Answer:
Step-by-step explanation:
sales earning commission=130,000-21000=109,000
sales commission=5800-900=4900
rate of commission=4900/109,000 ×100=490/109 %
≈4.495
≈4.50%
Answer:
(22, 23)
Step-by-step explanation:
x + ( x + 1) = 45
2x + 1 = 45
2x = 45 - 1
2x = 44
x = 44 ÷ 2
x = 22

Hello :
<span>an equation of the circle Center at the
w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
In this exercice : (x-3)²+y²=7² ....a =3 and b=0 ( the center is :w(3,0)) ... r=7
The distance between each point in each case is calculated and compared with the length of the radius
1 ) </span>A (-1, 1) : Aw² = (-1-3)²+1² =17..... Aw < r : <span>interior the circle
</span> 2 ) B(10, 0) :Bw² =(10-3)²+0² =49 ......r = Bw :<span>circumference of the circle
</span> 3 ) C(4, -8) :Cw² = (4-3)²+(-8)² =65..... Cw > r : exterior the circle
Answer:
-6x+10x^2
Step-by-step explanation:
you just have to distribute the -2x to the numbers inside the parenthesis.
hope this helps
Remember the quotient rule

k, so
top is 3x^2-8x+4, the deritivive of that is 6x-8
bottom is 7x^2+6x+9, deritivive is 14x+6
so

if we simplify it we get

subsituting x=4
