Step-by-step explanation:
![log \frac{a}{b} = loga - logb](https://tex.z-dn.net/?f=log%20%5Cfrac%7Ba%7D%7Bb%7D%20%20%3D%20loga%20-%20logb)
logx - log3 = log(x-2)
![log( \frac{x}{3} ) = log(x - 2)](https://tex.z-dn.net/?f=%20%20log%28%20%5Cfrac%7Bx%7D%7B3%7D%20%29%20%3D%20log%28x%20-%202%29)
![\frac{x}{3} = x - 2](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3%7D%20%20%3D%20x%20-%202)
x = 3(x - 2)
x = .......
Answer:
3. Yes, because it can be written as 23/100
Step-by-step explanation:
answer:
$0.75
Step-by-step explanation:
the function can be represented as:
f(x)=0.25x+3.5
the function produces the following values for years 1, 2, and 3 respectively:
f(1)=0.25(1)+3.5=3.75
f(2)=0.25(2)+3.5=4.00
f(3)=0.25(3)+3.5=4.25
therefore,
there is a $0.75 increase per year
A=andy's age
b=belinda's age
3a=11+2b
a+b=-2+2b
wowie
a+b=-2+2b
minus b from both sides
a=b-2
subsitute b-2 for a
3a=11+2b
3(b-2)=11+2b
3b-6=11+2b
minus 2b from both sides
b-6=11
add 6 to both sides
b=17
subsitute
a=b-2
a=17-2
a=15
andy is 15
belinda is 17
Perimeter = 2 x length + 2 x width
Perimeter = 2 x 10 + 2 x 4 = 20 + 8 = 28 cm
Area = length x width
Area = 10 x 4 = 40 square cm
