Answer
Find out how many eighty fours are in 672.
To prove
Let us assume that the number of the 84 be x .
As given in the equation
Total values given in the question be 672.
Than the equation becomes
84 × x = 672
Simplify the above equation
84x = 672
x = 8
Therefore the Numbers of eighty fours in 672 is 8 .
Answer:
<u>Step-by-step explanation:</u>
(1, 2) and (4, -3)
First, find the slope (m):
m =
=
Next, choose ONE of the points and input the point and slope into the Point-Slope formula: y - y₁ = m(x - x₁)
y - 2 = (x - 1)
y - 2 = +
y = +
Then, determine which inequality symbol will result in (-2, 8) being False (since it is not a solution):
y ___ +
8 ___ +
8 ___
8 >
so ≤ makes the statement False
⇒ y ≤ +
****************************************************************
If you need a "system" of inequalities, then you need another equation.
There are infinite possibilities. Graph the points to see what works.
y < 8 or x > -2 are two examples.
---> I just realized that the system can be simpler than what I did above:
