problem → 2^x = 4, solve for x
⇒2^x=4
⇒2^x=2^2
⇒x=2
Answer:
El precio de la falda es 50 €.
Step-by-step explanation:
Lo que sabemos:
(1)
En donde F es por falda y B por blusa.
Si compras 6 faldas y 4 blusas y pagas 480 €:
(2)
Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.
Finalmente, el precio de la falda se puede encontar con la ecuación (1):

Answer:
Step-by-step explanation:
<u>Find zeros first:</u>
- x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
- x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)
<u>We have 4 intervals:</u>
- x ≤ - 3, three negatives, the result is negative or zero
- -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
- 2 ≤ x < 7, two positives and one negative, the result is negative or zero
- x > 7, three positives, the result is positive or zero
<u>The solution is:</u>
Correct choice is A
