Answer:
By definition, the derivative of f(x) is
Let's use the definition for
Then,
Answer: Y=mx+b
B is the y intercept and the slope is M
So the answer is Y= -4x+ 0
Step-by-step explanation:
Let the number of $1.5 and $2.5 be x. The number of $4 was (x+0.5x)=1.5x and that of $3 was (x+0.5x+1)=(1.5x+1)
thus the total amount will be:
1.5x+2.5x+4(1.5x)+3(1.5x+1)=78
1.5x+2.5x+6x+4.5x+3=78
14.5x=78-3
14.5x=75
x~5
thus:
The number of :
$1.5 was 5
$2.5 was 5
$3 was 1.5*5+1=7.5=8.5
$4 was 1.5*5=4.5
193.5m is the area because you have to isolate the different shapes in the overall figure, and find the area of those first, once you have found them all you need to add them together
