 The distributive property
multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products 

8x45= 360
8x40=320
8x5=40
8x40 + 8x5 = 360

Answer:

∠ XZY ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle, that is

sinXZY = \frac{opposite}{hypotenuse} = \frac{XY}{YZ} = \frac{6}{15} , then

∠ XZY = sin^{-1} (\frac{6}{15} ) ≈ 23.6° ( to 1 dec. place )

1. Petra works as a delivery person for a restaurant. The graph shows a linear model for her
Charra [1.4K]

Answer: The points are, the top left one, (21,3) and the one on the bottom is (6, 12)

Step-by-step explanation: For the slope, we label one of the points, with y or x. For example, (21, 3) we would label 21 either y1 or x1. Say we put y2, then 3 would be x2. Moving on, (6,12) this time we could label 6 as either y1 or x1. Same thing, but this time we are going to label 6 as y1 and 12 x1. Again, it’s DOES NOT matter what you label them as.

Now to solve it, remember y numbers always go on top! M which is slope. M = y2 - y 1 / x2 - x 1 or with the numbers M = 21 - 6 / 12 - 3 = 15/9 simplified = 5/3
