Answer:
≈ 7 hours
Step-by-step explanation:
Maria can do full job in 13 hours,
she can do 1/13 part of job in one hour
Felipe can do full job in 15 hours,
he can do 1/15 part of job in 1 hour
Together they can do:
- 1/13 + 1/15= 28/13*15= 28/195 of job in 1 hour
to complete full job they need:
- 1 ÷ 28/195= 195/28 ≈ 7 hours
If we then plug in the slope<span> and y intercept into the slope-intercept formula of </span><span>y=mb+b</span><span> where </span><span>m=</span><span> the slope the </span><span>b=</span><span> the y intercept, then </span>
<span>y=mx+b</span><span> becomes</span>
<span>y=0x+<span>(−2)</span></span><span> which simplifies to </span><span>y=−<span>2
