1) 
The graph of the above equation is attached in the attachment below.
For all the values from negative infinity to -4, the function is positive.
X ∈ (-∞,-4]
2) 
To find the x- intercept, plug y =0



x intercept = (2,0)
To find the y- intercept, plug x=0


Y- intercept = ( 0,3)
3) 
Y- intercept = (0,13)
x- intercept = (13,0)

Slope intercept of line 
Where, m is the slope and b is the y- intercept.
Plugging point A and the slope in the y- intercept to find the value of b.


Equation of line AB: 
Slope of BC = 
Plug C = (0,-4)

b=-4
equation of line BC= 
Slope of line AC = 
Equation of line AC = 
Y intercept of AB = 
Answer:
y-intercept: (0, -5)
x-intercepts: (-5, 0) , (1, 0)
Answer:
$152.33
Step-by-step explanation:
123.85 x 0.05 = $6.19
123.85 x 0.18 = $22.29
123.85 + 6.19 + 22.29 = $152.33

Multiply both sides by 3, because 3 is our denominator (bottom number in a fraction), and we want to get rid of the denominator.
3 × (v + 9) = 8 × 3
Simplify.
3v + 27 = 24
Then, subtract both sides by 27.
3v = 24 - 27
Simplify.
3v = -3
Divide both sides by 3.
v = -1

Answer:
The actual dimensions of the kitchen are
by 
Step-by-step explanation:
step 1
Find the scale of the drawing
To find the scale , remember that is equal to the ratio of the corresponding dimension in the drawing divided by the corresponding actual dimension
so

step 2
To find the actual dimensions of the kitchen, divide the dimension in the drawing by the scale
so
