Step-by-step explanation:
Given
Function;

Find an equation perpendicular to the given function if it passes through (-3,9)
First, we need to determine the slope of:
The slope intercept of an equation is in form;
<em>Where m represent the slope</em>
Comparing 
to ;
We'll have that
Going from there; we need to calculate the slope of the parallel line
The condition for parallel line is;
Substitute
Divide both sides by -2
The point slope form of a line is;
Where 
and
becomes
Open the inner bracket
<em>Hence, the point slope form of the perpendicular line is: </em>

Answer:8 and 12
Step-by-step explanation: 8 is 4 less than 12 and 12 and 8 equals 20
Answer:
-12
Step-by-step explanation:
You can find the value of k(-3) by substituting t = -3 into the absolute value function k(t) = -|4t|.
k(-3) = -|4*-3| = -|-12| = -12
The best thing to do is to find 10%, and you can do this by dividing $270 by 10, and therefore, $27 is equal to 10%.
To find 40%, you've got to multiply $27 by 4, and this gives you $108.
Therefore, gabriel saved $108 last month :)
180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
do you understand how to do it now ?
