Answer:

The greatest common factor of 14x² - 4x is: 2x

Step-by-step explanation:

Given the expression

14x² - 4x

The first step is to factor out the greatest common factor from each term

14x² = 2 · 7 · 14 · x · x

4x = 2 · 4 · x

G.C.F = 2 · x

G.C.F = 2x

Therefore, the greatest common factor of 14x² - 4x is: 2x

Y=8-2x when x=8 the value of y

Lera25 [3.4K]

Answer:

-8

Step-by-step explanation:

Given that x and y are two variables. they are related by the function

y =8-2x

Since x and y are related, given one value we can find the other using this equation.

In our question, given that x =8

Substitute x value in the equation

y = 8-2x

y =8-2(8) = -8

Hence answer is -8:

Verify: We verify by putting -8 for y and check whether x =8

-8=8-2x

Or 2x = 16

x =8

Find parametric equations through point P=(2,2,7) in the direction of the vector v = (44, 14, -20)?

ycow [4]

Answer:

(x, y, z) = (2+44t, 2+14t, 7-20t)

Step-by-step explanation:

One way to write parametric equations for line L is ...

L = P + t·<em>v</em>

where P is the given point and <em>v</em> is the given direction vector. Using that form, we have ...

(x, y, z) = (2+44t, 2+14t, 7-20t)

If you like, you can remove a common factor of 2 from the coefficients of t.

(x, y, z) = (2+22t, 2+7t, 7-10t)

Answer:

The test statistic is $t = 3.744$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 140$

The The level of significance is $\alpha = 0.05$

The sample size is n = 18

The null hypothesis is $H_o : \mu = 140$

The alternative hypothesis is $H_a : \mu > 140$

The sample mean is $\= x = 155$

The standard deviation is $\sigma = 17$

Generally the test statistics is mathematically represented as

$t = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

substituting values

$t = \frac{ 155 - 140 }{ \frac{ 17 }{ \sqrt{18} } }$

$t = 3.744$
