Answer:
(a) f(7) = 23
(b) x = 13/3
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
(a) f(7) is x = 7
(b) f(x) = 15
Step 2: Substitute and Evaluate
(a) f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
(b) 15 = 3x + 2
13 = 3x
x = 13/3
Hope i understand it right
2sqrt2 +3 is area of a square so this mean that side *side = 2sqrt2 +3
so s^2 = 2sqrt2 +3
s = sqrt(2sqrt2 +3)
hope this will help you
Answer:
x= -4/11
Step-by-step explanation:
first add 7x to both sides of the equation leaving you with 4.4x + 7.6 = 6
then subtract 7.6 from both sides which gets you 4.4x = -1.6
divide both sides by 4.4 and simplify
x= -4/11
Answer:
3,240
Step-by-step explanation:
The computation of the population of rabbits in the year 2003 is shown below:
Given that
In the year 1995, the population of the rabbits was 1000
And, in 1999 the population of the rabbits grown to 1,800
So there is an increase of
= (1800 - 1000) ÷ 1000
= 80%
So for 2003, the population of the rabbits is
= 1800 + (1800 × 0.80)
= 3,240
