3x=5x-9 pls help ?!!?!?!?!?!?!?!?!??!!?1/
lbvjy [14]

Answer: x = 4.5

Step-by-step explanation:

1) Reorder the terms:

3x = -9 + 5x

2) Solving

3x = -9 + 5x

3) Solving for variable 'x'.

4) Move all terms containing x to the left, all other terms to the right.

5) Add '-5x' to each side of the equation.

3x + -5x = -9 + 5x + -5x

6) Combine like terms: 3x + -5x = -2x

-2x = -9 + 5x + -5x

7) Combine like terms: 5x + -5x = 0

-2x = -9 + 0

-2x = -9

8) Divide each side by '-2'.

x = 4.5

9) Simplifying

x = 4.5

Paige works at a department store and has a commission rate of 3 percent. Her sales for the quarter were $4,596. If she earns $5
vagabundo [1.1K]
If she gets 3% of what she sells you multiply the decimal form of the percent by the amount she has made:
50*.03=1.5
So she make $1.50 for every $50 of sales, so you multiply the amount she made by her commission each day by the number of days she worked:
1.5*30=45
 
She earned a total of $45<span />

For for each quadratic function below use method of completing the Square or averaging the x-intercept to write the equation in
lions [1.4K]

We have the expressions:

f(x)=x^2+6x+15y=x^2-4x+9f(x)=x^2-8xy=x^2+7x-2

Now, with this we operate as follows:

a)

f(x)=x^2+6x+15=x^2+6x+9+15-9\Rightarrow(x+3)^2+6

Then, the axis is x = -3 and the vertex (-3, 6)

b)

y=x^2-4x+9=x^2-4x+4+9-4\Rightarrow(x-2)^2+5

Then, the vertex is (2, 5) and the axis is x = 2.

c)

f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4

Then, the vertex is (2, -4) andd the axis is x = 2.

d)

y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}

Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
