Answer:
D. Every real number is also rational.
Answer:
1 - 4/5-(-1/5)
Step-by-step explanation:
1. - 4/5-(-1/5)
= -0.8+0.2 (if there is a minus sign inside and outside of the parenthesis, when we destroy that parenthesis, both the minus signs will be multiplied and becomes a (+).) (Making it to the percentile).
= -0.6
2. - 4/5-1/5
= -0.8-0.2
= -1
3. -(4/5+1/5)
= -(0.8+ 0.2) (Making those to the percentile).
= -(1) = -1 (When we destroy the parenthesis, if there is a minus sign outside the parenthesis, the result will become a minus.)
From the above expressions, we can see that after calculating, the second and third expressions have the same value, i. e. -1. However, the result of the first expression is different, and we get -0.6. So option one is the right choice.
Answer:
<u>-2</u>
Step-by-step explanation:
Find two points which lie on the line :
- Take (-2, -1) and (-1, -3)
Formula for slope (m) :
- m = y₂ - y₁ / x₂ - x₁
- m = -3 + 1 / -1 + 2
- m = -2/1
- m = <u>-2</u>
Answer:
A=
Step-by-step explanation:
a−3=a1(5)
Step 1: Simplify both sides of the equation.
a−3=a1(5)
a+−3=5a
a−3=5a
Step 2: Subtract 5a from both sides.
a−3−5a=5a−5a
−4a−3=0
Step 3: Add 3 to both sides.
−4a−3+3=0+3
−4a=3
Step 4: Divide both sides by -4.
-4a/-4 = 3/-4
<h3>Your final answer is a=-3/4</h3>
