Answer:
Since from the laws of exponents we have that x−n=1xn , it implies that we may write 18=8−1 . 18=123=2−3.
Step-by-step explanation:
Answer:
The relation passes the vertical line test.
Step-by-step explanation:
When you graph the points, a vertical line can be drawn through them without hitting another point.

Answer:
The actual car is 13.5 feet long.
Step-by-step explanation:
1 : 18
9 inches : x inches
1 * 9 = 18 * 9
Thereby x = 162 inches
162/12 = 13.5 feet
Answer:
m=3/4
Step-by-step explanation:
First, let us remind ourselves of the slope formula: m=rise/run=(
-
)/(
-
)
Let's pick two points from the graph to work with. Let's do (3,-6) and (-1,-9).
And let 3=
, -6=
, -1=
, -9=
.
1. Substitute the values into the slope formula: [-9-(-6)]/(-1-3)
2. simplify the expression: [-9-(-6)]/(-1-3)=(-9+6)/-4=-3/-4=3/4
3. As a result, the slope of the line is 3/4
