1 1. Find the x-intercepts for y= 2(x - 7)(x+2)?

givi [52]

Answer:

$b.) (7,0) and (-2,0)$

Step-by-step explanation:

To find the x-intercept, substitute 0 for y and solve for x:

$0=2(x-7)$

Divide both sides by 2:

$\frac{0}{2}=\frac{2(x-7)}{2}$

$0=x-7$

Add 7 to both sides to isolate x:

$0+7=x-7+7\\7=x$

The x-intercept for $y=2(x-7)$ is 7 at point $(7,0)$ .

$0=(x+2)$

Remove parentheses:

$0=x+2$

Subtract 2 from both sides:

$0-2=x+2-2$

$-2=x\\x=-2$

The x-intercept for $y=(x+2)$ is -2 at point $(-2,0)$ .

Finito.

You are dealt two cards successively without replacement from a standard deck of 52 playing cards. Find the probability that the

kondaur [170]

Answer:

$\frac{4}{52} \times \frac{4}{51} = \frac{16}{2652} = 0.00603 = 0.603\%$

Step-by-step explanation:

There are 52 cards in a standard deck, and there are 4 suits for each card. Therefore there are 4 twos and 4 tens.

At first we have 52 cards to choose from, and we need to get 1 of the 4 twos, therefore the probability is just

$\frac{4}{52}$

After we've chosen a two, we need to choose one of the 4 tens. But remember that we're now choosing out of a deck of just 51 cards, since one card was removed. Therefore the probability is

$\frac{4}{51}$

Now to get the total probability we need to multiply the two probabilities together

$\frac{4}{52} \times \frac{4}{51} = \frac{16}{2652} = 0.00603 = 0.603\%$

If f(x)= x squared and g(x)=2x^3- x squared, find f(x)-g(x).

tankabanditka [31]

Answer:

$f(x)-g(x)=2x^2(1-x)$

Step-by-step explanation:

Given that,

$f(x)=x^2\\\\g(x)=2x^3-x^2$

We need to find the value of f(x)-g(x).

Put the values of f(x) and g(x). So,

$f(x)-g(x)=x^2-(2x^3-x^2)\\\\=x^2-2x^3+x^2\\\\=2x^2-2x^3\\\\=2x^2(1-x)$

So, the value of f(x)-g(x) is equal to $2x^2(1-x)$ .
