A. X=2
Combine like terms 9=-7+8x
Add 7 to both sides 16=8x
Divide 8 from both sides x=2

9 = -7 + 8x
add 7
16 = 8x
x = 2

I'm assuming your allowed to use a calculator for this? That's what I would do.
$\sqrt{108} = 10.39$
To go about the fraction, take the whole number and times it by the denominator, then add in the numerator to create a new fraction(a whole one not mixed). Then simply divide the numerator by the denominator.
$9 \times 20 = 180$
$180 + 13 = 193$
193 is the new numerator and the new whole fraction is this and dividing it out gives you,
$\frac{193}{20} = 9.65$
For the third one, just input it into a calculator,
$2\pi + 3.4 = 9.68$

I NEED HELP ASAP PLEASE

Ahat [919]

Answer: Domain: 0,1,2,3 and 4 and Range: 1,2,4,8 and 4

Step-by-step explanation:

The domain is the set of all inputs that makes the function definable. As we see the function looks like an exponential function which means the domain is all real numbers.

So the inputs are 0,1,2,3 and 4

the outputs are 1,2,4,8 and 4

If n = 5 and r = 3 Find "Cr.

Marat540 [252]

Answer:

Cr = 10

Step-by-step explanation:

To calculate combinations we use the nCr formula: nCr = n! / r! * (n - r)!, where n = number of items, and r = number of items being chosen at a time.

$C(n,r)=[?]$

$C(n,r)=C(5,3)$

$=\frac{5}{(3!(5-3)!)}$

$=\frac{5!}{3!*2!}$

$=10$
