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).
