Answer:
Step-by-step explanation:
This kinda looks like the limiting definition of a derivative.
Anyway, what we are doing with the f(2 + h) is evaluating f(x) with 2+h in place for x. That looks like this:
f(2 + h) = 2(2 + h) - 3 which simplifies to
f(2 + h) = 4 + 2h - 3 which simplifies to
2h + 1
From that we are subtracting f(2). What we are doing with that is evaluating f(x) with 2 in place for x. That looks like this:
f(2) = 2(2) - 3 which simplifies to
f(2) = 4 - 3 which simplifies to
f(2) = 1. Now put those together over h to get:
Answer choice A so angle A is equivalent to angle D
Answer:
D
Step-by-step explanation:
First, find the slope of BC :
⇒ m (BC) = -1 - 5 / -3 - 5
⇒ m (BC) = -6/-8
⇒ m (BC) = <u>3/4</u>
Now, since AD is the altitude of BC, we can say the altitude is perpendicular to BC.
Hence, the slope of a perpendicular line is equal to the negative reciprocal of the original line.
⇒ m (AD) = - (1/m(BC))
⇒ m (AD) = - (1/(3/4))
⇒ m (AD) = -4/3
Answer:
lets start with the easy equation. X+Y=60. so we take 60 and subtract Y to get X by itself. meaning X = 60-Y. every time we see X replace with (60-Y).
X + 5Y = 100 change to
60-Y+5Y = 100
5Y - Y = 4y.
60+4Y = 100. 100 minus the 60 = 40. 4Y=40. divide by 4. Y = 10. ok so now we solve for X. X + Y (or 10) = 60. 60-10 = 50. X = 50.
Step-by-step explanation:
Replace x and y in the equation with what they tell you x and y equal.
2(14) / 13 - 9(1/3)
Now simplify:
2 x 14 = 28
9 x 1/3 = 3
You now have:
28/13-3
Simplify again to het 28/10 this can be reduced to 14/5
