You can cross multiply fractions only if there is an "=" sign in the middle of the two fractions.
Y-intercept of f(x) is a value of function for x = 0.
y = 6^x ⇒ f(x) = 6^x
f(0) = 6^0 = 1
Answer: (0; 1)
There are 3 pairs of earrings that you bought in addition to the jeans. Forming an equation with the given values helps to find the required value.
<h3>How to write an equation for the given information?</h3>
It is given that,
A pair of jeans cost = $44
A pair of earrings cost = $12
you spent a total of $80 before taxes.
So, the equation for the given data is,
$80 = $44 + $12x
Where x is the number of pairs of earrings.
<h3>Calculation:</h3>
Simplifying the obtained equation:
$80 = $44 + $12x
⇒ 12x = 80 - 44
⇒ 12x = 36
⇒ x = 36/12
∴ x = 3
Thus, you can buy three pairs of earrings at the mall in addition to the jeans.
