Answer:
Step-by-step explanation:
Slope is 4/-5
Use the point-slope form of the equation:-
y - y1 = m(x - x1) where m=slope and (x1,y1) is a point on the line
Here we have
y - 5 = -1/2(x - (-5))
y - 5 = -1/2(x + 5)
y = -1/2x - 5/2 + 5
y = -1/2x + 5/2
this can also be written as
2y = -x + 5
or in standard form it is x + 2y = 5
Take the coefficient of x which is 20 and divide divide by two giving you 10 Now square that to get 100.
You would need to add 100 to both sides to complete the square.
Step-by-step explanation:
<span>The square root of -16 is an imaginary number and a complex number. Sqrt(-16)=4i. We use the i to indicate that the number is imaginary since there is no number that can be multiplied by itself to get a negative number (a negative times a negative is a positive, and a positive times a positive is also a positive). So the use of i tells you immediately that it's an imaginary number. You can tell the number is complex because it has both a real and an imaginary part and could be written in the form a+bi, where a is a real number and bi is an imaginary number. In this specific case, the real part (a) is 0 and the imaginary part (bi) is 4i.</span>
