Evaluate 6+ the sq root of 14+x minus - the sq root of 9x when x=2

romanna [79]

Hello
let : f(x) = 6 + √(14+x) - <span>√(9x)
f(2) = </span>6 + √(14+2) - √(9×2)
f(2) = 6 + √(16)-√(18)
f(2) = 6 + 4 - √(18) = 10 - √(18)

Graph the line. y = -5x + 1

gizmo_the_mogwai [7]

Answer:

See below.

Step-by-step explanation:

To graph y = -5x + 1 we must move 1 unit up and 5 units down plus a unit to the right

Since the slope is negative, therefore, we move down 5 units

Since the y-intercept is positive 1 then we move 1 unit up

Important Note: Start by the y-intercept first, then the slope

There are 6 people in a raffle drawing, Two raffle winners each win gift cards,

Tju [1.3M]

Answer:

B. Combination: Number of ways = 15

Step-by-step explanation:

2 winners are to be chosen out of 6 people participating in the raffle drawing. In this case the order of selection does not matter, therefore, this situation involves combinations

So, we have to find combinations of 6 people taken 2 at a time. This can be represented by 6C2. The general formula for combinations is:

$^{n}C_{r}=\frac{n!}{r!(n-r)!}$

In this case n = 6 and r = 2. Using these values, we get:

$^{6}C_{2}=\frac{6!}{2! \times (6-2)!} \\\\ ^{6}C_{2}= \frac{6!}{2! \times 4!}\\\\ ^{6}C_{2}=\frac{6 \times 5 \times 4!}{2 \times 4!}\\\\ ^{6}C_{2}= \frac{30}{2}\\\\ ^{6}C_{2}= 15$

Thus, there are 15 ways to chose the winners. So, option B gives the correct answer.
