Step-by-step explanation:
use what u learned
Y=1x+(-5) because the y-intercept is negative 5 and that is going to be the B value. Because anything that multiplies with zero equals zero so when you input 0 for x the b value would always be the y-intercept.
The denominator of the rational expression 600/(x-4) is x-4.
We know x represents Sarah’s average speed. So x-4 will also represents the average speed. And x-4 represents 4 mph less than the average speed of Sarah, x.
Therefore, option a) is correct.
