3x - 2x + 4 = 5x - 4x - 8
First, let's focus on the left side of the problem (3x - 2x + 4). Let's subtract 3x - 2x which will get us 1, and since a variable by itself is considered 1, we can just put the variable.

Second, now let's focus on the right side of the problem (5x - 4x - 8). Subtract 5x - 4x to once again get 1. Replace it with the variable and leave the rest.

Third, we can now cancel out x on each side. This will leave us with 4 = -8, which is false, meaning that there is no solution to this problem.
Answer:
m^76
Step-by-step explanation:
m^-43 + 199
= m^76
hope this helped :)
Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
Answer:
The linear function is
.
Step-by-step explanation:
A linear function is given by the formula,
, where m is the slope and c is the y intercept of function.
The following two points lie on the graph; (0,-1) and (3,-10)
Inserting this two points we get,

,
solving this two equations we get,
m = -3 and c= -1
Thus, the linear function is given by,
