Answer:
Step-by-step explanation:
47.91 + 23.96 + 35.09 = 106.96 <== actual answer
now if u were wanting an estimate, I would have done :
48 + 24 + 35 = 107
Answer:
(3,1)
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other
y = 3x-8
y = 4-x
3x-8 = 4-x
Add x to each side
3x+x-8 = 4-x+x
4x-8 = 4
Add 8 to each side
4x-8+8 = 4+8
4x = 12
Divide each side by 4
4x/4 =12/4
x=3
Now we can find y
y = 4-x
y = 4-3 =1
Answer:
The quadratic equation has two complex solutions.
Step-by-step explanation:
5x² + 6x + 2 = 0
To know the the correct answer to the question, we shall determine the discriminant of the equation. This can be obtained as follow:
5x² + 6x + 2 = 0
ax² + bx + c = 0
Comparing the above equation, we can obtain:
a = 5
b = 6
c = 2
Discriminant (D) =?
D = b² – 4ac
D = 6² – (4 × 5 × 2)
D = 36 – 40
D = – 4
Since the discriminant of the equation is less than 0, it means that the equation has no real root ( i.e the equation has two complex solution).
