If y varies directly with x, and y = 18 when x = 4, what is the constant of proportionality?
GREYUIT [131]
Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.

Dividing both sides by x for the given values, k becomes 18/4 = 4.5

Solve the simultaneous equations by substitution 3 x − 7 y = − 10 x = 5 y + 2
mojhsa [17]

Answer:

3x-7y=-10_{(1)} \\x=5y+2_{(2)}\\

Substituting Equation 2 into equation 1

3(5y+2)-7y=-10_{(3)} \\15y+6-7y=-10\\15y-7y+6=-10\\8y+6=-10\\8y=-10-6\\8y=-16\\y=\frac{-16}{8} \\y=-2\\

Substitute the value of y into Equation 2

x=5y+2\\x=5(-2)+2\\x=-10+2\\x=-8\\

Therefore x=-8, y=-2

Given the function f(x) = x^3 + x^2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?
Vikki [24]
The resulting function g(x) is ...
  g(x) = f(x +1)
  g(x) = (((x +1) +1)(x +1) -2)(x +1) +1
    = ((x +2)(x +1) -2)(x +1) +1
    = (x² +3x)(x +1) +1
    = x³ +4x² +3x +1

The shifted function g(x) is ...
  g(x) = x³ +4x² +3x +1
