The numbers are "x" and "y".
We can suggest this equation:
x+y=56
xy=72
We can solve this equation by substitution method.
x+y=56 ⇒x=56-y
(56-y)y=72
56y-y²=72
y²-56y+72=0
Now, we solve this square equatión:
y=[56⁺₋√(56²-4*1*72)] / 2=(56⁺₋√2848)/2
We have two solutions:
y₁=(56-√2848)/2≈1.3167 ⇒x₁=56-y₁≈54.6833
y₂=(56+√2848)/2≈54,6833 ⇒x₂=56-y₂≈1.3167
Therefore the numbers are 1.3167 and 54.6833
18x-2-4x=6x-12-2
14x-2=6x-14
8x-2=-14
8x=-12
x=-12/8=-3/2
Answer:
Two points on the line and a point on the line and the slope are known
Step-by-step explanation:
This arises because 2 points can be used to get the slope of the line. You can then use that slope to get the intercept for the line and obtain the entire equation.
