(-3,y), (-9,-2); m=1

Answer:

The value of y is 4

The equation of line is y = x + 7 .

Step-by-step explanation:

Given as :

The points are

( $x_1$ , $y_1$ ) = (- 3, y)

( $x_2$ , $y_2$ ) = (- 9, -2)

The slope = m = 1

Now, The slope is calculated in points form

So, Slope = $\dfrac{y_2-y_1}{x_2-x_1}$

I.e m = $\dfrac{y_2-y_1}{x_2-x_1}$

or, 1 = $\dfrac{- 2 - y}{- 9- (-3)}$

or, 1 = $\dfrac{- 2 - y}{- 6}$

or, 1 × (-6) = - 2 - y

or, - 6 = - 2- y

or, y = - 2 + 6

∴ y = 4

So, The new points as

( $x_1$ , $y_1$ ) = (- 3, 4 )

( $x_2$ , $y_2$ ) = (- 9, -2)

So, the equation of line in slope - point form can be written as

y - $y_1$ = m ( x - $x_1$ )

i.e y - 4 = ( 1 ) × ( x - (-3) )

or, y - 4 = x + 3

∴ y = x + 3 + 4

Or, y = x + 7

So, The equation of line is y = x + 7

Hence The value of y is 4

And The equation of line is y = x + 7 . Answer

Which is true about the expression 3 square root x 2 square root

dexar [7]

Answer:

Step-by-step explanation:

Neither one of the two given numbers are rational. sqrt(3)*sqrt(2) equals the square root of 6. All three numbers are irrational.

You can try it for yourself.

sqrt(2) = 1.4142

sqrt(3) = 1.732

1.4142 * 1.732 = 2.4493

sqrt(6) = 2.4493

The difference is a rounding error.

So the answer is B. sqrt(6) is totally irrational.

(d) Let p represent the probability of a successful long hit. What values of p will make the long hit better than the short hit

seropon [69]

Answer:

The probability of successful long hit is greater than 0.7083

Step-by-step explanation:

Solution

The expected value for long hit is given below

P (successful hit) * 4.2 + P (Unsuccessful hit) *5.4

so,

= P * 4.2 + (1-p) * 5.4

= 5.4 - 1.2p

Now,

If the expected value of long hit is less than that of the short it

Then,

5.4 - 1.2p <4.55

P> (5.4 - 4.55)/1.2

P> 0.7083

Therefore the probability of successful long hit is greater than 0.7083

Note:

Due to my research and findings to this example, the complete question for is attached below, i solved or Question 2(d) only

Solve by factoring: 5x^2 + 19x + 12 = 0

Mariulka [41]

When solving polynomial equations, first set the equation

equal to zero, then check for a Greatest Common Factor.

Since there is no greatest common factor, this will make life a

little bit more difficult because we will have to factor the trinomial.

First, find all possible factors for constant term.

I have listed these in red below.

Make sure to reverse the factors since in each binomial,

the first term is different so we need to reverse the factors.

The factors of 5x² will just be 5x and z.

After finding factors for the constant and the leading

coefficient for your trinomial, we can eliminate some factors.

If you have an odd coefficient on the middle term,

you can eliminate any pairs of even factors.

So the group I crossed out in purple below will be eliminated.

Another strategy is to use factors a little closer together.

So I would go with the 4 and 3 group.

Surely enough, our trinomial does factor with the 4 and 3.

Now set the factored trinomial equal to 0.

Then use zero product property and you have your answer.
