A function is an equation that has only one answer for y for every x. This means that:
Set A and Set C are functions because their y values don’t repeat.
Set B is NOT a function because the 2 in the y values repeats twice.
Hope I helped!
Answer:
x = 60
∘
Explanation:
As indicated by the markings, all the sides of this triangle are equal, and therefore all the angles of this triangle must be equal as well.
Let x be an angle,
so by the triangle sum theorem, we can say that:
3 x = 180
∘
x = 60

Answer:
r=s+5
Step-by-step explanation:
So, letsgo over what we know:
The regular price is r
The sale price is s
Now lets compare the difference between r and s:
10r = 5s
20r = 15s
30r = 25s
What is the difference between the r and s value in each situration?
Well, from what I can see, r is always 5 more than s.
This can be writen as:
r = s+5\
So this is our equation, for if you plug in any number for s, you will get an accurate r value.
For instance, if you say s is 25:
r=25+5
=
r=30
This looks just like the 30r=25s in the table above.
So:
r=s+5

Palarell lines has equal slop. so the slope of a line parallel to y = -x + 7 is equal to the slope of y = -x + 7 = -1.
The Burj Khalifa, a building in Dubai, United Arab Emirates, is about 828 meters tall. Brody is making a scale model of this building, using the scale 500 meters : 1 meter.
