Answer:
or
Step-by-step explanation:
To write the equation of the line using a slope and a point, use the point-slope formula 
. Here m is 3/7. And the point 
is (4,9). Substitute the values and simplify.
Both the point slope form and the final simplified form are considered equations of the line.
The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
Answer:
30 ounces
Step-by-step explanation:
You first have to write out the two equations:
5+0.25x=y
2+0.35x=y
Then simply equal the equations to each other:
5+0.25x=2+0.35x
Subtract the 2 from both sides:
3+0.25x=0.35x
Subtract the 0.25x from both sides:
3=0.10x
Divide the 0.10 on both sides:
30=x
So, 30 ounces is your answer!
You can check by plugging 30 back into the equations to make sure that they are equal to each other.
5+0.25(30)=12.5
2+0.35(30)=12.5
Answer:
y=6.75x
Step-by-step explanation:
he xharges 6.75 per hour, so 6.75x equals the total price, y

Answer: 14400</h3>
Chances are your teacher doesn't want you to enter any commas. You won't type in the dollar sign either.
============================================================
Explanation:
Nice work on selecting the correct equation to set up.
We'll cross multiply to help solve for x.
The idea of cross multiplication is that 
turns into 
So,
That means the person would pay $14,400 on a property worth $800,000.
