Answer:
Step-by-step explanation:
All we are doing here is solving for the b in
, which is the standard form for an exponential function.
Use the first 2 coordinate pairs to solve for b: (1, 6) and (2, 4):
so
and use that when you write the next equation using the next coordinate pair:
which simplifies to
4 = 6b so
, the second choice there. Another way of saying multiplicative rate is the rate of decay or the rate of growth. Same thing. This is decay since 2/3 is greater than 0 but less than 1.
Answer:
8x - 28y
Step-by-step explanation:
-2(-1x + 5y) + 3(2x - 6y)
2x - 10y + 6x - 18y
collect like terms
2x + 6x - 10y - 18y
8x - 28y
'is' in mathematics means equal
'of' in mathematics means multiplication
percent means over 100
84 = 74% * x
84 = 74/100 * x
84 = 37/50 * x
Multiply 50/37 on both sides, so we can isolate 'x'
85 * 50/37 = x
x = 4250/37
x ≈ 114.864865
84 is 74 percent of <span>114.86</span>.
Answer:
<h2>70 ft</h2>
Step-by-step explanation:
120 below we can use a model to figure this out.
sea level is 0
the submarine <u>goes 120 down</u>, so its -120
it <u>goes up by 50</u>, so now its <em>70</em>
no other obstacles, 70 or A is your answer.
