The precision is 10 inches. This is because the 0 at the end of the number is not considered a significant digit in the form in which the number is written, and hence "80 inches" is to be considered a roundoff from a number which can be from 75-85 inches.
Y= -3/4x - 5
slope intercept form is y=mx + b
the mx is your slope, in this equation -3/4
the b is the y intercept, where the line first crosses the y axis. in this equation -5.
hope this helps :)
So all you do is the exponents first the add multiply and divide until you get your answer. C
Answer:
143,344
Step-by-step explanation:
Let d represent the total number of registered doctors. The given relation is ...
0.323d = 46,300
Dividing by the coefficient of d, we get ...
d = 46,300/0.323 ≈ 143,343.7
The total number of registered doctors was about 143,344.
Answer:
x = 1
Step-by-step explanation:
Subtract the right side of the equation and simplify:
9x -4 -6x -2(x +1) +5 = 0
9x -6x -2x -4 -2 +5 = 0 . . . . . eliminate parentheses
x -1 = 0 . . . . . . . . . . . . . . . . . . collect terms
x = 1 . . . . . . . . . . . . . . . . . . . . . add the opposite of the constant
_____
<em>Check</em>
Substitute the value of x where x is found in the equation.
9·1 -4 -6·1 = 2(1 +1) -5
9 - 4 - 6 = 2·2 -5
-1 = 4 -5 . . . . . true. The answer checks OK.
