Answer:
-8m + (-7.7n - 6)
Step-by-step explanation:
You distribute the negative in front of the parentheses, to everything inside of the parentheses, and change the sign to addition.
Answer:
18,500 because youvadd 500
Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
The equation of the tangent to the curve at the point P(2, -10) is:
y = 8x - 26



We need to find the coordinates of point Q where the slope of the tangent to the curve f(x) must also be 8.

Now we have a quadratic:

which simplifies to:

which factorizes to:(x + 4)(x - 2) = 0
Therefore x = -4, 2.
f(-4) = 48
Therefore the coordinates of Q are (-4, 48).
