So first we solve and simplify

9-4(x-y)=-6x+6
distribute using distributeive property of multiplication which is a(b+c)=(ab)+(ac)
so -4(x-y)=-4x+4y
9-4x+4y=-6x+6
add 6x to both sides
9+2x+4y=6
subtract 9 from both sides
2x+4y=-3
only B matches this
B is the correct answer
(I don't know what standard form is but I know what simplified is)
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:
Step-by-step explanation:
We first denote the inequalities of the number of shirts and skirts.
#Since you cannot make a negative number of shirts or skirts, the inequalities will be written as:
#We then represent the inequality of material.
-The material size is a production constraint as only 500 yards of material is available for use.
-The inequality is therefore written as:
#We then represent the inequality of time.
-The material size is a production constraint as only 800 hours available for use.
-The inequality is therefore written as:
We combine the three inequalities to represent the constraints
All you have to do is measure angle c and redraw it and call it d
2+1=3
2x1=2
Hope I helped!
