Question (1):

Price last week = $6.00
Price this week = $7.20

Increased = $7.20 - $6.00 = $1.20

Answer : Percentage increased = $1.20/$6.00 x 100 = 20%

Question (2):

Original Price = $90

Marked down = 35% of $90 = 0.35 x 90 = $31.50

Price after marked down = $90 - $31.50 = $58.50

Answer: Lilly will pay $58.50 for the football cleats.

A system of equations is given below. For what value(s) of x is f(x)=g(x) ?
NARA [144]

\large{f(x) = g(x)}   \\  \large{ {x}^{2}  + 3x = x + 3}

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

\large{  {x}^{2}  + 3x - x - 3 = 0}

Combine like terms.

\large{ {x}^{2}  + 2x - 3 = 0}

Solve the equation by factoring.

\large{(x  + 3)(x - 1) = 0} \\  \large{x =  - 3,1}

Hence the values of x that make f(x) = g(x) are -3 and 1.

Answer

  • x = -3,1

Let me know if you have any doubts!
