Answer:
Malik substituted 60 for y instead of x
Step-by-step explanation:
<u><em>The complete question is</em></u>
Malik’s solution to the equation ,2/5x-4y=10 when x=60, is shown below.what error did Malik make first when solving the equation ?
Options are
malik did not multiply correctly. malik added 240 to each side of the equation. malik did not multiply correctly. malik substituted 60 for y instead of x
<u>Malik’s solution is</u>
we have
For x=60
substitute the value of x in the equation and solve for y
therefore
Malik substituted 60 for y instead of x

I think the answer is C not to sure
One way to solve this would be to graph both y=x^2+6x+18 and y=2 - 1/x. If the graph of the polynomial is always higher up (above) the graph of y=2-1/x, that alone is sufficient cause to state that the poly is always greater than 2-1/x.
You could also do this algebraically: write the inequality
x^2+6x+18 > 2 -1/x. This can be rewritten as x^2+6x+18-2+1/x > 0, or
x^2+6x+16+1/x > 0
Try x=-3. Then 9-18+16-1/3 = 6 2/3, which is greater than 0.
Or you could graph x^2+6x+16+1/x by hand or on a calculator. Is the graph always above the x-axis? If so, <span>x²+6x+18 is always greater than 2-1/x.
