Answer:
11. (x-2)/(x+8)
12. 9+t
13. h = 2A/b
Step-by-step explanation:
11. Since x is used to represent the number, 2 less than a number is x-2. 8 more than a number is x+8. The quotient of the first and second of these is the first one divided by the second one:
... (x -2)/(x +8) . . . . . parentheses are required unless the expression is typeset:
12. Apparently, we're to assume the salesman keeps on driving. If he had any sense (or a good union), he would stop after 9 hours. t hours added to 9 is ...
... 9 + t
13. Divide by the coefficient of h.
... h = A/((1/2)b) = 2A/b
Given:
There are given the equation:
Explanation:
From the equation (1):
Put the value of x into the equation (2):
So,
From the equation (2):
Now,
Put the value of y into the equation (1):
So,
From the first equation:
Final answer:
Hence, the ordered pair of the solution is shown below:
Answer:
< 3
Step-by-step explanation:
Hope this helps:)
Answer:
Step-by-step explanation:
Given:
The magnitude, v=12
The angle 
it makes with the positive x-axis =
Now for a vector (x,y)
; and
Therefore:
Similarly:
Recall that:
Therefore: 
The vector in the form ai+bj is therefore:
Step-by-step explanation:
(1,1.5) is the solution but (12,4) is not the solution of given equation.
1.5=1/4×1+5/4(which is true)
4=1/4×12+5/4(which is false)
