F(x) = 3x+1
put x = a+h
f(a+h) = 3(a+h) + 1
f(a+h) = 3a + 3h + 1
put x = a
f(a) = 3a + 1
f(a+h)-f(a) = 3a + 3h + 1 -(3a+1)
f(a+h)-f(a) = 3a +3h + 1 - 3a -1
f(a+h)-f(a) = 3h
Answer:
$70
Step-by-step explanation:
If the account start with $95, and you deposited $15:
95+15 = $110
After that, you took 65:
110 -65 = $45
After you deposited $40:
45 + 40 = $85
And for last you took more 15:
85 -15 = $70
Answer:
450 cm
Step-by-step explanation:
12 degrees is 1/30 of the circumference because there are 360 degrees in a circle.
The minor arc length of 15 is in the same ratio to the circumference as the 2 angles , so the circumference = 30 * 15 - 450 cm.
Answer:
45 i think i dont know
Step-by-step explanation:
m
∠

holds true.
Complementary angles have a sum of
90
˚
. Thus, if
∠

and
∠
