Answer:

False

Step-by-step explanation:

4x+4+5y=9xy+4

Step 1: Add -9xy to both sides.

4x+5y+4+−9xy=9xy+4+−9xy

−9xy+4x+5y+4=4

Step 2: Add -5y to both sides.

−9xy+4x+5y+4+−5y=4+−5y

−9xy+4x+4=−5y+4

Step 3: Add -4 to both sides.

−9xy+4x+4+−4=−5y+4+−4

−9xy+4x=−5y

Step 4: Factor out variable x.

x(−9y+4)=−5y

Step 5: Divide both sides by -9y+4.

x(−9y+4)

−9y+4

−5y

−9y+4

−5y

−9y+4

Answer:

−5y

−9y+4

this does not add up as in um.. i forgot the word- but yea its false

Answer:

Cups of carrot needed for 9 servings = 4.5 cups

Step-by-step explanation:

A recipe for sesame chicken calls for cup of chopped carrots

recipe 2 is for 4 servings

That is

2 cups of carrot = 4 servings

2 : 4

= 1 : 2

1 cup of carrot = 2 servings

how many cups of

carrots are needed for 9 servings?

Let x= number of carrot needed for 9 servings

1 : 2 = x : 9

1 /2 = x/ 9

Cross product

1*9 = 2*x

9=2x

Divide both sides by 2

9/2 = x

x= 4.5 Or 4 1/2

Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it

Answer:

$t+0.07t=t(1+0.07)=t(1.07)=1.07t$

Step-by-step explanation:

There are a couple of equivalent expressions to the function $t+0.07t$ . For example:

$t+0.07t$

Factor:

$t+0.07t=t(1+0.07)$

If you add the terms inside the parentheses:

$t(1+0.07)=t(1.07)$

Basically you can add the like terms from the start and get the same result.

$t+0.07t=1.07t$

Therefore:

$t+0.07t=t(1+0.07)=t(1.07)=1.07t$
