Think of it as it being 5 - 1 which equals 4. So you would have four more than her
<span>Area that needs to be painted=1600 sq.ft.
1 gallon of paint covers 250 sq.ft.
Total area for which paint needs to be bought=1600-250 sq.ft=1350 sq.ft. [Since, Mr. Arnold already has 1 gallon of paint]
Total paint that needs to be bought=1350/250=5.4 gallons
Alternatively,
Total paint required=(Area to be painted/Coverage of 1 gallon of paint)-1 [Since, Mr. Arnold already has 1 gallon of paint]
Total paint required= (1600/250)-1 gallons
=6.4-1 gallons=5.4 gallons of paint is required</span>
Answer:
-8
Step-by-step explanation:
So the gradient is the negative reciprocal of the question so first you have to rearrange the equation into the form y = mx + c so you get 3y = - 5 x + 11 and then y = -5/3 x + 11/3. Now to find the gradient of the line perpendicular to it you do the negative reciprocal and get 3/5 x so now you have the equation y = 3/5 x + c . Now simply substitute your coordinate into the equation to get -2 = 3/5 x -2 + c and 3/5 x -2 is -1.2 so now you have 2 = -1.2 + c so c is 3.2 so your final equation is y = 3/5 x + 3.2 hope this helps :)
