Answer:
1 solution
Step-by-step explanation:
A system of two equations can be classified as follows:
1) If the slopes are the same but the y-intercepts are different, the system has no solution.
2) If the slopes are different, the system has one solution.
3) If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions

Which expression is equivalent to 12(2x - 3y + 4)?
Answer:
24x - 36y + 48
Step-by-step explanation:
12 (2x - 3y + 4)
Distribute the term outside of the parenthesis, multiply each term inside the parenthesis by the term outside of the parenthesis.
(12)(2x) - (12)(3y) + (12)(4)

HELP!!! Find the measure of each angle.
Answer:
Step-by-step explanation:
This figure is called a cyclic quadrilateral. The vertices of all sides lie on a circle.
That's property one.
Property 2 is that the opposite angles add to 180 degrees.
6y - 4 + 5y - 3 = 180 is the y angles. Combine like terms.
11y - 7 = 180 Add 7 to both sides.
11y - 7 + 7 = 180 + 7
11y = 187 Divide by 11
y = 187/11
y = 17
H = 17 * 6 - 4
H = 102 - 4
H = 98
F = 5y - 3
F = 5*17 - 3
F = 85 - 3
F = 82
=====================
11x + 8 + 8x + 1 = 180
19x + 9 = 180
19x = 171
x = 171/19
x = 9
E = 9*11 + 8
E = 99+8
E = 107
G = 8*9 + 1
G = 72 + 1
G = 73

A right circular cylinder has a base radius of 6 centimeters and a height of 12 centimeters. What is the volume of this cylinder? A. B. C. D.
Answer: [tex]432\pi \text{ cubic centimeters}[/tex] or [tex]1356.48\text{cubic centimeters}[/tex]
Step-by-step explanation:
Volume of right circular cylinder = [tex]\pi r^2 h[/tex]
Given: Radius = 6 centimeters
Height = 12 centimeters
Then, the volume of this cylinder = [tex]\pi (6)^2 \times (12)= 432\pi \text{ cubic centimeters}[/tex]
Hence, the volume of this cylinder = [tex]432\pi \text{ cubic centimeters}[/tex]
At [tex]\pi=3.14[/tex]
The volume of this cylinder[tex]=432\times3.14=1356.48\text{cubic centimeters}[/tex]

Trust me bro
This is for today someone help me!!!
Answer:
Centre = (2, -3)
radius = 5units
Step-by-step explanation:
The standard form of a circle is expressed as;
x²+y²+2gx+2fy+c = 0
Centre = (-g, -f)
radius r = √g²+f²-c
Given the equation;
x²+y²-4x+6y-12 = 0
Compare
2gx = -4x
2g = -4
g = -2
Similarly;
2fy = 6y
2f = 6
f = 3
Centre = (-(-2), -3)
Centre = (2, -3)
Radius = r = √(-2)²+3²+12
r = √4+9+12
r = √25
r = 5 units

after allowing 15% discount on the price of an article and 13% bat was live and the remaining amount in the price of article becomes 13447 find the market price of an article
Answer:
14000
Explaination:
spwithvat = sp without vat + 13% of sp without vat
let, sp without vat be x.
sp with vat= x + 13% of x.
or, 13447 = x + 13/100 × x
or, 1344700 = 113x
or, x= 1344700/113
x = 11900
Let, mp be y.
sp with vat = mp - 15% of mp
or, 11900 = y - 15/100 × y
or, 1190000 = 85y
or, y= 1190000/85
y= 14000
An encyclopedia has 30 volumes. The total weight of these volumes is 71 and 1/4 pounds. Find the average weight of a volume
Answer:
2.375
Step-by-step explanation:
An encyclopedia has 30 volumes. The total weight of these volumes is 71 and 1/4 pounds. The average weight of a volume is 2.375.
What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called the average of the values of the considered data set.
It serves as the predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.

Zane and his favorite geometry student, , have just set sail for a day of fun on lake Erie. A spring squall quickly forms and catches you off guard, leaving you adrift on the lake. Zane suddenly discovers he has an irrational fear of water and is reduced to hugging the mast. You hear Sherman barking from the top of a lighthouse to help guide you to shore. In order to save Zane and yourself, you must calculate how far away you are from this lighthouse. Using a range finder, you expertly measure the distance from the sailboat to the top of the lighthouse at 350 yards.
angle B is 40 degrees.
(a) Based on the above information, find the distance across the water from the sailboat to the island
where the lighthouse is standing. You can only use trigonometry to solve. You must show all work for
credit. Round your answer to the nearest whole number if needed.
(b)Calculate the height of the lighthouse. You can only use trigonometry or Pythagorean Theorem to
solve.
Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.
_________________________________________________________
According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).
Θ = 40hyoptenuse = 350adjacent = xcosine40 = x/350
[multiply both sides by 350]
350 · cosine40 = x
[put calculator in degree mode]
x ≈ 268 yards
So, the distance across the water from sailboat to the island is 268 yards.
_________________________________________________________
Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).
a^2 + b^2 = c^2
a = ? (opposite or height)b = 268 (adjacent)c = 350 (hypotenuse)a^2 + (268)^2 = (350)^2
a^2 + 71824 = 122500
a^2 = 122500 - 71824
a^2 = 50676
[square both sides]
[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]
a = [tex]\sqrt{50676}[/tex]
a ≈ 225
So, the height, opposite, of the lighthouse is 225 yards.

The central angle of arc ST is 70 degrees. What is the measure of an inscribed
angle whose endpoints are points S and T?
Answer:
35
Step-by-step explanation:
The measure of an inscribed angle whose endpoints are points S and T will be 35°.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
The central angle of arc ST is 70°.
The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have
Inscribed angle = 70° / 2
Inscribed angle = 35°
The measure of an inscribed angle whose endpoints are points S and T will be 35°.
