Final answer:
The correct pair (a,b) that solves the given system of equations 2a + b = 3 and a - 3b = 5 is (2, -1), which is option J.
Explanation:
To find which pair (a,b) is the solution to the system of equations 2a + b = 3 and a - 3b = 5, we can use substitution or elimination. Here's a step-by-step explanation using the elimination method:
Multiply the second equation by 2 to align the coefficients of a: 2(a - 3b) = 2(5) gives us 2a - 6b = 10.Add this new equation to the first equation: (2a + b) + (2a - 6b) = 3 + 10, simplifying to 4a - 5b = 13.Now we solve this new equation for a: a = (13 + 5b) / 4.Substitute this expression for a in one of the original equations: 2((13 + 5b) / 4) + b = 3.Simplify and solve for b: (13 + 5b)/2 + b = 3, which gives b = -1.Now that we have b, we can find a: 2a - 1 = 3 which gives a = 2.Therefore, the correct solution to the system of equations is (2, -1), which corresponds to option J.

Step-by-step explanation:
csc(x) = 1/sin(x)

cos(x)*csc(x) = cos(x)/sin(x)
cos(x)*csc(x) = cot(x)
----
abbreviations
csc = cosecant
cos = cosine
sin = sine
cot = cotangent
To simplify cos x csc x, we can replace csc x with 1/sin x based on the trigonometric identity. This will give us cos x/sin x, which is the same as cot x based on the trig identities.
Explanation:The question is asking us to simplify the expression cos x csc x. To do this, we can use the trigonometric identity sin = 1/csc, which tells us what csc x is in terms of sin x.
So if that is the case, we can rewrite csc x as 1/sin x and replace csc x in the original expression giving us cos x * (1/sin x) or equivalently cos x/sin x.
And if we look at our trigonometric identities again, we can find that cos x/sin x is the same as cot x, our final simplified expression.

In triangle abc , side BC is 3 inches long and side AB is 16 inches long. Angle A measures 20 °. Given that angle C is an obtuse angle, find the measure of angle C. Round to the nearest tenth of a degree
Answers
Answer:
Angle C is 101 degrees
Step-by-step explanation:
Given triangle ABC,
Side BC =3
Side AB =16
Angle A=20
Also, Angle C is an obtuse angle.
To find Angle C:
As shown in figure,
By using basic trigonometry,
Angle A =20 and AB=13
BD =13sin20 and AD = 13cos20
Now, AD=AC+CD
CD=13cos20-3
CD=2.30506
And BD =13sin20=11.86828
In triangle BDC,
Tan(BCD) = [tex]\frac{BD}{CD}[/tex]
Tan(BCD) = [tex]\frac{11.86828}{2.30506}[/tex]
Tan(BCD) = [tex]\frac{11.86828}{2.30506}[/tex]=5.1487
Angle BCD = 79.00
Therefore, Angle BCA =180-Angle BCD=180-79=101.
Angle C is 101 degrees
The measure of angle C in triangle ABC is approximately 150.8° when rounded to the nearest tenth of a degree.
To find the measure of angle C, we can use the fact that the sum of the angles in any triangle is 180°. Given that angle A is 20° and angle C is obtuse, we can set up the following equation:
[tex]\[ \angle A + \angle B + \angle C = 180 \][/tex]
Since angle A is 20°, we can substitute this value into the equation:
[tex]\[ 20 + \angle B + \angle C = 180 \][/tex]
To find the measure of angle B, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle:
[tex]\[ \frac{a}{\sin(\angle A)} = \frac{b}{\sin(\angle B)} = \frac{c}{\sin(\angle C)} \][/tex]
We can use the sides AB and BC to find angle B:
[tex]\[ \frac{16}{\sin(20)} = \frac{3}{\sin(\angle B)} \][/tex]
Solving for[tex]\(\sin(\angle B)\)[/tex]:
[tex]\[ \sin(\angle B) = \frac{3}{16} \cdot \sin(20) \][/tex]
Now, we calculate the value of [tex]\(\sin(\angle B)\)[/tex]:
[tex]\[ \sin(\angle B) = \frac{3}{16} \cdot \sin(20) \approx \frac{3}{16} \cdot 0.3420 \approx 0.0649 \][/tex]
Taking the inverse sine [tex](sine) of \(\sin(\angle B)\)[/tex] gives us the measure of angle B :
[tex]\[ \angle B = \sin(0.0649) \approx 3.7 \][/tex]
Now we have the measures of angles A and B, so we can find angle C :
[tex]\[ 20 + 3.7 + \angle C = 180 \] \\[/tex]
[tex]\[ \angle C = 180 - 20 - 3.7\] \\[/tex]
[tex]\[ \angle C = 180 - 23.7 \] \\[/tex]
[tex]\[ \angle C = 156.3 \][/tex]
Since angle C is obtuse, we do not need to consider any other solutions for angle B that might be less than 90°. Therefore, the measure of angle C is approximately 156.3°, which rounds to the nearest tenth of a degree as 150.8°.

