Answer:
domain = {x|xER}
range = {y|y≥0,yER}
Step-by-step explanation:
|x| means the absolute value which in this case is the distance from 0. On a graph this function would look like a v and would mean it would have infinite x-values since it is opening upwards in both directions.
For the range the vertex of this function is (0,0), if the x-coordinate were 0 the y-coordinate would be 0 because the absolute distance from 0 is 0. for another x-coordinate say -2 the absolute distance from 0 is 2 meaning the y-value is 0 since y=|x|, making the coordinate (-2,2) meaning the range is every y value must be above 0 since there is no way for the y-value to be negative
Answer:
m=-3
Step-by-step explanation:
move the -22 to the other side by adding 22 on both sides:
m-22+22=-25+22
Simplify:
m=-3
Answer: m=-3

Step-by-step explanation:
ANSWER
x=3, y=-4
EXPLANATION
The given system is :
First equation:
Second equation:
Let us multiply the first equation by 7 to get,
Third equation;
Let us multiply the second equation too by 10 to get,
Fourth equation:
Subtract the fourth equation from the third equation:
Divide both sides by 59.
Put y=-4 into the second equation and solve for x.
The solution is x=3, y=-4
Answer:
X ie equal to 3
The first option is correct
