanation

To get the rule required, we interpret the sentence and write it in a mathematical form.

5 less than one fourth of x is y  

one fourth of x ⇒ (1/4)x

5 less than one fourth of x is y  ⇒  (1/4)x - 5 = y

y = (1/4)x - 5

4y = x - 20

4y - x + 20 = 0

Hey! I would appreciate some help with this
arsen [322]

Answer:

...

Step-by-step explanation:

since they give us the side opposite of the given angle(Opposite) and we are trying to find for a (Adjacent/side), so we use TOA

tan(30)= \frac{4}{a}

i see u dont want it solved but ill solve it anyways

since a is on the bottom then lets switch them

x=\frac{4}{tan30}

x= 6.928

The Smith family went to eat at Buffalo Wild Wings. The bill was $43.86. They gave the server a 20% tip. How much did they pay a
Marysya12 [62]
<h2>Answer:</h2>

$52.63

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

To find 20% of $43.86 we multiply $43.86 by 0.2

$43.86 • 0.2 = $8.772

Now add $43.86 and $8.772 to find out how much the family paid altogether.

$43.86 + $8.772 = $52.632

In money the smallest place value is cents so we have to round to the hundredths place.

Doing this we get the grand answer of:

$52.63
