Answer:

Step-by-step explanation:

The distance is found by

d =sqrt ( (x2-x1)^2 + (y2-y1)^2)

= sqrt( ( 7-7)^2 +(3 - -8)^2)

= sqrt(0 +(3+8)^2)

= sqrt( 11^2)

= 11

What is the value of f(3) in the function f(x)=5/6x+8

natita [175]

For this case we have a function of the form $y = f (x)$ , where $f (x) = \frac {5} {6} x + 8$

We must find the value of the function when $x = 3$ , that is, we must find f (3). So:

$f (3) = \frac {5} {6} (3) + 8\\f (3) = \frac {15} {6} +8\\f (3) = \frac {5} {2} +8\\f (3) = 2.5 + 8\\f (3) = 10.5$

So $f (3) = 10.5$

Answer:

$f (3) = 10.5$

Answer: 84

<u>Step-by-step explanation:</u>

Set up a proportion as follows: $\dfrac{\text{students that practice everyday}}{\text{total students}}$

$\dfrac{7}{12}=\dfrac{x}{144}$

Cross multiply: 12x = 7 × 144

Divide by 12: x = 7 × 12

Simplify: x = 84
