Answer:
1) Domain = -3 ≤ x ≤ 2
Range = -4 ≤ y ≤ 5
Function? No
Step-by-step explanation:
From the given graph, we have;
The domain of the dot plot = -3 ≤ x ≤ 2
The range of the dot plot = -4 ≤ y ≤ 5
From the given data plot, we have that a straight line joining the data points is in the form of an arrow head with one value of the input (independent) variable, 'x', giving two values of the output (dependent) variable, 'y', such as the input, x = 1, gives two output, y = -2, and y = 3
Therefore, the relation is not a function as one input value produces two output values.

if they sold 20 t-shirts and made $40.
$40 ÷ 20 = $2
Answer:
SM = 13
Step-by-step explanation:
M is the midpoint of ST, then
SM = MT , that is
2x + 3 = 4x - 7 ( subtract 4x from both sides )
- 2x + 3 = - 7 ( subtract 3 from both sides )
- 2x = - 10 ( divide both sides by - 2 )
x = 5
Then
SM = 2x + 3 = 2(5) + 3 = 10 + 3 = 13
Answer:
The cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Step-by-step explanation:
Let us assume this is a simple interest scenario.
Let D be the cost of desktop
Let L be the cost of laptop
Given- the laptop cost $150 more than the desktop.
So,
The total finance charge for 1 year is given by :
Substituting the value of L here, we get;
=>
=>
=>
=>
D = $1750
As
So,
L = $1900
We can check this :
=>
=>
So, the cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
(y+5) =(5/4)(x-8)
4(y+5)=5(x-8)
4y+20=5x-40
5x-4y=60
