answer:
-2x + 9 or -2 which is what the question asks
step-by-step explanation:
- we have to combine like terms which means terms that are similar
- in this, only 5x and -7x are like terms since both have x with them
- 9 will stay the same since it does not have a like term
5x + 9 + (-7x) = __x + 9
-2x + 9
- therefore, -2 goes in the blank
Answer: There are 16 fish that he can keep in the aquarium.
Step-by-step explanation:
Since we have given that
Length of aquarium = 4 feet
Width of aquarium = 1 foot
So, it forms a shape of cuboid.
As we know the formula for "Volume of Cuboid":
![Volume=Length\times Breadth\times Height\\\\Volume=4\times 1\times 2\\\\Volume=8\ ft^3](https://tex.z-dn.net/?f=Volume%3DLength%5Ctimes%20Breadth%5Ctimes%20Height%5C%5C%5C%5CVolume%3D4%5Ctimes%201%5Ctimes%202%5C%5C%5C%5CVolume%3D8%5C%20ft%5E3)
According to question, Each fish needs atleast 0.5 cubic feet of water.
So, Number of fish that he can keep in the aquarium is given by
![\frac{8}{0.5}=16](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B0.5%7D%3D16)
Hence, there are 16 fish that he can keep in the aquarium.
We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
Answer:
-14
Step-by-step explanation:
step 1:
Subtract 11 from both sides.
y+11−11<−3−11
y<−14
