Simplify -7 + [5 + (-12)÷3] -6 -34/3 -8

Answers

Answer 1
Answer:

You will start with division

(-12)/3 = -4

and than everything in the [ }

so that means 5 + -4 = 1

-7 + 1

The answer is -6
Answer 2
Answer: -7 + [5 + (-12) / 3] - 6 - 34/3 - 8 = -7 + [5 - (12/3)] - 76/3 = -7 + [5 - 4] - 76/3 = -7 + 1 - 76/3 = -94/3 or -37 1/3

Answers

If x < - 2 and x ∈ { - 5, - 2.6, - 2, - 0.8, 1, 1.5 }
- 5 < - 2 and - 2.6 < - 2
The solution set is:
A ) { - 5 , - 2.6  }

If x < - 2 and x ∈ { - 5, - 2.6, - 2, - 0.8, 1, 1.5 }

- 5 < - 2 and - 2.6 < - 2

The solution set is:

Factor completely x2 − 10x + 25.(x − 5)(x − 5)

(x + 5)(x + 5)

(x + 5)(x − 5)

(x − 25)(x − 1)

Answers

The answer is:
(x - 5) (x - 5)   The equation is a perfect square. 
(a - b) (a - b)   The "formula" goes a^2 - 2ab + b^2 for this equation so when you expand out the brackets x to x, x to 5 then 5 to x and 5 to 5 ( a x a, a x b, b x a, b x b) then collect all the like terms it turns into the equation above.

What is the slope of the line that passes through the points (1,−6) and (−2,−8)?

Answers

Answer:

(2/3)x-(20/3)

Step-by-step explanation:

Line A has a slope of 6/10 and a line B has a slope of 3/5 are both lines parallel?

Answers

Answer:

Nope!

Step-by-step explanation:

If you look at both of the slopes, you can tell that 6/10 is actually equivalent to 3/5. 3/5 is the simplified version of 6/10. So realistically, they'd line up perfectly and not be parallel!
