Answer:
28 fish
Step-by-step explanation:
The density here is written as fish over feet cubed, so this equation can be written as 0.4=x fish/70 cubic feet
To get x alone you must multiply 0.4 by 70 to get 28, which represents the number of fish
Mary has 32
John has X
Jerry has 95
X=1/3 x 95
X= 31.6666667
X is 31 apples because you can’t have .66~ of an apple!

Answer:
Undefined.
Step-by-step explanation:
The line given on the graph is vertical.
All vertical lines have an undefined slope.
This is because that it has no horizontal (run) change.
If you used the slope formula for the points, the denominator of the fraction will be a zero, and and you cannot divide by zero.
Hope this helps!

Answer:
Step-by-step explanation:
f(x) is like y in a linear equation. There is one major difference. F(x) tells you what to substitute on the right every time you see an x.
f(a) = -3a + 7
f(b) = -3b + 7
For this question a and b have values. Now work with the right side only. This is the quickest way to get the answer, but it is only marginally correct.
f(a) = -3(-8) + 7 = 24 + 7 = 31
f(b) = -3(7) + 7 = -21 + 7 = - 14
f(a) + f(b) = 31 - 14 = 17
f(a) - f(b) = 31 - (-14) = 31 + 14 = 45
