Marissa bought a skirt on sale for $8.45 less that 60% off the original price. She paid $9.55 for the skirt. What was the origin

nadya68 [22]

Answer:

$23.88

Step-by-step explanation:

Represent the original price by p.

The sale price is (100% - 60%), or 40%, of p:

$9.55 = 0.40p

Dividing both sides by 0.40 results in:

p = $23.88 (rounded up from $23.875).

F(x) = -7x2 + 9x - 15 and g(x) = -12x2 – 15x + 7

djyliett [7]

Answer:

${5x}^{2} + 6x = - 8$

Step-by-step explanation:

This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.

${ - 12x}^{2} - 15x + 7 - ({ - 7)x}^{2} + 9x - 15$

Now we can solve for the equation.

${ - 5x}^{2} - 6x - 8 = 0 \\ {5x}^{2} + 6x = - 8$
