Answer:</h2>
<h2>
Step-by-step explanation:</h2>
From the given graph, we can know two points:
Using the slope intercept form of the equation of a line, we get:
Where the slope is 
and the y-intercept is 
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:
And the slope intercept form of this equation is:
So the slope is and the y-intercept is 
, the systems formed by these two equations has no solution.
Answer:
810 m
Step-by-step explanation:
Split the polygon into two parts
(Small and Big rectangle)
SR : 18(18+3) = 378
BR : 18(3+3+18) = 432
378+432 = 810
Hope this helps :)
Diameter = 10cm
radius =10/2 = 5 cm
Area = πr² = 3.14 * 5² = 78.5cm²
Answer:
n = 2.5
Step-by-step explanation:
distribute
-20n + 12 + 2.6 + 12n = -5.4
combine terms
-8n + 14.6 = -5.4
subtract 14.6 from both sides
-8n = -20
divide by -8
n = 2.5
