At a shoe store a sales person earns a weekly salary of $150.a salesperson is also paid $2.00 for each pair of shoes he or she sells during the week what is the algebraic expression

150 + (2x)

Step-by-step explanation:

At a shoe store a sales person earns a weekly salary = $150.

He or she also paid for the sale of each pair of shoes = $2.00

Let the number of  pairs of shoes sold be 'x'

the commission on the shoes sold = 2(x)

So the algebraic expression for her/his weekly pay would be

150 + (2x)

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
