Answer:
(28000,40000) or $28,000 to $40,000
Step-by-step explanation:
plug in values as V and solve for x:
12,000=22,000-0.25x
-10,000=-0.25x
40,000=x
15,000=22,000-0.25x
-7,000=-0.25x
28,000=x
an interval notation always has the lower value first so its:
(28000,40000) or $28,000 to $40,000
Answer: A) y=25, B) y=10 C) y=-5 D)y=-20
Step-by-step explanation:
So whenever you have a question like this just plug in the values.
A) x=0
y= -3x+25 will now turn into y=0+25, so y=25
B) x=5
y= -3x+25 is now y= -15 +25, so y=10
C) x=10
y= -3x+25 is now y= -30+25, so y=-5
D) x=15
y=-3x+25 is now y= -45+25, so y=-20
Answer:
f(-2) = (3/4)(-2) - 4 = -3/2 - 4 = -1.5 - 4 = -5.5
Step-by-step explanation:
Write f(x) = 3/4 x - 4 as f(x) = (3/4)x - 4 for clarity.
Now substitute -2 for x in f(x) = (3/4)x - 4:
f(-2) = (3/4)(-2) - 4 = -3/2 - 4 = -1.5 - 4 = -5.5
First divide 3 both side
Than move 4 to another side
Than divide by 2
