Answer:
To find the value of y, you need to isolate the variable. To do this, add 21 to -12. This gives you 9. Now, you're equation is set as 9 = y. This means that the value of y is 9.
Step-by-step explanation:
Answer:
Good -T's
Step-by-step explanation:
2 for 16 would be 8 each
and buy 1 for 9.99 the other 1/2 off would be 5.00 so 15.00 is better then 16.00
Answer:
Segment addition postulate justify the statement if D is between A and B then Ad plus DB equals Ab
Step-by-step explanation:
This postulate states that if two points A and B are given and third point D lies on line segment AB only if distance between the points satisfy the equations AD+DB=AB.
Answer:
.
Step-by-step explanation:
The direct variation is defined as
where, k is constant of proportionality.
It is given that a direct variation function contains the points (-8,-6) and (12, 9).
Substitute x=-8 and y=-6 in the above equation.
Divide both sides by -8.
The value of constant of proportionality is 
. So, the required equation is
At x=12,
It means, the line passing through (12,9). Hence, the equation is correct.
Therefore, the equation of the function is .
Answer: 1/24
Step-by-step explanation: if you take 8 and change it to 1/8, you can multiply it by 1/3 and 1x1 is 1 and 8x3 is 24 so it’s 1 over 24 or 1/24
