Answer:
6. -2.5 + 3 = 0.5
Part B. -2.5 + x = y
4. a. Yes
b. No
c. No
d. Yes
1. C. -1/8 points
3. a. -3.7 + 8 = positive number 8 = a. 4/3 = d.
b. -8 - 1/1/3 = negative number -8 = b, c. -5 = b, d.
c. -8 + 8 = 0 -4.9 = b, d. -5.4 = b, d.
d. -4.52 + -4.9 = negative number 3.8 = a, d. 3.86 = a, d.
Step-by-step explanation:
Those are the correct answers.
The solution of are 1 + 2i and 1 – 2i
Solution:
Given, equation is
We have to find the roots of the given quadratic equation
Now, let us use the quadratic formula
--- (1)
Let us determine the nature of roots:
Here in a = 1 ; b = -2 ; c = 5
Since , the roots obtained will be complex conjugates.
Now plug in values in eqn 1, we get,
On solving we get,
we know that square root of -1 is "i" which is a complex number
Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i

Answer:
x=10
Step-by-step explanation:
Let's solve your equation step-by-step.
40−x=3x
Step 1: Simplify both sides of the equation.
40−x=3x
40+−x=3x
−x+40=3x
Step 2: Subtract 3x from both sides.
−x+40−3x=3x−3x
−4x+40=0
Step 3: Subtract 40 from both sides.
−4x+40−40=0−40
−4x=−40
Step 4: Divide both sides by -4.
−4x
−4
=
−40
−4
x=10
