Answer:
Correct
Step-by-step explanation:
4y = 3x Divide each side by 4
4y ÷ 4 = 1y
3x ÷ 4 = 0.75x
12y = 9x Divide each side by 12
12y ÷ 12 = 1y
9x ÷ 12 = 0.75x
We can see in both equations that 1y = 0.75x
(1y = just y) So the constant of proportionality can be written as y = 0.75x
All of your explanations and descriptions are accurate.
If you're trying to say what's 90% of 63, you divide 63 by 10 which is 6.3 then times by 9 which is 56.7
Answer:
Step-by-step explanation:
First of all, we need to identify the equation of the line. x and y intercepts are known, so we can quickly write the line as
That gives us the last two options. To solve it let's plug a convenient point - read: the origin - into the equation and see which one holds true. And since for obvious reason 
the valid solution is the last one.
Answer:
By distance formula ,
(approx)
To give answer in 3 significant figures :
AB = 6.70
Answer:
61
Step-by-step explanation:
hi! we can start off by plugging in the number 9 for x in the equation.
f(x)=8x-11)
f(9)= 8(9)-11
= 72-11
=61
hope this helps.
