Answer: The correct option is second.
Explanation:
The given function is,
If we graph a function is f(x), then its coordinates is defined as (x,f(x)).
When the graph of f(x) is reflect across the x-axis, then the the x-coordinate remains the same and the sign of y-coordinate is changed. It means after reflecting across the x-axis,
The given given equation can be written as,
To find the equation of the graph after reflection across the x-axis multiply both sides by -1.
Because f(x)=y and g(x)=-y.
Therefore the second option is correct and the graph of both function is given below.
Answer- 85,7 g
300:7= 42,85
42,85x2=85,7
Answer:
$3100
Step-by-step explanation:
Step one:
given data
Principal = $2500
rate = 1.2%
time = 20 years
Step two:
The simple interest is expressed as
SI= PRT/100
substitute
SI= 2500*1.2*20/100
SI= $600
The account balance after 20 years is
= principal + Simple interest
= 2500+600
= $3100

if one day drops 1,2
one week 7 day drops 7×1,2=8,4
two week 14=2×7 day 2×8,4=16,8
Step-by-step explanation:
Let x be the number of Green apples bought.
Then 4x is the number of Red apples bought.
We have x + 4x = 50, so x = 10.
Since there are 10 green and 40 red apples, 40 - 10 = 30 more red apples than green apples.
