find an equation of the line passing through the point (-4,-6) that is parellel to the line y=-2/9x-1

ryzh [129]

<em><u>The equation of the line passing through the point (-4,-6) in slope intercept form is:</u></em>

$y = \frac{-2}{9}x -\frac{62}{9}$

<em><u>Solution:</u></em>

Given that we have to write the equation of the line passing through the point (-4,-6) that is parallel to the line y=-2/9x-1

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ---------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

<em><u>Given equation of line is:</u></em>

$y = \frac{-2x}{9} -1$

<em><u>On comparing the above equation with eqn 1,</u></em>

$m = \frac{-2}{9}$

We know that slopes of parallel lines are equal

Thus slope of line parallel to given line is also $\frac{-2}{9}$

Now find the equation of line with slope $\frac{-2}{9}$ and passing through (-4, -6)

$\text{Substitute } m = \frac{-2}{9} \text{ and } (x, y) = (-4, -6) \text{ in eqn 1}\\\\-6=\frac{-2}{9} \times -4+c\\\\-6 = \frac{8}{9}+c\\\\-6 = \frac{8+9c}{9}\\\\-54 = 8+9c\\\\9c = -62\\\\c = \frac{-62}{9}$

$\text{Substitute } m = \frac{-2}{9} \text{ and } c = \frac{-62}{9} \text{ in eqn 1}\\\\y = \frac{-2}{9}x -\frac{62}{9}$

Thus the equation of line is found

Winnie wrote the following riddle.I am a number between 60 and 100.My ones digit is two less than my tens digit.I am a prime num

Kazeer [188]

Answer:

79

Step-by-step explanation:

60<xy<100

y -2 =x

if it is prime

y cannot be even

so y could be 1,3,5,7,9

x would then be 9,1,3,5,7

but to be between 60 and 100

x must be 7 or 9

so the number must be 79 or 57

57 is not prime so

the number is 79

In establishing warranties on HDTV sets, the manufacturer wants to set the limits so that few will need repair at the manufactur

Novosadov [1.4K]

Answer:

If the warranty limits are at 41.12 months, only 10 percent of the HDTVs need repairs at the manufacturer's expense.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

For a new HDTV the mean number of months until repairs are needed is 36.84 with a standard deviation of 3.34 months. This means that $\mu = 36.84, \sigma = 3.34$ .

Where should the warranty limits be set so that only 10 percent of the HDTVs need repairs at the manufacturer's expense?

This is the value of X when Z has a pvalue of 0.90.

Looking at the z-table, we get that this is between $Z = 1.28$ and $Z = 1.29$ , so we use $Z = 1.285$ .

$Z = \frac{X - \mu}{\sigma}$

$1.28 = \frac{X - 36.84}{3.34}$

$X - 36.84 = 1.28*3.34$

$X = 41.12$

If the warranty limits are at 41.12 months, only 10 percent of the HDTVs need repairs at the manufacturer's expense.

Suppose the supply and demand for a certain textbook are given by supply: p equals one half q squared comma demand: p equals n

vampirchik [111]

Answer:

Demand quantity: 6.3246

Supply quantity: 4.4721

Step-by-step explanation:

Supply equation:

p = (1/2) * q^2

Demand equation:

p = -(1/2) * q^2 + 30

(p is the price, q is the quantity)

If the price p is equal to 10, then we can calculate:

Supply quantity:

10 = 0.5 * q^2

q^2 = 20

q = 4.4721

Demand quantity:

10 = -0.5 * q^2 + 30

0.5 * q^2 = 20

q^2 = 40

q = 6.3246
