3 gray cats enjoy! (the rest of the typing here you may ignore its just to get 20 charactors) btw take 9/3 to get 3 gray cats because for every 3 calico there is one gray
Answer:
D=-4<0, the equation has no real solutions, it has two imaginary solutions.
Step-by-step explanation:
The quadratic equation
has coefficients
a=1,
b=4,
c=5.
The discriminant D is the expression

Hence,

Since the discriminant is negative, the equation has no real solutions, it has two imaginary solutions.
Answer:
B
Step-by-step explanation:
Count the units
Solución 1: 2(x) + 3(y) = 80
solución 2: 3(x) + 2(y) = 70
3(y) + 2(x) = 80
2(y) + 3(x) = 70
2y = -3x + 70
y = -3x÷2 + 35
2x + 3(-3x÷ 2+35) = 80
-5x÷2 = -25
-5x = -50
5x = 50
x-intercept: 10
x = 10
y = -3x÷ 2+35
y = -(3÷2)(10)+35 = 20
x-interpcet: 10
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480
-8y + x = 0
4y + x = 480
x-intercept (solución 2)
x = -4x + 480
x-intercept (solución 1)
4y + 180 - 8y = 0
-12y = 480
y-intercept: 40
x-intercept: 320
Buena Suerte!
