Im not sure how to explain how to do a graph, but I hope this helps at least a bit!
~Direct Variation When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. In simpler terms, that means if A is always twice as much as B, then they directly vary. If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3.~
Let S = spoon
Let K = knife
1 knife is thee times the cost of a spoon, so it would be 3S
Now you have 9S + 12K = 82.80
We can replace the K with 3S:
9S +12(3S) = 82.80
Simplify the left side:
9S + 36S = 82.80
Add:
45S = 82.80
Divide both sides by 45"
S = 82.80 / 45
S = 1.84
One spoon cost $1.84
We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:
Knife = 1.84 x 3 = $5.52

Answer:
log3 (500)
Step-by-step explanation:
3 log3 (5) * log3(4)
We know that a log b(c) = log b(c^a)
log3 (5)^3 * log3(4)
We know that log a(b) * log a (c) = loga( b*c)
log3 ((5)^3 * 4)
log3 (125*4)
log3 (500)
Answer:
y=3x+2
Step-by-step explanation:
dont put 0 because it dont make sense
if you put 0 n the equation, you will not will get the right equation
