Answer:
D
Step-by-step explanation:
y - 4 = 7(x - 6) Remove the brackets
y - 4 = 7x - 42 Add 4 to both sides
y = 7x - 42 + 4
y = 7x - 38
Note when you put this in slope, y intercept form, the ordered pair is easier to find.
Let x = 5
y = 7*5 - 38
y = 35 - 38
y = -3 (5,4) isn't right
Let x = 6
y = 7*6 - 38
y = 42 - 38
y = 4 That does not work either.
The answer is D
So the unit price refers to the cost of one unit i.e if 24 are being sold for $6.50 what is the cost for just 1 so to calculate just one do the The price divided by the number of units e.g 6.50/24 which is around 0.27
In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
The goat can go in a circle
the rope's length is the radius
area=pir^2
area=pi5^2
area=25pi square meters
if we use pi=3.14
area=78.5 square meters
