Answer:
The answer is c: -42
Step-by-step explanation:
Because f(8): 6(1-8) is 6(-7) so is -42.
4x + 3 = -5x - 7 Add 5x to both sides.
4x + 3 + 5x = -5x - 7 + 5x
9x + 3 = -7 Subtract 3 from both sides.
9x + 3 - 3 = -7 - 3
9x = -10 Divide both sides by 9
9x / 9 = -10 / 9
Your answer can either be 1.11111... or it would be x = -10/9
Answer:

Step-by-step explanation:
The story tells us that Boa drove from the Dead Sea up to Jerusalem. With the data provided, we can assume a linear relationship between altitude and the number of hours. We are given two key data: one point and the rate of change (or slope).
We can easily find the equation of a line with slope m passing through a point (a,b) by using the formula

In this case, y is the altitude above sea level, and x is the number of hours of driving
The value of m is 740 meters/hour and the known point is x=1.5 hours, y=710 meters. Using these values



Answer:
If y = sin(4x)
y' = 4cos(4x)
Step-by-step explanation:
lim [ f'(x) = f(x+h) - f(x) / h ]
h → 0
sin'(x) = sin(x+ε) - sin(x) / ε
