f(x, y) = 4x + 7y - 6
substitute x=5 and y=-5
f(5,-5) = 4(5) + 7(-5) - 6
f(5,-5) =20-35-6
= -15-6
=-21
x=-5
what does y equal to
Hello.
X= −5/14 y
Step 1: Add -15x to both sides.
x−5y+ −15x= 15x+ −15x
−14x−5y=0
Step 2: Add 5y to both sides.
−14x −5y+5y= 0+5y
−14x=5y
Step 3: Divide both sides by -14.
−14x/−14= 5y/−14
x= −5/14 y
Have a nice day
Hi there!
To convert a fraction to a percentage you need to first convert the fraction to a decimal number. To convert a fraction to a decimal number you need to treat the fraction like a division problem.
as a division problem would be 1 divided by 3, which is:
1 ÷ 3 = 0.3333333...
Now to covert a decimal to a percent all you do is move the decimal point over to the hundreds place, so it will look like this:
33.3
I will be rounded down because it is less then 5. Now just add a percent sign on the end and that is your answer! I should look like this:
33.3%
