 J = 5w + 5

B = 4w + 12

They will have the same amount in week 7.

Step-by-step explanation:  Look at the difference from one week to the next: for Jocelyn it's 5 per week, for  Ben it's 4 per week

That's where the 5w and 4w come from.  

Then look at the starting amounts in week 0: for J it's 5, for B it's 12.

Whatever they have in any future week (if no withdrawals or interest are made)  is the starting amount + the amount added per week.

To find our when they will have equal amounts, write an equation with the two expressions:

5w + 5 = 4w + 12   Then solve for w.

5w -4w +5 -5 = 4w-4w +12 -5  Subtract 4w and 5 from both sides ("cancel" 0's)

w = 7

They will have equal amounts in the 7th week.

You can substitute 7 for w in the equation to check:

5(7) + 5 = 4(7) + 12

35 + 5 = 28 + 12

40 = 40   True!  They will each have $ 40 in week 7.

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'.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
