Solve for x:−2(x+9)=−1(x+−1)+2

Answer:

I'm pretty sure it is D

Step-by-step explanation:

sry if I am wrong

The fourth graph is representing the inequality x ≤ 7, so option D is correct.

Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal.

Given:

The inequality = x ≤ 7,

As this inequality representing the value of x is less than 7 or can be equal to 7, In this graph

Option D is representing the inequality, as the graph is suggesting x can be equal to 7 or less than 7.

Therefore, the fourth graph is representing the inequality x ≤ 7.

Answer:

x and y = 19

Step-by-step explanation:

sin 45/x = sin90/19[tex]\sqrt{2}[/tex]

19[tex]\sqrt{2}[/tex]×sin45=sin90x

x=19

Pythagorean theorem for y

[tex]y^{2}[/tex]=(19[tex]\sqrt{2}[/tex])^2 - 19^2

y^2= 722 - 361

y^2= 361

y=19

Answer:

Step-by-step explanation:

If the bricklayer can construct the wall in its entirety in 3 hours, then he can get 1/3 of the job done in an hour.

If the apprentice can get the whole job done in 5 hours, then he can get 1/5 of the job done in an hour. If they both work together on said job, the equation is

[tex]\frac{1}{3}+\frac{1}{5}=\frac{1}{x}[/tex] and now we solve for x. Multiply everything by the LCM to get rid of the fractions. That would be 15x:

[tex]15x(\frac{1}{3}+\frac{1}{5}=\frac{1}{x})[/tex] and doing that gives us

5x + 3x = 15 and

8x = 15 so

x = 1.875 hours which is 1 7/8 hours which is also 1 hour and 52 1/2 minutes.

0.8k - 20 = -60

Step 2: Solve for k

Answer:

k = - 50

Step-by-step explanation:

0.8 k - 20 = - 60

Add 20 to each side

0.8 k - 20 + 20 = - 60 + 20

0.8 k = - 40

divide each side by 0.8

0.8 k / 0.8 = -40 / 0.8

k = - 50

Answer:

The area of the sector of the circle is approximately

Step-by-step explanation:

The given parameters of the circle having a shaded sector are;

The radius of the circle, r = 4 meters

The measure of the arc bounding the sector = 135°

The area of a sector of a circle, 'A', is given as follows;

[tex]A = \dfrac{\theta}{360 ^{\circ}} \times \pi \times r^2[/tex]

Therefore, the area, 'A' of the given sector of the circle, is given as follows;

[tex]A = \dfrac{135 ^{\circ}}{360 ^{\circ}} \times \pi \times (4\ cm)^2 \approx 18.85 \ cm^2[/tex]

The area of the sector of the circle, with radius 4 cm and bounded by an arc, A ≈ 18.82 cm².

Answer:

1) I and III

Step-by-step explanation:

The equation of an exponential function is given by:

y = abˣ

where x is an independent variable, y is a dependent variable, a is the initial value of y (that is value of y at x = 0), b is greater than 1 for an exponential growth while b < 1 for an exponential decay.

Given that x represent years and P(x) represent population. 2013 is represented by x= 0, hence:

At the year 2013 (x = 0), the population is 3810, hence a = 3810.

The equation becomes:

P(x) = 3810(b)ˣ

At 2014 (x = 1), the population is 3943. Hence:

3943 = 3810(b)¹

3810b = 3943

b = 1.035.

Therefore a = 3810, b = 1.035. The correct option is 1) I and III

Since b > 1, this is an exponential growth.

Answer:

5x = 5(10) = 50 inches

Step-by-step explanation:

Let x = length of shorter piece  then

5x = length of the longer piece

.

x + 5x = 60

6x = 60

x = 10 inches (shorter piece)

.

Longer piece:

5x = 5(10) = 50 inches

Answer:

x ≥ - 7

Step-by-step explanation:

3(x - 4) ≥ 5x + 2

3x - 12 ≥ 5x + 2

3x - 12 + 12 ≥ 5x + 2 + 12

3x - 5x ≥ 5x - 5x + 14

- 2x ≥ 14

- 2x ÷ - 2 ≥ 14 ÷ - 2

x ≥ - 7

Pelican Beach has a median temperature above 80 degrees and the smallest interquartile range.

'A boxplot is a standardized way of displaying the distribution of data based on a five number summary, minimum, first quartile, median, third quartile, and maximum. It can tell us about the outliers and what their values are.'

According to the given problem,

In the given box plots, Whispering Palms and Pelican Beach has a median temperature of above 80 degrees. The median is the middle-most line that divides the box plot into two parts. Their median is approximately 85 degrees.

The interquartile range is the difference between the end points of the box plot.

Pelican Beach has the smallest interquartile range since the difference between the end points is less than the interquartile range of Whispering Palms.

Hence, we can conclude, Pelican Beach ahs the median temperature above 80 degrees and the smallest interquartile range.
