<h2>Good morning,</h2>

<em><u>Answer</u></em>:

The quadratic equation is :  x²+x+1=0

<u><em>Step-by-step explanation:</em></u>

Generally:

let S be the sum of the roots z₁ and z₂

and P be the product of the roots z₁ and z₂

then z₁ and z₂ are the solutions for the equation:  x² − Sx + P = 0

Now,

S=-1 and P=1 then the equation is x²+x+1=0.

So the slope of the first line is 4/3. If this line is perpendicular, then you have to flip it and switch the sign (flip it n switch it (how I remember it)). So the slope of the new line is -3/4.
Then you have to plug in the point you're given and the new slope. Use y=mx+b format.
-1=-3/4*-4+b
Then solve for b.
-3/4*-4 is 3.
-1=3+b
Subtract 3 from each side.
-4=b.
So now you have the y-intercept and slope. All you have to do is plug it in.
y=-3/4x + -4 or y=-3/4 - 4
There's your answer!

Sally has two coins. The first coin is a fair coin and the second coin is biased. The biased coin comes up heads with probabilit
coldgirl [10]

Answer:

50%

Step-by-step explanation:

''What is the probability that she selected the biased coin?”

When we have n possible outcomes of an event and all of them have the same probability of appearance, then in theory each possibility has a probability 1/n of being the result of the event.

In this case the event is choosing randomly a coin out of 2, so no matter what the biased coin is or the results we get when we toss it, the probability of choosing the biased coin is ½ = 0.5 or 50%.

The fahrenheit and celsius scales are related by the equation F = 9/5C+32.
Ksivusya [100]

Step-by-step explanation:

by the equation u put down as

F=9/5C+32

since mexico is 81°f

81=9/5C+32

81-32=9/5C

49=9/5C

49*5=9C

245=9C

C=245/9

C=27.2°

to the nearest whole number

C=27°C
