We have to use the Distributive Property in this equation.
By the Distributive Property,
becomes
Now we need to isolate x. Remember PEMDAS?
Simplify the right side.
Domain values represent possible x values that are allowed to be plugged in and produce a y value. The values (in this case value) that are not allowed to be plugged in are what make the denominator zero (since you cannot divide by zero). Simply set the denominator equal to zero to figure out this value.
3x + 8 = 0
3x = -8
x= -8/3, this value is not in the domain.
These are the the letters that look the same when reflected across the line B,C,D,E,H,I,K,O,X
Answer:
; line D in the options.
Step-by-step explanation:
The set of equations has no solutions if the two lines are parallel. A quick way to create a parallel line is to solve for y, put it in slope-intercept form. Else, as long as the cofficient of x and y are in the same ratio (in this case 1:1), the two lines are parallel, you just have to be careful not to pick the same line again!
The condition 
makes sure you are still getting lines (else you would get rid of both x and y); the condition 
makes sure you're not picking line A again, just written in a different form.
Now that we have the options:
A and C have a different ratio for the coefficient of x and y (2:1 and 1:2) so are not good.
Choice B is just a more complicated way to write the same line, you can see by dividing both sides by 2 and get back x+y=2.
Line D is correct.
To find how much 43% of 210 is, we do a part/whole=percent/100, so a/210=57/100, 210•57=11970/100=119.70, so that means that 210-119.70=90.30, so 210+90.30=300.30 as the final cost
