The table shown below shows some values for functions f(x) and g(x). What is/are the solution(s) to f(x)=g(x)? Explain your answ
aleksandr82 [10.1K]

Answer: x = -1 and x = 1

Step-by-step explanation:

The solution to f(x) = g(x) is the point at which the two intersect , that is , the point at which they are equal. Checking through the table given ,it is only 9 and 12 that is common to both f(x) and g(x) .

Therefore : the solution to f(x) = g(x) is the point where x = -1 and x = 1

If x / 2y = 0.4 , A / 5B = 0.25 Then A + y / 5 =….... ​
shusha [124]

Answer:

\frac{x}{2y}  =  \frac{4}{10}  \\ 8y = 10x \\ y =  \frac{10x}{8} -  -  -  -  - 1  \\  \\  \frac{a}{5b}  =  \frac{25}{100}  \\  \frac{a}{5b}  =  \frac{1}{4}  \\ 4a = 5b \\ a =  \frac{5b}{4}  -  -  - 2 \\  \\ so \:  \:  \frac{a + y}{5}  \\  = (a + y) \times  \frac{1}{5}  \\  = ( \frac{5b}{4}  +  \frac{5x}{4} ) \times  \frac{1}{5}  \\  =  \frac{5b + 5x}{4}  \times  \frac{1}{5}  \\  =  \frac{5(b + x)}{4}  \times  \frac{1}{5}  \\  =  \frac{b + x}{4}  \\  \\ so \:  \:  \:  \frac{a + y}{5}  =  \frac{b + x}{4}

I think of a number and add one fourth of it to half of it and the result is twelve. What is the number I thought of?
belka [17]

Suppose that the number u were thinking about is x thus :

\frac{1}{4} x +  \frac{1}{2} x = 12 \\

Multiply both sides by 4

4 \times ( \frac{1}{4} x +  \frac{1}{2} x) = 4 \times 12 \\

x + 2x = 48

3x = 48

Divide both sides by 3

\frac{3x}{3}  =  \frac{48}{3  }  \\

x = 16
