Answer:
y = -7
Step-by-step explanation:
If x equals -14 then you would plug it in and the equation would be -2(-14)-3y=49
The new equation would be 28-3y=49
Then you would subtract 28 from both sides and get -3y=21
Lastly you would divide both sides by -3 and get y=-7
5 Is the square root of 125
You would use 1.73 in order to decrease an amount by 73%
The answer is 4.5.
The formula for a rectangle is A = lw. Substitute the formula, so it'll be 27 = (2x - 3) * x. Evaluate the formula.
Hope this helps you! And rate me to see if I did it right. Thanks!
Let them be X and Y..
now...
yx=100 ....
y=100/y ...
now...
x+y= s....where s is their sum...
but y=100/x
now....x+100/x=s..
by differentiating both sides with respect to x..
1-100/x^2=ds/dx
but ds/dx=0..
100=x^2 ..
x=10..
so y=10
