The gradient of the perpendicular line would be the negative reciprocal of the original line. Therefore the gradient of the perpendicular line would be -2/5x.
Since we know y=mx+c, ∴y=-2/5x+c. Sub in the x and y values of the given point and we get that c=26/5.
The perpendicular equation would be y=-2/5x+26/5.
I hope I got this right.
Answer:
7.5 kilograms of apples
Step-by-step explanation:
Take the total amount and subtract the amount of pears.
8.9-1.4=7.5
4.5 hrs because 162.50-50 = 112.50
112.50/25= 4.5
Answer:
Find how much she will be paid per mile to make it easier.
.25 * 4 = 1
.90 * 4 = 3.60
Now you know she earns 3.60 per mile, multiply that by 7.
3.60 * 7 = $25.20 total.
3 miles = 5,280 yards
6(250) = 1,500 yards
5,280 - 1,500 = 3,780 yards
