Decomposers break down things that aren't usable anymore or that die and recycle it back into the environment to use in other processes.
(40 mile / hr) x (5280 feet / 1 mile) x (1 hr / 3600 s) = 58.67 ft / s
The Jackrabbits' speed may also be expressed as 58.67 ft / s.
Answer:
x=1, y=-7
Step-by-step explanation:
y=-9x+2 -->y+9x=2
y=-3x-4 -->y+3x=-4
subtract the equations
6x=6
x=1
substitute
y=-9+2
y=-7
In order to answer, you need to sketch the given exponential curves and straight lines and ask yourself if and when do they cross each other:
a) 2ˣ + 1 is an esponential curve with base >1 shifted up by 1;
-3x + 6 is a straight line with negative slope, shifted up by 6;
They cross each others only one time.
b) 3ˣ - 3 is <span>an esponential curve with base >1 shifted down by three, thus it can be negative;
2x - 2 is </span><span> a straight line with positive slope shifted down by 2;
They cross each others twice.
c) -4</span>ˣ - 1 is <span>an esponential curve with base >1 flipped over the x axis and shifted down by 1;
3</span>⁻ˣ - 2 is an esponential curve with base <1 ( 3⁻ˣ = (1/3)ˣ )and shifted down by 2;
They never cross each others.
Therefore the correct rder is:
-4ˣ - 1 = 3⁻<span>ˣ - 2
</span>-3x + 6 = 2<span>ˣ + 1
</span>3<span>ˣ - 3 = 2x - 2</span>
Answer:
5x+10
Step-by-step explanation:
(7x+4) - (2x-6)
Distribute:
7x + 4 - 2x + 6
Combine like terms
5x + 10 (ans)
