The answer would be the second one because of the 45-45-90 Right Triangle rule. If the side lengths are the same the the hypotenuse is just the square root of that number.
Answer:
A. 4-x
Step-by-step explanation:
2x-8+3(4-x)
multiply 3(4-x)
2x-8+ 12- 3x
add -8 and 12
add 2x and -3x
4-x
i believe that A. 4-x is correct.
Answer:
- f = -2/5a +14
- 12.4 ≈ 12 fish for 4 algae blooms
Step-by-step explanation:
The 2-point form of the equation for a line is useful when you are given two points to work with:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
The independent variable (x) is apparently "algae blooms" and is to be represented by "a". The dependent variable (y) is "number of fish" and is to be represented by "f". So, we have ...
f = (4 -10)/(25 -10)(a -10) +10
f = -6/15(a -10) +10
f = -2/5a +14 . . . an equation for the scenario
Four a=4, the fish population is predicted to be ...
f = -2/5(4) +14 = 12.4
There will be about 12 fish when there are 4 algae blooms.
Please finish the rest of the question.
