Answer:

Multiply both sides of the inequality by –3. Change the direction of the inequality. Subtract 2 from both sides of the inequality.

Step-by-step explanation:

the steps to solving the inequality $\frac{g+2}{-3}$

To solve this inequality , we need to isolate g

To get 'g' alone we need to remove the number from the numerator

To remove -3 from the denominator , we multiply by -3 on both sides

when we divide or multiply by a negative number , we flip the inequality sign

< becomes > symbol

$-3*\frac{g+2}{-3} >-2*(-3)$

$g+2 > 6$ , then we subtract 2 on both sides

$g > 4$

Steps are : Multiply both sides of the inequality by –3. Change the direction of the inequality. Subtract 2 from both sides of the inequality.

How long does it take a person to skate the length of a hockey rink (200 feet) at a constant speed of 8 feet per second?

Svetradugi [14.3K]

$V=\frac{d}{t}=> \boxed{t=\frac{d}{V}} \\\\ V-the \ speed \\ d-the \ distance \\ t-time \\\\ t=\frac{200ft}{8\frac{ft}{s}}= \frac{200ft}{1}*\frac{1}{8}\frac{s}{ft} \\\\ \boxed{t=25s}$

Reposed cause the first one didn’t have the pictures. Need help with this <br> Thanks :)

Answer:

(d) x = -3/4; y = -3 1/2

Step-by-step explanation:

You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.

<h3>Interpolation</h3>

The idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.

In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.

<h3>Application</h3>

<u>horizontal coordinate</u>

The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.

x = -3/4

<u>vertical coordinate</u>

The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.

y = -3 1/2

2.<br> If AB = 9x - 2 and BC = 6x + 13,<br> then BC = ?<br> A<br> B<br> С

vovangra [49]

Answer:

AB = 9x - 2
BC = 6x + 13

Since both have equal length

9x - 2 = 6x + 13

9x - 6x = 13 + 2

3x = 15

x = 15/3

x = 5

Length of BC = 6(5) + 13 = 43 cm

A data set lists earthquake depths. The summary statistics are

irinina [24]

Answer:

Step-by-step explanation:

The summary of the given statistics data include:

sample size n = 400

sample mean $\overline x$ = 6.86

standard deviation = 4.37

Level of significance ∝ = 0.01

Population Mean $\mu$ = 6.00

Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.

To start with the hypothesis;

The null and the alternative hypothesis can be computed as :

$H_o: \mu = 6.00 \\ \\ H_1 : \mu \neq 6.00$
