Answer:
-3x + 14
Step-by-step explanation:
Expand -3(x-5)
. -3 * x = -3x
. -3 * -5 = 15
So
. y+1 = -3x + 15
Subtract 1 from both sides so that y is the subject
. y = -3x + 14
Now you can juse replace y with f(x) since theyre basically the same thing
Step-by-step explanation:
so whats the equation
<em> The radius of a circle is 10 m. Find its area to the nearest whole number.</em>
<em />
<em />
We're asked to find the area of the circle, which we can find using the following formula:-
Where:-
- π = pi [3.14...]
- r=radius (10 m)
<h3>What we need to do to find the area:-</h3>
Substitute 10 for r and 3.14 for π:-
On simplification,
On further simplification,
The Area is:-
Note:- Area is always measured in units² (units squared)
<h3>Good luck with your studies.</h3>
