Answer:
y = 4 (-3) - 2
y = -12 - 2
y = -14
Step-by-step explanation:
Hello!
First of all you look at how many X's the line moves by, in this case it is -3
Then you look at how many y's the line moves by, in this case it is -2
Then you add together the number of X's moved and the number of y's moved:
-3x + -2y
( adding a negative number is the same as subtracting that number)
thus the answer is A. -3x-2y
Hope This helps! :)
Answer:
Step-by-step explanation:
l=√(4²+7²)
=√(16+49)
=√(65)
≈8.1 ft
wall is perpendicular to base and ladder is hypotenuse.
applying pythagoras's theorem.
First,you do,2/5+2/3,but since you will need a common denominator,you will find the least common denominator for 5 and 3.The LCD(Least Common Denominator) will be 15 since both 5 and 3 could go in 15.Now,the equation looks like this: 2/15+2/15 since whatever you do to the bottom numbers,you NEED to do to the top numbers:2 and 2.Now you will need to do,2x3,since 5x3=15 and the answer to 2x3=6 then you do 2x5,since 3x5=15 the answer is 10 now the equation looks like this:6/15+10/15 now you add them together,and the answer will be 16/15 and if you want the answer to be a mixed number,it would look like this: 1 1/15. Hope this helps!
