A zero or a root is determined at the point where the curve cuts or meets the x-axis or horizontal axis.
To simplify the fraction, convert the decimal to fractional notation, by looking at the place value of the number.
Here 0.5 = 1/2.
And to convert to percentage simply multiply by 100.
Thus it would be 50 percent.
She will earn 50 dollars.
Cross multiply 3 times 125 and multiply 25 times x and you should get 375 equals 25x and then divide 375 and 25 and get
x=15
Add the exponents since it’s multiplication, so it would be 2a^7, hope this helps
