Wilda can do the job in 4 hours ... she does 1/4 (or 0.25) of it each hour.
Karla can do it in 5 hours ... she does 1/5 (or 0.2) of it each hour.
Wilda worked alone for 1 hour ... 0.25 of the job was done before her helper
arrived. So only 0.75 of the job remained to be done together.
Working together, they accomplish (0.25 + 0.2) = 0.45 of the job in 1 hour.
How many times do they need to do 0.45 of the job in order to finish
the 0.75 of it that remains ? That's the number of hours it will take them,
working together.
0.75 / 0.45 = <em>1 and 2/3</em>
After Wilda worked alone for 1 hour and Karla came along to join her, it will
take them another <em>1 hour and 40 minutes</em> to finish the job and go for a swim.
Ketika dua garis tegak lurus, kemiringan satu adalah timbal balik negatif dari yang lain.Jika kemiringan satu baris adalah m, kemiringan yang lain adalahCoba ini Drag poin C atau D. Catatan lereng ketika garis tegak lurus satu sama lain.
Ketika dua garis tegak lurus satu sama lain (di sudut kanan atau 90 °), lereng mereka memiliki hubungan khusus satu sama lain. Jika kemiringan satu baris adalah m maka kemiringan garis lainnya adalah timbal balik negatif m.
Y = mx + b
m = slope, b = y intercept
Plug in the values
Solution: y = -2x + 3

Step-by-step explanation:
√(x₂ - x₁)² + (y₂ - y₁)²
√(3/2 - 5/2)² + (8 - 3)²
√(-1)² + (5)²
√1 + 25
√26
