Given:
A line passes through (-5,-3) and perpendicular to 
.
To find:
The equation of the line.
Solution:
We have,
On comparing this equation with slope intercept form, i.e., 
, we get
It means, slope of this line is 
.
Product of slopes of two perpendicular lines is always -1.
Slope of required line is 
and it passes through the point (-5,-3). So, the equation of the line is
where, m is slope.
Therefore, the equation of required line is 
.
Sorry but where is the picture? I’m confused..
Step-by-step explanation:
a) determine the rate in km/L
==> 9.5 L/100km = 10.526316 km/L
b) how far can the car travel with 475L petrol
==> 0.210526315789473km/l
c) how many litres of petrol do they need to travel 350 km
==>Liters per km (l/km)2.86×10-3
Liters per 10 km (l/10 km)0.03
Liters per 100 km (l/100km)0.29
Kilometer per liter (km/l)350
Answer:
-14/15
Step-by-step explanation:
First, you want to turn each mixed number into an improper fraction. So you get -10/3 + 12/5. Then you want to get the same denominator, and the LCD happens to be 15. You get -50/15 + 36/15. Addition is commutative, so you can do something like this: 36/15 - 50/15. You can do 36-50=-14, and then add the denominator to get -14/15.
I think It's 0.9% I'm not sure though or 1.03%
