2/3x - 4 = -2<br><br> please reply as soon as possible!
Xelga [282]

Answer:

x = 1/3

Step-by-step explanation:

Isolate the variable.

2/3x - 4 = -2

Add 4 to both sides.

2/3x = 2

Multiply everything by 3x.

2 = 6x

Divide both sides by 6.

x = 2/6 or 1/3

arsen [322]
Recipe 1 : 4 cups oj with 6 cups pineapple.....ratio of 4/6 reduces to 2/3

recipe 2 : 6 cups oj with 9 cups pineapple...ratio 6/9 reduces to 2/3

recipe 3 : 9 cups oj with 12 cups pineapple....ratio 9/12 reduces to 3/4

so recipe 1 and recipe 2 will taste the same because the ratios are the same...and recipe 3 will be the different tasting one because it has a different ratio mixture

F(x)=3 over x+2-x-3 squared what is f(7)
dimaraw [331]

<u>Answer:</u>

f(7)=\frac{-5}{3} or f(7)=-1.67

<u>Step-by-step explanation:</u>

We are given the following function of x and we are to find the value of f ( 7 ):

f ( x ) = \frac { 3 } { x + 2 } - \sqrt { x - 3 }

Substituting the given value (7) in the above function to get:

f(x)=\frac{3}{x+2}-\sqrt{x-3}

f ( 7 )= \ frac{3}{7+2}-\sqrt{7-3}

f(7) = \frac { 3 } { 9 } - \sqrt { 4 }

f(7)=\frac{1}{3}-2

f(7)=\frac{1}{3}-\frac{6}{3}

f(7)=\frac{-5}{3} or f(7)=-1.67
