Solve the equation for all values of x.<br> (8x+9)(49x^2-100)=0
Liono4ka [1.6K]

Answer:

x = \frac{-9}{8} , \frac{-10}{7} , \frac{10}{7}

Step-by-step explanation:

8x+9=0

8x=-9

x = \frac{-9}{8}

or

49x^{2}-100 = 0

(7x)^{2} -10^{2} =0,

(7x+10)(7x-10)=0

7x+10=0, 7x-10=0

7x=-10, 7x=10

x=-\frac{-10}{7}, x = \frac{10}{7}

If f(x)=2x+3÷2,find f-1(x).​
BartSMP [9]

The required inverse function  f^{-1}(x) = (2x - 3 ) / 4.

Given that,
f(x) = (2x+3) / 2

To find  f^{-1}(x)

<h3>What are functions?</h3>

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Let f(x) = y
y = (2x + 3) / 2
y * 2 = 2x + 3
2y - 3 = 2x
x = (2y - 3) / 2
Now replace y = x and x = f^{-1}(x)
 f^{-1}(x) = (2x - 3 ) / 4


Thus,  the required inverse function  f^{-1}(x) = (2x - 3 ) / 4.
