3x+15^2+10= -2
3x+225+10= -2
3x+235= -2
Divide both sides by 3
x+235=0.67
Subtract 235 from both sides
x= -234.33
Sorry, in advance, if I did it wrong.
Answer:
The pre-image C is (2, 5)
Step-by-step explanation:
- If the point (x, y) rotated about the origin by angle 90° clockwise, then its image is (y, -x)
- If the point (x, y) rotated about the origin by angle 180° clockwise, then its image is (-x, -y)
- If the point (x, y) rotated about the origin by angle 270° clockwise, then its image is (-y, x)
∵ Point C was rotated 270° clockwise around the origin
∵ C' = (-5, 2)
→ By using the 3rd rule above
∵ The image of the point (x, y) is (-y, x)
∴ (-y, x) = (-5, 2)
→ That means -y = -5 and x = 2
∴ x = 2
∴ -y = -5
→ Divide both sides by -1
∴ y = 5
∴ The pre-image C = (2, 5)
Answer:
La base salarial de cada trabajador es de $ 425
Step-by-step explanation:
Aquí queremos calcular la base salarial de cada trabajador
Antes del incremento, sea la base salarial $ x
Entonces, sin el incremento, lo que ganarán los 3 es x + x + x = 3x
Con el incremento, cada uno ganará 3 (x + 50)
Esto es lo que es igual a 1425 Así; 3 (x + 50) = 1425
x + 50 = 1425/3
x + 50 = 475
x = 475 - 50
x = 425
Answer:
Value = $15,000 * (.87) ^ Years
After 4 years, .87 ^ 4 = 0.57289761
Value = $15,000 * 0.57289761 =
8,593.46
