Write the equation of the line with a slope of 1/5 that passes through the point (20,5)
1 answer:
Answer:
Step-by-step explanation:
the general equation of a line is y=mx+c
because the slop is 1/5, the equation of this line would be
with the coordinates (20,5) , take 20=x and 5=y
and substitute these values into the equation above.
you should get:
5= 4 + c
so c = 1
therefore, the equation of the line is:

The inputs are 1 and -1 when the output is 2.
Step-by-step explanation:
The given function is
f(x) = 10 x²
Then we set y = f (x)
y = 10 x²
By dividing each side by 10 we get
x² = y/10
Then we solve for x
x = ±
Now we have to find the input(s) when the output is 10
x = ±
x = ± 1
Hence, the inputs are 1 and -1 when the output is 2.
The final solution is x =1 and x = -1.
