Answer:

See below

Step-by-step explanation:

$p=2i-j$

$q=-i+j$

$p+q=(2i-j)+(-i+j)=2i-j-i+j=i$

$p-q=(2i-j)-(-i+j)=2i-j+i-j=3i-2j$

$2p-3q=2(2i-j)-3(-i+j)=4i-2j+3i-3j=7i-5j$

Let f (x) = 1/x<br> and g(x) = x² – 3x. What<br> two numbers are not in the domain of fºg?

iren [92.7K]

For this case we have the following equations:

$f (x) = \frac {1} {x}\\g (x) = x ^ 2-3x$

We must find $(f_ {o} g) (x):$

By definition of composition of functions we have to:

$(f_ {o} g) (x) = f (g (x))$

So:

$(f_ {o} g) (x) = \frac {1} {x ^ 2-3x}$

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

$x ^ 2-3x = 0\\x (x-3) = 0$

So, the roots are:

$x_ {1} = 0\\x_ {2} = 3$

The domain is given by all real numbers except 0 and 3.

Answer:

x other than 0 and 3

Help ASAP!!!!<br> Which statement about the graph of the function y=(1/3)x are true?

mafiozo [28]

Answer:

Step-by-step explanation:

1) False: The function is decreasing (because the base, 1/3, is between 0 and 1).

2) True: The function is decreasing (see #1, above)

3) False: There is no x-intercept.

4) True: If x is 0, then y = (1/3)^0 = 1.

5) False: the range consists of the set of all real numbers greater than zero.

Px^2-qx+r=0 solve by complete squaring method

Natasha2012 [34]

Step-by-step explanation:

px^2-qx+r

p(x^2-q/px)+r

p[(x^2-q/px +(q/2p)^2_(q/2p)^2)]+r

p[(x-q/2p)^2 -q^2/4p^2)]+r

p(x-q/2p)^2 -q^/4p+r

p(x-q/2p)^2-(q^2-4pr)/4p

Claudia is making a gelatin dessert for a party. She plans on making 12 servings for every 5 people. If each pan Claudia uses to

just olya [345]

Answer:

Step-by-step explanation:

Key Word: 12 servings for every 5 people. if she makes it to hold 8 servings, what is enough plans she needs to feed 10 people?

formula: so 12 for 5 then 24 for 10.

solving problem:

12 people over 5 people = x over 10 people

since 5 times 2 equals 10 then 12 times is 24.. so we need 24 servings

we know from reading the question that each pan makes 8 servings.

$\frac{24}{8} = 3$
