Answer:
[tex]\sf D. \quad t < -4, t > 5[/tex]
Step-by-step explanation:
Given system of inequalities:
[tex]\begin{cases}5t-1 < -21\\4t+2 > 22\end{cases}[/tex]
Solve the inequalities by isolating t.
Inequality 1
[tex]\sf \implies 5t-1 < -21[/tex]
[tex]\implies \sf 5t-1+1 < -21+1[/tex]
[tex]\sf \implies 5t < -20[/tex]
[tex]\sf \implies 5t \div 5 < -20 \div 5[/tex]
[tex]\sf \implies t < -4[/tex]
Inequality 2
[tex]\sf \implies 4t+2 > 22[/tex]
[tex]\sf \implies 4t+2-2 > 22-2[/tex]
[tex]\sf \implies 4t > 20[/tex]
[tex]\sf \implies 4t \div 4 > 20 \div 4[/tex]
[tex]\sf \implies t > 5[/tex]
Therefore, the solution to the system of inequities is:
[tex]\sf t < -4, t > 5[/tex]
When graphing inequalities:
< or > : dashed lines≤ or ≥ : solid line< or ≤ : shading under the line> or ≥ : shading above the lineTherefore, to graph the given system of inequalities:
Draw a straight dashed line at t = -4 and shade under the line.Draw a straight dashed line at t = 5 and shade above the line.(Refer to attachment for the graph).

How can you find out the similarities and differences in a non-fiction text?
A. look at how the characters speak
B. look at how the subject or events are portrayed
C. look at the genre
The similarities and differences in a non-fiction text look at how the subject or events are portrayed.
What is a non-fiction text?Comparing non-fiction texts can focus on the similarities between the texts - things they have in common. You can also contrast texts and focus on their differences - things that set the texts apart from each other. You could compare and contrast the following:
Form – What types of text (letter, news report, etc) are they?
Purpose – What job (persuading, informing, advertising) is each text doing?
Audience – Who is the intended reader of the text?
Subject matter – What are the texts about?
Language choices – What kinds of words, images or rhetorical devices are being used?
Structure – How is the text ordered?
Tone – What is the overall tone or mood of the writing?
Non-fiction texts are all around us, and comparing them can help you become more aware of how language is being used in society. Comparing non-fiction texts can often prompt you to notice things that you might not have considered about a text in isolation.
Hence the similarities and differences in a non-fiction text look at how the subject or events are portrayed.

What is the value of x in the equation 1/5x - 2/3y = 30, when y = 15?
A. 4
B. 8
C. 80
D. 200
200
Step-by-step explanation:
1/5x -2/3y =30
Plug in 15 for y.
x-(15)= 30
2/3x of 2/3(15) is 10.
1/5x -10-30
Add 10 to each side.
1/5x = 40
Divide each side by 1/5.
(dividing by a fraction is the same as multiplying by its reciprocal...flip 1/5...*5)

In how many ways can we stack 10 books?
The arrangement of items can be done with the use of permutation. The stacking of the number of books in the question can be done in 3,628,800 ways.
The arrangement of a given number of items can be done when definite numbers are to be considered at once by the use of permutation. A permutation is a mathematical method that can be used to determine the number of ways by which given items are to be arranged in a particular order.
Given that 10 books are to be stacked, the number of ways (n) that this can be done can be determined by:
n = 10!
= 10 x 9 x 8 x7 x6 x5 x4 x3 x2x 1
n = 3,628,800
Therefore, the 10 books can be stacked in 3,628,800 ways.

a) If 2 Tan a = 3 Tan B, then show that Tan (a-B) =5 sin2b/5Cos 2B-1
Given that :-
2 tan A = 3 tan BProve that :-
Tan (a-B) = [ sin 2B/(5 – cos 2B)]Taking RHS :-
= sin 2B/(5 – cos 2B)] = [(2 tan B)/(1 + tan2B)]/ [5 – {(1 – tan2B)/(1 + tan2B)}]
= (2 tan B)/ [5(1 + tan2B) – 1 + tan2B]
= (2 tan B)/[5 + 5 tan2B – 1 + tan2B)
= (2 tan B)/(4 + 6 tan2B)
= (2 tan B)/[2(2 + 3 tan2B)]
= tan B/(2 + 3 tan B tan B)
Dividing the numerator and denominator by 2,
= [(1/2) tan B]/ [1 + (3/2) tan B tan B]
= [(3/2) tan B – tan B]/[1 + tan A tan B] {from (i)}
= (tan A – tan B)/(1 + tan A tan B)
= tan(A – B) = LHS

Step-by-step explanation:
Let's call the midpoint of OP, R.
The triangle of OQR would be an equilateral triangle since OQ = OR as they are both radii and is OQR and ORQ are 60º, ROQ is also 60º, making the triangle equilateral. Because tangents meet a circle at 90º, the angle RQP would be 30º and since angles on a straight line add to 180º, the angle QRP would be 180-ORQ which is 120º. Now we know the 2 angles in triangle of QRP so we can work out the final angle since angles in a triangle add to 180º. So:
180 - 120 - 30 = 30º.
x = 30º
This would also prove that QR and RP are the same since base angles in an isosceles triangle are equal.

Answer:
3. (3, 6)
4. (3, 7)
5. (3, 36)
Step-by-step explanation:
These are slope functions, so there's is no definite answer for x as it tells you to solve when x is 3. So put simply lets do that. Knowing that x is now 3, we can solve for all the functions. This will give you y, which is f(x) which just tells you the equations represents a function or slope on a graph. All these equations create lines. Solving for question 3, 3 + 3 is 6, so f(x) = 6, and the answer is (3, 6). For 4, you do 3 x 3 - 2, which is 9 - 2 = 7. So (3, 7). So on and so forth.

A car travels for 7 hours and 50 minutes at an average speed of 130 km/h. How far has the car travelled (in km)?
The car that travels for 7 hours and 50 minutes at an average speed of 130 km/h covered a distance of 1017.9 km.
How to find the distance travelled by a car?The car travels for 7 hours and 50minutes at an average speed of 130 km/h.
Therefore,
speed = distance / time
speed = 130 km/h
time = 7 hours 50minutes = 7 + 0.833333 = 7.83 hours
Therefore,
130 = distance / 7.83
