Lindy works at a pizza restaurant and gets a 10% employee discount. She knows that if she orders d drinks and a medium pizza with t toppings, her total cost can be found using this expression: 0.90(2.25d + 1.40t + 6). What is the total cost for Lindy and her friends to order 4 drinks and a medium pizza with 3 toppings?

$17.28.

Step-by-step explanation:

In the expression, d represents the number of drinks she orders and t represents the number of toppings.

In this case, she orders 4 drinks and 3 toppings, so d = 4 and t = 3.

0.90(2.25d + 1.40t + 6)

= 0.9(2.25 * 4 + 1.4 * 3 + 6)

= 0.9(9 + 4.2 + 6)

= 0.9 * 19.2

= 17.28

So, the total cost for Lindy and her friends will be $17.28.

Hope this helps!

1.true 2.false? ? i think. .

step-by-step explanation:

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'.
