1. mrs. wendt called drano plumbing company to fix a leak. their fee is $35 for the
service call, and $42 per hour.
a) build a table.

b) write an equation for the amount she would pay for ‘x’ hours:


c) write and solve an equation to find out how long they worked if her bill was $140.
equation:
solution:

Step-by-step explanation:

a)

42 x 1 = 42

42 x 2 = 84

42 x 3 = 126

42 x 4 = 168

42 x 5 = 210

I don't know how long you table has to be so I just went to 5.

b) I don't really understand this part, so don't take my word for it, but I THINK the answer is 42x. I may be wrong.

c) Your equation for this would be 35 + 42x = 140.

This is you equation because the fee was $35 and she paid $42 per hour, and that all added up to be $140.

Now the way you would solve this equation is, you would rewrite the equation:

35 + 42x = 140

Step 2: Simplify both sides of the equation.

42x+35=140

Step 3: Subtract 35 from both sides.

42x + 35 − (35)=140 - (35)

42x = 105

Step 4: Divide both sides by 42.

42x/42  =  105/42

x =  5/2 or 2.5

I hope that this helped.

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'.
