Answer:
See below.
Step-by-step explanation:
The domain and range are correct.
The relation is a function because no x value is used more than once.
Answer:
See attachment
Step-by-step explanation:
We want to graph the following equation:
x-y+1=0
and
3x+2y=12
For the first equation: x-y+1=0
When x=0, we have 0-y+1=0---->y=1
We plot the point (0,1)
When y=0, we have x-0+1=0---->x=-1
We plot (-1,0)
We draw a straight line through these two points to get the graph of this line.
For the second equation: 3x+2y=12
When x=0,y=6. So we plot (0,6)
When y=0, x=4, So we plot (4,0)
We draw another straight line through them to obtain the graph in the attachment.
Answer:
66°
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°.
__
79° +x +35° = 180°
x = 180° -114° . . . . . . . . subtract 114° from both sides
x = 66° . . . . . simplify
Just substitute in values into the equation corresponding to the x,y:
To solve for a missing y value, substitute the corresponding x value, so 0, 2.33, and 6.25.
To solve for x, set the equation equal to the x and solve.
x's:
0
.25
2.33
4.5
6.25
y's:
5
5.75
14.99
18.5
23.75

By scenario, you could make that equation 3x + 5 the rental time of a very cheap carper cleaner service. They charge 5 dollars as the static fee, and 3 dollars per hour
22.90*1.05=24.045
sales tax is 5% added to 100% of the original cost making the actaul cost including tax $24.045
