Answer:

$f(3) =-8$

Step-by-step explanation:

Given

$f(x) = 2x + 5; x$

$f(x) =-3x + 1; x >1$

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

$f(x) =-3x + 1$

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

$f(3) =-3*3 + 1$

$f(3) =-9 + 1$

$f(3) =-8$

How do I solve for x

skad [1K]

Answer:

Step-by-step explanation:

Look at the picture.

If ABC is any triangle and AD bisects (cuts in half) the angle BAC, then

$\dfrac{AB}{BD}=\dfrac{AC}{DC}$

In our triangle we have the proportion:

$\dfrac{x}{8}=\dfrac{10-x}{6}$ <em>cross multiply</em>

$6x=8(10-x)$ <em>use distributive property</em>

$6x=(8)(10)+(8)(-x)$

$6x=80-8x$ <em>add 8x to both sides</em>

$14x=80$ <em>divide both sides by 14</em>

$x=\dfrac{80}{14}$

$\boxed{x=\dfrac{40}{7}}$

Compute the odds in favor of obtaining a number divisible by 5 in a single roll of a die.

Georgia [21]

Answer:

1/6 or 16.7% chance

Step-by-step explanation:

A die has 6 sides, and there is only one side with a number divisible by 5, which is the number 5.

So, the probability of rolling a number divisible by 5 is 1/6.

= 1/6 or 0.167
