If f(x) varies directly with x and f(x) = 4 when x = 12, then what is the value of f(x) when x = 60?

ANTONII [103]

ANSWER

$f(60)=3\times60=180$

EXPLANATION
We were given that
$f(x)$
varies directly as
$x.$

We can write this mathematically as,

$f(x) \propto \: x.$

This implies that,

$f(x) = kx$
where k is the constant of variation.

$f(4)=4k$

This implies that,

$4k=12$

$k = 3$

The equation becomes

$f(x)=3x$

When $x=60$

$f(60)=3\times60=180$

Two consecutive integers have a sum of 153. find the integers.

Natasha2012 [34]

X = first integer
x + 1 = second consecutive integer

x + (x + 1) = 153..combine like terms
2x + 1 = 153
2x = 153 - 1
2x = 152
x = 152/2
x = 76

x + 1 = 76 + 1 = 77

so ur numbers are : 76 and 77...and u will find that when added equal 153.
