Answer:
d) 3x + y = 5
Step-by-step explanation:
The standard equation of a line with slope and a point is given by:
y = mx + b
We know that
m=-3
Putting the value of slope
y = -3x+b
To find the value of b, we will put the point in the equation
-1 = (-3)(2)+b
-1 = -6 + b
-1+6 = b
b = 5
Putting the values of b and m in standard equation
y = -3x+5
Can also be written as:
3x+y = 5
Hence,
Option d: 3x + y = 5 is the correct answer ..

Answer:
34.22 liters
Step-by-step explanation:
Step one:
Given data
A car averages 28.5 miles per gallon of gasoline
How many liters of gasoline will be needed for a trip of 415 km
let us convert 415km to miles first
1 km is 0.621371 miles
415km is x miles
cross multiply we have
x= 415*0.621371
x=257.86 miles
Step two:
if 1 gallon of gasoline will cover 28.5 miles
the x gallons will cover 257.86 miles
cross multiply we have
28.5x= 257.86
divide both sides by 28.5
x= 257.86/28.5
x=9.04 gallons
Step three:
let us convert gallons to liters
1 gallon is 3.78541 liters
9.04 gallons will be x liters
cross multiply we have
x=9.04*3.78541
x= 34.22 liters
Answer:
0.17
Step-by-step explanation:
0.017 times 10 will equal to 0.17 as you will need to move the decimal point forward by one
Alright my friend so if she ran 1/4 a mile in just 3 minutes then her overall time will be 12 minutes because she still has 3 more to go so basically it'll be 3 x 4 = 12
