If you already have six but need 34 you would subtract 6 from 34 to get the amount if money you still need. 34-6=28 so you would need 28 more dollars to get to 34 dollars

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y - 3x = 1

2y - x = 12

Step 2: Rewrite Systems

y - 3x = 1

Add 3x on both sides: y = 3x + 1

Step 3: Redefine Systems

y = 3x + 1

2y - x = 12

Step 4: Solve for x

Substitution

Substitute in y: 2(3x + 1) - x = 12
Distribute 2: 6x + 2 - x = 12
Combine like terms: 5x + 2 = 12
Isolate x term: 5x = 10
Isolate x: x = 2

Step 5: Solve for y

Define equation: 2y - x = 12
Substitute in x: 2y - 2 = 12
Isolate y term: 2y = 10
Isolate y: y = 5

Find the domain of the function:

makkiz [27]

Answer: OPTION C.

Step-by-step explanation:

1. The domain of the function given in the problem are all those values for which the function that is in the denomiantor is different from zero, because the division by 0 is not allowed.

2. You can make the denominator equal to zero and solve it, as you can see below:

$x^{3}-2x^{2}+x=0\\x(x^{2}-2x+1)=0\\x(x-1)(x-1)=0\\x=0\\x=1$

3. Therefore, the domain is:

(-∞,0)U(0,1)U(1,∞)

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written

jarptica [38.1K]

Answer:

b) y = f(x) = -3x+4

Step-by-step explanation:

Explanation

Given that the equation 9x+3y =12

Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form

y = f(x)

3 y = 12 - 9x

$y = \frac{-9x+12}{3}$

y = -3x+4

The function represented by y = -3x+4
