Answer:
y = - x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 2) ← 2 points on the line
m = = -
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y = - x + 4 ← equation of line
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.
Answer:
-74
Step-by-step explanation:
7). It is not possible. It is impossible.
An "acute" triangle is a triangle in which all three angles are acute.
"Acute" means "less than 90 degrees".
A "right triangle" has a 90-degree angle in it, so all three
of its angles can't possibly be acute.
8). Yes, Karen speaks the truth.
In an equilateral triangle, all three angles have
the same size, namely 60 degrees.
Studying this number astutely, you will notice that
it is less than 90 degrees.
Therefore, all three angles in an equilateral triangle are acute angles.
Therefore, every equilateral triangle is a cute one.
9). An equilateral triangle is one with all three sides the same length.
An isosceles triangle is one with two sides the same length.
A scalene triangle is one with all three sides different lengths.
You can drawum.
