Answer:
6.25 Miles
6 1/4
Step-by-step explanation:
3 + 2 = 5 MILES
1/2 you want the denominator to equal 4 so you times it by two
= 2/4
2/4+3/4= 5/4
this gives you one full mile and 1/4
add all together 5+1+1/4
I am picking this is right :)
Y= -3/5x - 2 Add -3/5x to both sides
3/5x +y= -2 Multiply both sides by 5 because 5 is the denominator.
By multiplying by 5 you can cancel out and make it a real number.
5(3/5x +y) = -2(5)
3x + 5y= -10 is the answer.
The second one
Pls mark brainliest
I really hope this is right but 6?
Answer:
7
Step-by-step explanation:
f(x) = 2x^3 + x^2 − 3x + 1
f'(x) = 6x^2 + 2x − 3
The slope at -2:
f'(-2) = 6(-2)^2 + 2(-2) − 3
f'(-2) = 24 + -4 − 3
f'(-2) = 17
-----
The slope at 0:
f'(0) = 6(0)^2 + 2(0) − 3
f'(0) = − 3
The average rate of change is (17+(-3))/2, or 14/2, or 7
