9 x 1 = 9
9 x 2 = 18
9 x 3 = 27
9 x 4 = 36
9 x 5 = 45
9 x 6 = 54
9 x 7 = 64
9 x 8 = 72
9 x 9 = 81
9 x 10 = 90
Distribute the 3 to the parentheses. Q=3r+3/r
Next multiply both sides by r to get rid of the division sign.
Qr=3r+3
Subtract 3r on both sides and you get Qr-3r=3
Since both numbers have an r in it, we can factor out the r
r(Q-3)=3
Then we divide Q-3 on both sides
r=3 / (Q-3)
The x-intercept of the line 3x - 5y = 7 is at point ( 7/3, 0 ).
<h3>What is the x-intercept of the line?</h3>
Given the function;
X-intercept occurs on the graph when y=0. Hence, to determine x-intercept, we substitute in 0 for y and solve for x.
3x - 5y = 7
3x - 5(0) = 7
3x - 0 = 7
3x = 7
x = 7/3
Hence, we have a point ( 7/3, 0 ).
The x-intercept of the line 3x - 5y = 7 is at point ( 7/3, 0 ).

Answer:
The number of machines to complete job in 2 hours is 6.
Step-by-step explanation:
Using the relation of the rate of each one machine and knowing that adding up both rates.
Rate R = 
'x' is the job
Rate S = 
'x' is the job
So, using the equation of rates
Rate total is going to be a job in 2 hours so = 
<em>adding up</em>
<em>factoring the x</em>
<em>simplifying</em>
x= 
x= 6
Answer:
The correct solution is C (x> -2)
