(4x + 10) – (-3x + 5) <br> Help
dalvyx [7]

Answer:

x= -15 or (7x+5)

Step-by-step explanation:

Simplifying

4x + 10 = 3x + -5

Reorder the terms:

10 + 4x = 3x + -5

Reorder the terms:

10 + 4x = -5 + 3x

Solving

10 + 4x = -5 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

10 + 4x + -3x = -5 + 3x + -3x

Combine like terms: 4x + -3x = 1x

10 + 1x = -5 + 3x + -3x

Combine like terms: 3x + -3x = 0

10 + 1x = -5 + 0

10 + 1x = -5

Add '-10' to each side of the equation.

10 + -10 + 1x = -5 + -10

Combine like terms: 10 + -10 = 0

0 + 1x = -5 + -10

1x = -5 + -10

Combine like terms: -5 + -10 = -15

1x = -15

Divide each side by '1'.

x = -15

Simplifying

x = -15

During a sale at a bookstore, a customer buys one book at full price. The customer is given a 25 percent discount on a second bo
RoseWind [281]
Amount paid for the first book is $17.

Amount paid for the second book is 0.75 x 8 = $6

Total amount paid = $17 + $6 = $23

Total full cost of the two books = $17 + $8 = $25

Amount of discount = $25 - $23 = $2

% reduction = \frac{2}{25} \times100\%=8\%

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%

HELP PLS 99 POINTS
enyata [817]

2x²-2x-12=0
simplify it into x²-x-6=0
factored form: (x-3)(x+2)=0
solutions: x-3=0 or x+2=0
x=3 or x=-2
Not sure how to explain "what the solutions mean for the equation". One thing you can say is that the solutions mean the equations have two roots/two zeros: 3 and -2, or the graph of 2x²-2x-12 intersects the x axis at (3,0) and (-2,0).
