No, she did not substitute the correct x and y values :)
In math, Exponentiation refers to the operation of raising one quantity to the power of another. See the program running the exponentiation below.
<h3>What is the required code?</h3>
The code is given below:
number_of_days = 30
amount_after_30days = 0.01 * (2 ** number_of_days)
# print the amount
print(amount_after_30days)

The given are:
cost for each blog = $20
cost for each feature article = $60
blog = 10+2(number of articles sold)
total earnings = $700
where,
a = article
b = blog
to solve,
60(a)+20(10+2a)=700
60a+200+40a=700
200+100a=700
100a=700-200
100a=500
a=500/100
a=5
The total feature articles produced last week was 5.
to check,
a+b=700
60(5)+20[10+2(5)]=700
300+20(10+10)=700
300+200+200=700
700=700
Indeed, the number of articles produced last week was 5.
Answer:
(-4,-4)
Step-by-step explanation:
Since this is centered at (0,0), we have to multiply the x and the y coordinates by the scale factor.
-8 × 1/2 = -4
