Answer:
y=-3x+6
Step-by-step explanation:
(y2-y1)/(x2-x1)
(0-6) / (2-0)
0-6= -6
2-0= 2
-6/2= -3
slope is -3
so now we have y=-3x+b
in the coordinates (0,6) it means if x is 0 then y is 6. so the y-intercept is 6.
Therefore the equation would be y=-3x+6
However the
are chosen, the sum is equivalent to the definite integral,
which can be computed via integration by parts. If
and
, you have
or equivalently,
The second set of points is your answer.
Answer:
204
Step-by-step explanation:
Plug it into a calculator
or
20 multiplied by -4.25 then subtracted by 16 times -4.25 squared.
Answer:
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one
<em>For the graph below, what should the domain be so that the function is at least 200? graph of y equals minus 2 times the square of x plus 30 times x plus 200
</em>
My answer:
Given the above information, we have:
To make the function is at least 200, it means that:
≥ 200
<=> ≥ 0
<=> x(-2x+30) ≥ 0
This is the product of two numbers hence would be positive only if either both are positive or both are negative
x ≥ 0 and (-2x+30) ≥ 0
<=> 0 ≤ x ≤ 15
Then we get
This is inconsistent as a value cannot be less than 0 and greater than 15
=> our correct answer is
Hope it will find you well.
