Answer:
x+5
Step-by-step explanation:
so first you would divide by x (which means you would multiply x+2 by -x)
x^2 + 7x + 10
-x^2 - 2x
5x + 10
then you would divide by 5 (which means you would multiply x+2 by -5)
5x + 10
5x +10
0
So then to check it you would multiply x+5 by x+2
(x+5)(x+2)
x^2 + 2x + 5x + 10
then simplify to get
x^2 + 7x + 10
we have that
y = 3x - 2
10(x+3/5)=2y------> the second equation----->divide by 2 both sides
5(x+3/5)=y-----> y=5x+3
y=5x+3------> second equation written in slope-intercept form
so
case A) y=5x+3/10-----> is not equal to y=5x+3
case B) y=5x+3--->is equal to y=5x+3---------> is the answer
case C) y=1/5x+3/25-------> is not equal to y=5x+3
case D) y=1/2x+6-----> is not equal to y=5x+3
therefore
the answer is the option
B) y=5x+3
Y = 16, -16
explanation: the absolute value bars make the expression inside positive, if they were negative to begin with. so, a negative number like -16 becomes 16, and a positive number like 16 still stays the same
Answer:

Step-by-step explanation:
Answer:
There is a whole range of speeds at which you are allowed to drive, not just one. In cases like this where there is more than one correct answer, we use inequalities, not equations, to represent the situation.
Inequalities are mathematical statements that define a range of values. They are easily recognizable because they contain the symbols <, ≤,>, or ≥.
