Answer:
y+2= -1/5(x+1)
Step-by-step explanation:
if lines are perpendicular their slopes are negative reciprocal
y=mx+b where m is the slope
y=5x-10 has the slope 5 so a perpendicular line will have slope -1/5
equation point slope form
(y-y1) = m(x-x1) where m is slope, and (x1,y1) any point that belongs to the line
y+2= -1/5(x+1)
Answer:
7
Step-by-step explanation:
16x-80+18=4x+22
16x-62=4x+22
12x-62=22
12x=84
x=7
Answer:
18 lawns
Step-by-step explanation:
Expected sum = $515
Bonus for 1 day = $15
Bonus for 5 days = $15 × 5 = $75
Amount to be earned from mowing lawns in 5 days = $515 - $75 = $440
$25 ≡ 1 lawn
$440 ≡ 440 ÷ 25 = 17.6
The minimum number of lawns is 18.
<em>(Note that we take the minimum integer greater than 17.6. If he mows 17 lawns, his earning from 17 lawns = $425 + $75 = $500)</em>
Answer:
y - 10 = -7(x + 6)

Answer:
464 pesos
Step-by-step explanation:
290 / 50 = 5.8
5.8 X 80 = 464
