Answer:
Step-by-step explanation:
42.6 divided by 0.07 is 608.571428
Regular division.
Answer:
y = all real numbers
x = all real numbers
In set notation/interval notation;
y∈(-∞,∞)
x∈(-∞,∞)
Step-by-step explanation:
1. Background information
The process of elimination involves manipulating an equation such that when the equations in the system are added, one variable is eliminated. Then one can solve for the other variable, finally, one substitutes the answer back in to find the eliminated variable. Therefore solving the system of equations.
2. The given information
Given the system;
(1) 4x + 5y = 4
(2) 8x + 10y = 8
3. Solving
Multiply the first equation by (-2)
4x + 5x = 4
*-2 *-2
-8x - 10x = -8
Add the first and second equations.
-8x - 10y = -8
+ ( 8x + 10y = 8 )
_____________
0
This means that y can be any real number, and hence x can be any real number.
Answer:
41+84=125 so therefore your answer is 125.
<u>Answer</u>
x ≥ -2
<u>Explanation</u>
The inequalities are solve the same way as algebra. This would be solve as follows.
-2x-1≤5
-2x≤5+1
-2x≤4
Divide both sides of the inequality by -2. This will change the sign from ≤ to ≥.
(-2x)/(-2) ≤ 4/(-2)
x ≥ -2
