Slope of the function is 5000. It seems the question is in the video so rewatch to find what it is representing.
The answer is 12cm2
The formula for getting 12cm2
Count the square beneath the base and the length
base=4
length=6
1/2x6x4=12cm2
Answer:
The last two terms of the expression are

Both the last terms has variable of degree equal to (2+4=6) and (3+3=6).So, the first term must have degree greater than 6.
Correct Options are

Answer:
30% discount
Step-by-step explanation:
To find the percent discount write a proportion.

Cross multiply numerator with denominator of each fraction to solve for x.
1344(100) = 1920(x)
134400 = 1920x
70 = x
This means you pay 70% of the price. The discount was 30%.
Solve the equation for both -1 and 1 first.
50(1/2)^-1 = 100
50(1/2)^1 = 25
Now subtract the two answers and divide by 2 ( -1 to 1 is 2)
75/2 = 37.5
Because the answer got smaller from -1 to 1, the change would be negative.
The rate of change would be -37.5
