Answer:
(3,6)
Step-by-step explanation:
-2x+3y=12
Let x = 3
-2(3) +3y = 12
-6+3y = 12
Add 6 to each side
-6+6 +3y = 12+6
3y = 18
Divide each side by 3
3y/3 = 18/3
y = 6
Answer: Su salario regular por hora es $12
Step-by-step explanation:
Hola, para resolver este problema debemos plantear una ecuación:
A el hombre le pagan doble el tiempo que trabaja por encima de las 40 horas, el trabajo 47, o lo que es equivalente = 40+7.
Las primeras 40 horas recibió su salario regular por hora (x) y las otras 7 recibió el doble (2x). LA suma de esos productos da un total de $648.
Matemáticamente hablando:
40 x+ 7 (2x) = 648
Resolviendo para x (salario regular por hora)
40x +14x =648
54x =648
x = 648/54
x = 12
Answer:
{-9.5, 1,7}
Step-by-step explanation:
For y =f(x)
domain is list of all values of x and range is list of all values of y
Given
ƒ(x) = 3x – 5
domain = {–1.5, 2, 4}.
thus,
range will be value of f(x)
when x = -1.5
x = 2 and x = 4
Thus,
for x = -1.5
ƒ(x) = 3*-1.5 – 5 = -4.5 - 5 = -9.5
\
for x = 2
ƒ(x) = 3*2– 5 = 6 - 5 = 1
for x = 4
ƒ(x) = 3*4– 5 = 12 - 5 = 7
thus,
range of ƒ(x) = 3x – 5 is {-9.5, 1,7}

Answer:
x1 = 0.52
x2 = -10.1
x3 = 0.97
Step-by-step explanation:
From the question;
x1 = 1 - 3/(x0)^2
x0 = -2.5
x1 = 1- 3/(-2.5)^2
x1 = 1 -0.48
x1 = 0.52
x2 = 1 - 3/(x1)^2
x2 = 1 - 3/0.52^2
x2 = 1 - 11.1
x2 = -10.1
x3 = 1 - 3/(x2)^2
x3 = 1- 3/(-10.1)^2
x3 = 0.97
