According to the graph, what is the solution (ordered pair) of this system of equations?
Answers
Answers:
(2, -3) and (3, -3)
==================================================
Work Shown:
Since f(x) = -3, we'll replace f(x) with -3 and solve for x
f(x) = x^2 - 5x + 3
-3 = x^2 - 5x + 3 .... f(x) replaced with -3
0 = x^2 - 5x + 3 + 3 ... adding 3 to both sides
0 = x^2 - 5x + 6
x^2 - 5x + 6 = 0
(x - 3)(x - 2) = 0 .... factor; you can also apply the quadratic formula
x-3=0 or x-2=0
x = 3 or x = 2
So that explains where that '2' comes from when they listed (2, ?)
-------------
To find what replaces the question mark, we will plug x = 2 into the function
f(x) = x^2 - 5x + 3
f(2) = 2^2 - 5(2) + 3
f(2) = 4 - 10 + 3
f(2) = -3
We could have skipped this portion and said that the solution is (2,-3) but plugging x = 2 into the function to get the output y = -3 helps confirm that x = 2 is one of the x solutions.
-------------
Let's do the same for x = 3
f(x) = x^2 - 5x + 3
f(3) = 3^2 - 5(3) + 3
f(3) = 9 - 15 + 3
f(3) = -3
We end up with the same output, so x = 3 is confirmed as well.
The graph below visually helps reinforce these confirmations. Each solution is an intersection between the two curves.

An aeroplane flew from Qatar to Bahrain. The distance flown was 135 km. The average speed was 180 km/h. Work out the time taken. Give your answer in minutes
Answers
Given:
The distance flown was 135 km.
The average speed was 180 km/h.
To find:
The time taken by the airplane.
Solution:
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]Time=\dfrac{Distance}{Speed}[/tex]
Putting Distance = 135 and Speed = 180, we get
[tex]Time=\dfrac{135}{180}[/tex]
[tex]Time=0.75[/tex]
The time taken by the airplane is 0.75 hours.
We know that,
1 hour = 60 min
0.75 hour = 0.75 × 60 min
0.75 hour = 45 min
Therefore, the time taken by the airplane is 45 min.

Explanation:
We have n = 8 sides for this octagon.
This means the interior angles sum to 180(n-2) = 180(8-2) = 180*6 = 1080 degrees.
The tickmarks tell us that each side is the same length, so we have a regular octagon. This means that all 8 angles are the same measure. Let's say each angle is y degrees.
1 angle = y degrees
8 angles = 8y degrees
Solving 8y = 1080 leads to y = 1080/8 = 135
Each angle of this regular octagon is 135 degrees.
--------------------
Now set 16x+23 equal to 135 and solve for x
16x+23 = 135
16x+23-23 = 135-23
16x = 112
16x/16 = 112/16
x = 7
5. Line 2x -3y = 6 is transformed by a dilation a scale factor of 2 and centered at the (3, 0). What is the equation of the line after the dilation?
Answers
Answer:
2x-3y=6
Step-by-step explanation:
To keep it short, since one of the points o the equation 2x-3y=6 is on the line and is the center of the non rigid transformation we can stretch or compress however long we want, the equation or slope will stay the same since slopes are proportional for example the slope in this problem is 2/3. If we multiply the line by a scale factor of 2, the lines are similar and the slope is 4/6 which is the same as 2/3. So the equation stays the same

Answer:
Step-by-step explanation:
First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem
A^2+B^2=C^2.
We know A^2 and B^2, so we need to substitute that into the equation
2^2+4^2=C^2
so now, simplify.
4+16=C^2
20=C^2
Square root of 20 is about 4.5
so 4.5 is the length of the sides of the square.
4.5x4.5=20.25

Answer: 1.65
I hope this isn't too late : )
The cost of 1 lb of sugar candies is $1.65.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
Explanation
Given to us
weight of candy mix = 100 lb,
weight of jelly beans = 100 lb,
Cost of jelly beans = 20 cent per lb = $0.20 per lb,
Cost of candy mix = $1.36 per lb.
Total cost of candy mix:
Total cost of candy mix = weight of candy mix * Cost of candy mix
= 100 lb * $1.36
Total cost of Jelly beans:
Total cost of Jelly beans = weight of Jelly beans * Cost of Jelly beans
= 20 lb* $0.20
Weight of Sugar candies:
weight of Sugar candies = weight of candy mix - weight of jelly bean
= 80 lb
Total cost of sugar candies:
Total cost of candy mix = Total cost of jelly beans + total cost of sugar candies
100 lb * $1.36 = 20 lb* $0.20+ 80lb*x
solving we get,
x = 1.65
Hence, the cost of 1 lb of sugar candies is $1.65.

In triangle ABC, the measure of C is 90°,
AC=24, and BC=10. What is the value of sin
A?
Answers
Answer:
Sin A = 0.38462
Step-by-step explanation:
From the trigonometric function,
Sin A = [tex]\frac{Opposite}{Hypotenuse}[/tex] ................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
[tex]/Hyp/^{2}[/tex] = [tex]/Opp/^{2}[/tex] + [tex]/Adj/^{2}[/tex]
= [tex]24^{2}[/tex] + [tex]10^{2}[/tex]
= 576 + 100
[tex]/Hyp/^{2}[/tex] = 676
Hyp = [tex]\sqrt{676}[/tex]
= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A = [tex]\frac{10}{26}[/tex]
Sin A = 0.38462
