What is the graph of the function rule? Y=|5x|-2
2 answers:
Step-by-step explanation:
Y=|5x|-2
Given equation y is in vertex form
y = |x-h| + k
Y=|5x|-2
there is no h so h=0 and k= -2
vertex is (h,k) so its (0,-2)
now make a table. plug in some value for x before and after 0
x y= |5x| -2
-2 y = |5(-2)| - 2= |-10| -2 = 10-2 = 8
-1 y = |5(-1)| - 2= |-5| -2 = 5-2 = 3
0 y = 0 - 2= -2
1 y = |5(1)| - 2= 3
2 y = |5(2)| - 2= 8
Now we graph the table
the graph is attached below

Answer:
Step-by-step explanation:
The given equations are:
(1)
and (2)
Now, simply adding equation (1) and equation (2), we get
Now, substituting the value of x=6 in equation (2). we get
Thus, the values of x and y are 6 and 1 respectively.
In order to solve the system of solution, beau can see that in both the given equations, coefficient of y is same and is with opposite sign, thus simply adding both the equations will eliminate y and she will get the value of x and then substituting the value of x in any of the equations, she can get the value of y. With this, she can get closer to the solution.
