-5x ≥ 90
Divide both sides by -5
x ≤ -18
17. 5x - 2 ≤ -7
Add 2 to both sides
5x ≤ -7 + 2
5x ≤ -5
x ≤ -1
18. 6 - x ≤ 14
Subtract 6 from both sides
-x ≤ 14 - 6
-x ≤ -8
x ≥ 8
19. 4 - 1/3x > 11
Subtract 4 from both sides
-1/3x > 11 - 4

The ratio between Siu's height and the height of her brother Tai is 5:6. If
Tai is 145 cm tall, how tall is Siu, to the nearest centimetre?
With the concepts of ratio, Siu's height is 121 cm tall.
What is a ratio?We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part to part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.
A ratio is a comparison between two amounts that often uses a fraction.
Considering that the fraction has been simplified,
Given that Siu's height is 5x
Tai's height is 6x.
Now, 6x= 145
Thus, x= 145/6
Now, Siu's height is 5x
Then, its height is (145 ×5)/6= 120.8 cm
Siu's height is 121 cm because it must be rounded to the closest centimeter.

The correct equations which can be used to represent when she will be able to purchase the bicycle she wants are:
250 = 125+25c125 = 25cc = 5Given, Eva wants to buy a bicycle.
The cost of bicycle is = $250
Saving's of Eva = $125
Eva plans on washing cars for $25 per car.
Eva wash 'c' cars to have enough to purchase the bicycle.
cost of bicycle = saving's of Eva + Eva washing 'c' cars for $25 per car.
⇒ 250 = 125 + 25c
arrange the like terms on one side.
⇒ 250 - 125 = 25c
⇒ 125 = 25c
⇒ 25c = 125
⇒ c = 125/25
⇒ c = 5
hence Eva washes 5 cars to earn $125 which gets added to the savings and becomes the cost of the bicycle she wants to purchase.
⇒ cost of bicycle = 125+25(5)
⇒ cost of bicycle = 125+125
⇒ cost of bicycle = $250

The measure of the lableled angles are x = 202 and (x - 44) = 158
What are the values of the labeled angles?Before we can solve this question, we need to understand the geometry of the shape.
The shape we have here is a pentagon. The sum of angles in a pentagon is 540. The angle with a red square is a right angle and the value is 90.
Therefore:
x + 90 + 90 + (x - 44) = 540
x + 180 + x - 44 = 540
2x + 136 = 540
2x = 540 - 136
2x = 404
x = 404/2
x = 202
Also:
(x - 44) = 202 - 44 = 158
Therefore, the angles x and (x - 44) measure 202 and 158 respectively.

Which line on the xy-plane has a positive slope?
Line 1
Line 2
Line 3
Line 4
Please only answer with the options provided
Line 2 has a positive slope with respect to the angle made with the x-axis.
What is the slope?Slope refers to the tan of the angle with the x-axis. For example. if the line makes an angle β with the x-axis, then the slope is the tan β.
Now taking line 1,
The line is parallel to the x-axis, therefore the line makes 0 angles with the axis which gives slope 0.
Now taking line 2,
The line passes to the origin and has the equation x=y, thus the slope is 1
Now taking line 3,
The line is parallel to the y-axis, therefore the line makes 90°, thus the slope is 1/0 which gives infinity.
Now taking line 4,
The line is making an angle of 60°, therefore the line is having a slope: - [tex]\sqrt{3}[/tex]

3. 0 = 315 degrees
Using trigonometry, it is found that:
1. Graph 2 shows an angle in which cos(θ) = -8/17 and sin (θ) is negative.
2. The angles are θ = 157.38º and θ = 202.62º, as shown in Graph 1.
3. Graph 3 shows an angle of θ = 315º.
Sine and cosine negativeIn item 1, it asks for an angle in which both the sine and the cosine of the angle are negative. This happens in the third quadrant, hence Graph 2 shows an angle in which cos(θ) = -8/17 and sin (θ) is negative.
SecantThe secant of an angle is given by one divided by the cosine of the angle, that is:
sec(θ) = 1/cos(θ)
Considering the numeric value of the secant in this problem, we have that:
-13/12 = 1/cos(θ)
-13cos(θ) = 12
cos(θ) = -12/13
The cosine is negative in the second and the third quadrant, hence graph 1 shows these equivalent angles.
Applying the inverse cosine, the angles are given as follows:
θ = arccos(-12/13)
θ = 157.38º and θ = 202.62º. (two equivalent angles).

with pic. Which of the following functions is graphed below?
The picture is represented by the absolute value function g(x) = |x - 5| - 4. (Correct choice: A)
How to derive the absolute function associated with the picture
Absolute values are functions defined by the following piecewise function:
f(x) = |x| = x for x ≥ 0.f(x) = |x| = - x for x < 0.The function in the picture is the consequence of the following rigid transformations:
Horizontal translation 5 units in the + x direction.Vertical translation 4 units in the - y direction.Now we proceed to obtain the image of f(x):
Horizontal translation
f'(x) = |x - 5|
Vertical translation
g(x) = |x - 5| - 4
The picture is represented by the function g(x) = |x - 5| - 4.

A pet hotel charges $25 per night to keep a dog. When the dog arrives, there is a mandatory $15 examination fee. Part A: Write a function rule for the total cost T, including the mandatory examination, for a dog to stay at the hotel for n days. Part B: How much would a 6 night stay cost? Part C: Does a 3 night stay cost half as much as a 6 day stay since it is half the time? Explain in detail!
A) A function rule for the total cost T, including the mandatory examination, for a dog to stay at the hotel for n days is; T = 25n + 15
B) The total cost to stay for 6 nights is; $165
C) No, 3 night does not cost half as much as the cost for 6 nights due to the addition mandatory cost of $15.
How to solve algebra word problems?We are told that a pet hotel charges $25 per night to keep a dog. We are also told that there is a mandatory $15 examination fee when the dog arrives there.
A) If the number of nights spent is n, then the function rule here for the total cost is;
T = 25n + 15
B) We are told that the number of nights is 6 nights. Thus, we will just plug in 6 for n into the total cost equation to get;
T(6) = 25(6) + 15
T(6) = $165
C) The cost of 3 nights would be;
T(3) = 25(3) + 15
T(3) = $90
This is more than half of the cost of 6 nights.

A number is selected randomly from a container containing all the integers from 10 to 50. Find P(Prime|between 11 and 30).A. 7/10B. 1/2C. 1D. 3/10
Given:
Numbers in the container: All integers from 10 to 50
Let's find P(Prime numbers| numbers between 11 and 30).
Here, we are to find the conditional probability.
Apply the formula:
P(Prime|between 11 and 30) = P(prime numbers and between 11 and 30) ÷ P(numbers between 11 and 30).
Where:
• Prime numbers between 11 and 30 = 11 , 13 , 17 , 19 , 23 , 29 =6 numbers
,• Intergers from 10 to 50 = 41 integers.
To find the probability, we have:
[tex]\begin{gathered} P(Prime|between11and30)=\frac{\frac{6}{41}}{\frac{20}{41}} \\ \\ =\frac{6}{41}\ast\frac{41}{20} \\ \\ =\frac{6}{20} \\ \\ =\frac{3}{10} \end{gathered}[/tex]Therefore, we have:
P(Prime|between 11 and 30) = 3/10.
ANSWER:
D. 3/10
