Answer:
y = 1/2x -3
x=-2 ⇒ y = -4
x=-1 ⇒ y = -3.5
x=0 ⇒ y = -3
x=1 ⇒ y = -2.5
x=2 ⇒ y = -2
Step-by-step explanation:
Hi, to answer this question we have to isolate y:
x - 2y = 6
-2y =6-x
y = (6-x)/-2
y = -3+1/2x
y = 1/2x -3
Now, we have to create a table with the next values (see attachment)
x=-2 ⇒ y = 1/2x -3 = 1/2(-2)-3= -4
x=-1 ⇒ y = 1/2x -3 = 1/2(-1)-3= -3.5
x=0 ⇒ y = 1/2x -3 = 1/2(0)-3= -3
x=1 ⇒ y = 1/2x -3 = 1/2(1)-3= -2.5
x=2 ⇒ y = 1/2x -3 = 1/2(2)-3= -2

Answer:
48 miles per hour
Step-by-step explanation:
first I would convert everything to hours It makes it easier. That means that 3 hours and 45 mins becomes 3 3/4 hours So now you have 180/3.75 = the rate. To find the answer, simply divide that, and you get 48. 48 miles per hour
Answer:
15.90
Step-by-step explanation:
The formula for standard deviation, σ, of a population is

We can use a table to organize the calculations.
<u> x </u> <u>x - µ </u> <u>(x - µ)²
</u>
212 -18 324
249 19 361
212 -18 324
248 18 324
239 9 81
212 -18 324
216 -14 196
234 4 16
<u> 248 18 324</u>
2070 2274
Sum= 2070
N = 9
µ = Sum/N = 2070/9 = 230

<span>30% off the regular price means 100% - 30% = 70%
and 70% = 0.7
so 0.7 x 328 = 228.9

Answer:
Option: B is correct.
( Preserves the shape and size of the figure )
Step-by-step explanation:
- An ISOMETRIC TRANSFORMATION (RIGID MOTION) is a transformation that preserves the distances and/or angles between the pre-image and image.
- The isometric transformations are reflection, rotation and translation and combinations of them such as the glide, which is the combination of a translation and a reflection.
Hence, option B is correct.
Preserves the shape and size of the figure.
