What is the x-intercept of the line with the equation  <br>8x-1/3y=16
Maslowich
One thing is you need to get x on one side and y on the other :) 
8x-1/3y=16
Just like any equation you subtract 8x
8x-1/3y=16
<u>-8x              -8x
</u>-1/3y=16-8x
Now you want y all alone. So you divide. To me I think you divide by -3. But you might want to check and divided by
by -1/3 (just in case)
<u>-1/3y=16-8x
</u>        -3 
y=-5.33(3 is repeating) - 2.6666667x

I really do this help you out! :D

A bag contains purple marbles and white marbles, 96 in total. The number of purple marbles is 6 less than 5 times the number of
love history [14]
<em /><em>PURPLE MARBLES=P
WHITE MARBLES=W

</em>First, write out an equation showing the number of purple marbles.
P=5W-6
Then, write out the main equation.
W+P=96
W+5W-6=96
Add 6 to both sides.
W+5W=102
6W=102
Divide both sides by 6
W=17
Now that we know there are 17 white marbles, we can go back to the equation about how many purple marbles there are. 
P=5W-6
Plug in the value for W, which is 17.
P=5(17)-6
P=85-6
P=79

To make sure your answer is correct, check your work by plugging in the values for P+W=96.
79+17=96
Answer: There are 79 purple marbles.

Suppose that a1, a2, a3, . . . is an arithmetic sequence, in which a3 = 19 and a14 = 96. Find a1.
katovenus [111]
Uhhh I think you have to add 19 and 14 which shall give you the answer to a1 so it should be 33 but then I think you divide 33 and 96 or you will multiply 33 and 96
