for the equation is, x = -4 - 5i

The  solution will be, x = -4 + 5i

for the equation is, x = 4 + 5i

The  solution will be, x = 4 - 5i

for the equation is, x = 5 - 4i

The  solution will be, x = 5 - 4i

<h3>Quadratic equation defind as:</h3>

Any equation in algebra that can be written in proper format as where x stands for an unknown, where a, b, and c stand for known numbers, and where a 0

<h3>According to the given information:</h3>

If (a + bi) is a complex number and a quadratic equation has one solution,

The second solution to the equation will be the conjugate of the first.

Consequently, the alternative solution will take the form of (a - bi).

for the equation is, x = -4 - 5i

The  solution will be, x = -4 + 5i

for the equation is, x = 4 + 5i

The  solution will be, x = 4 - 5i

for the equation is, x = 5 - 4i

The  solution will be, x = 5 - 4i

In AQRS, m2 Q = 63º, mZ R = 70°, and m2 S= 47°. Which side of AQRS is the
8090 [49]

Answer:

D. QR.

Step-by-step explanation:

1) in ΔQRS the side QR is opposite the angle S (47°); QS is opposite the angle R (70°); RS is opposite the angle Q (63°);

2) the rule is: greater angle is opposite the longer side;

3) according to the rule the angle 'S' is the smallest, then the side QR is the shortest.

Your class raised money by selling hot dogs and hamburgers. Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold
LenKa [72]

Answer:

Number of hot dogs sold =  56

Number of  hamburgers sold = 52

Step-by-step explanation:

Let

Number of hot dogs sold = x

Number of  hamburgers sold = y

We can make equation from given equations:

0.50x+1y=80 (Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold for $1 (one dollar). The total money raised by your class was $80. )

x+y=108  (Together you sold 108 hot dogs and hamburgers.)

Now we cam solve these system of equations to find value of x and y

0.50x+y=80--eq(1)\\x+y=108--eq(2)

Subtract both equations to get value of x:

0.50x+y=80\\x\:\:\:\:\:\:\:\: + y=108\\-\:\:\:\:\:\:\:\: -\:\:\:\:\:\: -\\---------\\-0.5x=-28\\x=\frac{-28}{-0.5}\\x=56

We get value of x = 56

Now putting value of x in equation 2 to find value of y

x+y=108\\56+y=108\\y=108-56\\y=52

So, we get y = 52

Therefore,

Number of hot dogs sold = x = 56

Number of  hamburgers sold = y = 52
