Answer:
Since one equation already has one variable isolated(x), it gives you a "value" to input into the other equation to use to solve for the other variable(y).
10(y-3) + 10y = 1
10y - 30 + 10y = 1
20y - 30 = 1
20y = 31
y = 31/20 or 1.55
Now you can use this value to solve for x in one of the original equations.
x = (31/20) - 3
x = -29/30 or -1.45
Hope this helps!
Step-by-step explanation:
Answer:
f(x) is another way of saying y.
360-9x=y
You would then graph the equations and list the ordered pairs that line crosses on the x-axis and the y-axis.
Step-by-step explanation:
144/145
Convert any mixed numbers to fractions
Then your initial equation becomes
48/5 divided by 29/3
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis.
According to the data of the statement we have the following points:
We found the slope:
Thus, the equation is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
48/12 = 24•2/6•2= 24/6= 12•2/3•2= 12/3= 4/1
In simplest form the ratio is
