X=number of games played
just do simple multiplication
remember that orded pairs are (x,y)
x=5
y=0.50(5)+3
y=2.5+3
y=5.5
orderd pair is (5,5.5)
x=10
y=0.50(10)+3
y=5+3
y=8
ordered pair is (10,8)
x=20
y=0.50(20)+3
y=10+3
y=13
ordered pair is (20,13)
(5,5.5)
(10,8)
(20,13)
Answer:
-4 ≤ x ≤ 6
Step-by-step explanation:
When we talk of the domain, we are referring to the possible x-values
from the diagram, we can see that we have the x-values at -4 and 6
The dotted line means that -4 and 6 are in the domain
Thus, the two points represent the end and starting point of the domain
Writing this in interval notation, we have the representation as;
-4 ≤ x ≤ 6
Answer:
12
Step-by-step explanation:
The second diagram is most helpful for finding the surface area.
- Find the area of the middle square: 2 * 2 = 4
- Find the area of the triangle using <em>A = 1/2*B*H,</em> so <em>A = </em>1/2 * 2 * 2 = 2
- Since there are 4 triangles, the surface area of all the triangles is 2 * 4 = 8
- Add the surface area of the triangles with the surface area of the square to get the total surface area: 8 + 4 = 12

0.17/30 = x/450 <em>Use proportion</em>
76.50 = 30x <em>Cross multiply</em>
2.55 = x <em>Divide 30 both sides</em>