Antony and Lily started moving in opposite directions from the same point at the same time. If Antony was biking with average 12 mph speed and Lily was walking by 4 mph, how soon the distance between them will be 76 miles?
Answers
4 hours and 45 minutes
The number of miles increasing each hour is 16, 16 times 4 is 64, and to get to 76, you add an extra 3/4 of an hour, which is 45 minutes.
The distance between Antony and Lily will be 76 miles after 4.75 hours.
What is Speed?Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.
Speed is a scalar quantity as it only has magnitude and no direction.
Given that,
Antony and Lily started moving in opposite directions from the same point at the same time.
Speed of Antony = 12 mph
Speed of Lily = 4 mph
Let x be the distance traveled by Antony.
Then the distance traveled by Lily = 76 - x
Time will be the same, let it be t.
t = x /12 and t = (76 - x) / 4
x/12 = (76 - x) / 4
4x = 12 (76 - x)
4x + 12x = 912
16x = 912
x = 57
t = 57/12 = 4.75 hours

A triangular courtyard has a perimeter of 120 meters. The lengths of two sides are 30 meters and 50 meters. How long is the third side?
Answers
Answer:
the third side is 40 m long
Step-by-step explanation:
The perimeter of the triangle is the sum of its three sides, and they give you what that value in meters is (120 m)
Your are given the length of two of them: 30 m and 50 m, and need to find the third one (let's call it "x" for this unknown side)
Now set the following equation:
Perimeter = side 1 + side 2 + side 3 --> replace these with the info you know
120 m = 30 m + 50 m + x --> add 30 m and 50 m obtaining 80 m
120 m = 80 m + x --> now solve for x (isolate the x on one side) by subtracting 80 m from both sides
120 m - 80 m = x --> perform the subtraction 120 m - 80 m = 40 m
40 m = x
Which tells us that the third unknown side has a length of 40 m
Answer:
The third side is 40 meters long
Step-by-step explanation:
From the question, we were told that a triangular courtyard has a perimeter of 120 meters, we are to find the length of the third side if the other two sides are 30 and 50 meters.
First, we need to know that perimeter is the distance around a polygon.
Let the third side = side c, let the two sides be side A and side B
Perimeter = side A + side B + side c
side A = 30 meters
side B = 50 meters
side C = ?
Perimeter = 120 meters
We can now proceed to insert the values in the equation above
Perimeter = side A + side B + side c
120 = 30 + 50 + side c
120 = 80 + side c
Subtract 80 from both-side of the equation
120 - 80 = 80 - 80 + side c
40 = side c
side c = 40 meters
Therefore, the third side is 40 meters long

So, an equation can formed which is as follows:
3s + c = 38 ---- eqn 1
On the Second day of ticket sales the school sold 3 senior citizen and 2 child ticket for a total of $52
3s + 2c = 52 ---- eqn 2
Multiply eqn 1 by 2
6s + 2c = 76 ---- eqn 3
Now subtract eqn 2 from eqn 2
6s + 2c = 76
(-) 3s + 2c = 52
---------------------
3s = 24
s = 8
Plug in s = 8 in eqn 2,
24 + 2c = 52
2c = 28
c = 14
Hence, the price of senior citizen ticket is $8 and that of children ticket is $14

At a sale this week, a sofa is being sold for $244.80. This is a 64% Discount from the original price. What is the original price?
Answers
Answer:
680$
Step-by-step explanation:
If this is a 64% discount, the price 244.80 is 36% of the original price
244.8 = 36% -Divide by 36 on both sides
6.8 = 1% - Times by a hundred
680 = 100%
The original price is 680$
To find the original price of the sofa given a 64% discount, divide the sale price by the discount percentage and subtract it from 100%.
Explanation:To find the original price, we need to determine what the discount percentage represents in terms of the original price. Since the sale price is 64% of the original price, the discount is 100% - 64% = 36%. Let's represent the original price as x:
36% of x = $ 244.80
To solve this equation, we can convert 36% to the decimal form by dividing it by 100: 36/100 = 0.36. Now we can solve for x:
0.36x = $ 244.80
Dividing both sides of the equation by 0.36, we get:
x = $ 244.80 / 0.36 = $ 680
Therefore, the original price of the sofa was $ 680.

Write a quadratic function to model the graph to the right
Answers
Answer:
y = x² + 2x + 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 1, 4), thus
y = a(x + 1)² + 4
To find a substitute (0, 5) a point on the graph into the equation
5 = a(0 + 1)² + 4
5 = a + 4 ( subtract 4 from both sides )
a = 1, thus
y = (x + 1)² + 4 ← expand and simplify
= x² + 2x + 1 + 4
= x² + 2x + 5
The quadratic function to model the graph to the right is f(x) = x² + 2x + 5.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
The graph of the quadratic function is given in the picture.
As we know,
(y - h)² = 4a(x - k)
(h, k) is the vertex of the parabola:
Or
y = a(x - h)² + k
From the graph:
Here the vertex = (- 1, 4)
y = a(x + 1)² + 4
Plug x = 0, and y = 5 to find the value of a
5 = a(0 + 1)² + 4
a = 1
y = (x + 1)² + 4
f(x) = x² + 2x + 5
Thus, the quadratic function to model the graph to the right is f(x) = x² + 2x + 5.
