The equation of a function<br>y = 2/3x+1/3 find the value of y<br>when x = -3<br>when x = 1 1/2

kirill [66]

Answer:

$y = \frac{-5}{3}\\\\y = \frac {4}{3}$

Step-by-step explanation:

$y = \frac{2}{3} x + \frac{1}{3}\\\\when \ x = -3 \\\\y = \frac{2}{3}(-3) + \frac{1}{3} = -2 + \frac{1}{3} = \frac{-6 + 1}{3}= \frac{-5}{3} \\\\When \ x = 1 \frac{1}{2} = \frac{3}{2}\\\\y = \frac{2}{3} \times \frac{3}{2} + \frac{1}{3} = 1+ \frac{1}{3} = \frac{3 + 1}{3}= \frac{4}{3} \\\\$

June father is six times as old as June the sum of their age is no less than 77 what is the youngest age June can be

alexgriva [62]

Let June's age be
$x \: years$

Then his father is
$6x \: years$

The sum of their ages is no less than 77 means,
$x + 6x \geqslant 77$
$7x \geqslant 77$
$x \geqslant 11$
The youngest age June can be is 11
