f(x) = x^2 -3x +2
Replace x with 2:
f(2) = x^2 -3(2) +2
f(2) = 4-6 +2
f(2) = 0
g(x) = 4x-5
replace x with -1
g(-1) = 4(-1) -5
g(-1) = -4-5
g(-1) = -9
Now subtract
f(2) - g(-1) = 0 - (-9) = 0+9 = 9
The answer is 9.
The answer would be 2 and 3/10. To find this, I multiplied 1 and 1/2 by 2 and 3 and 1/2 by two. So, now to make 3 dozen muffins, a recipe uses 7 cups of flour. I did this because obviously dividing 3 and 7 are easier and its hard to find how many cups of flour make 1 dozen when you have the equation for 1 and 1/2 because 1 doesn't go into 1 and 1/2 equally. Now, with the new equation, I can just divide 3 by 3 to get 1 (which would be 1 dozen muffins) and also divide 7 by 3 to get 2.3. 2 is obviously the whole number in the mixed number and .3 is the fraction, which is 3/10. Hope this helps!
Answer:
20
Step-by-step explanation:
Formula
V = B * h
Givens
B = 200.96 square inches
V = 4019.2 cubic inches
Solution
4019.2 = 200.96 * h Divide by 200.96
4019.2/200.96 = h
h = 20 inches
The average speed is obtained by finding the slope of the function in the given interval:
Substituting values we have:
Rewriting:
Then, the generic equation of the line is:
Where,
v: average speed (slope of the line)
(t0, n0): ordered pair that belongs to the line.
Substituting values we have:
Answer:
the average speed of the car is:
b. 0.75
an equation of the line is:
b. n-6= 0.75(t-8)
