The expression that is equivalent to [(4a + 4)/2a] * [a²/(a + 1)] after simplification is; 2a

<h3>How to Simplify Fractions?</h3>

We want to simplify the expression;

[(4a + 4)/2a] * [a²/(a + 1)]

This expression can be further reduced to;

[(4a + 4)/2] * [a/(a + 1)]

Factorizing the numerator to get;

[(4(a + 1)/2] * [a/(a + 1)]

(a + 1) will cancel out to get;

Answer:

Let m = Number of months

Company A: 60+ 42.95 m

Company B: 25+49.95 m

60+ 42.95 m= 25+49.95 m

Subtract 42.95 from both sides

60 = 25 + 7m

Subtract 25 from both sides

35= 7m

Divide both sides by 7

Answer:

1.) scatter plot is attached below.

There is no sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals.

Step-by-step explanation:

Given the data :

Overhead width : 7.2 7.5 9.7 9.3 8.7 8.2

Weight : 119 156 243 200 199 188

The linear correlation Coefficient, R = 0.946

Using the Pvalue calculator for R score ;

Pvalue = 0.0149

Since, Pvalue > Α ; WE fail to reject the Null and conclude that there is no sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals.

Tyler makes $10 per hour at his job.The function f(x)=10x gives the amount of money Tyler makes after x hours.Graph this functio

Finger [1]

You will have the points: (0,0) and (1,10) and (2,20) and (3,30) etc etc

Plot at least 2 of these points. Then draw a line through them.

Each point has an x,y pair such that the y value is ten times the x value

For example, if x = 2, then

y = 10*x = 10*2 = 20

so that shows how (2,20) is one of the points.

-------------------

The domain would be the set of positive whole numbers assuming Tyler can only work a whole number of hours. If partial time values are accepted, then the domain would be the set of positive real numbers. Negative x values are not allowed as Tyler can't work negative 3 hours for instance.

In a similar fashion, the range is the set {0, 10, 20, 30, 40, ...} incrementing by multiples of 10 if x is the set of positive whole numbers. If x is the set of positive real numbers, then y can be 0 or larger which sets up the range of y being the set of positive real numbers as well.

Alguien me podría ayudar con esos problemas? :D

riadik2000 [5.3K]

Answer:

3. $\frac{1}{12}$

4. $\frac{22}{3}$

5. $\frac{5}{42}$

8. $\frac{8}{63}$

9. $-\frac{7}{54}$

10. $-\frac{3}{16}$

Step-by-step explanation:

$\frac{-6}{8} *\frac{1}{-9} =\frac{-6}{-72}$

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 6

$\frac{1}{12}$

$\frac{11}{3}*\frac{4}{2} =\frac{44}{6}$

ahora simplifica, los dos nu$meros se pueden simplificar por 2

$\frac{22}{3}$

$\frac{5}{-3}*\frac{-2}{7}* \frac{1}{4} =\frac{-10}{-84}$

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 2

$\frac{5}{42}$

$\frac{20}{-5}*\frac{1}{-9}* \frac{-2}{-7} =\frac{-40}{-315}$

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 5

$\frac{8}{63}$

$\frac{2}{3}*\frac{-7}{-9}* \frac{-1}{4} =\frac{14}{-108}$

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero positivo dividido por un numero negativo se convierte en negativo. Los dos nu$meros se pueden simplificar por 2

$-\frac{7}{54}$

10.

$\frac{9}{-12}*\frac{-4}{16} =\frac{-36}{-192}$

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 12

$-\frac{3}{16}$

Espero y te ayude esto! (:
