Find the size of the final unknown exterior angle in a polygon whose other exterior angles are:
63', 64°, 82°, 49° and 58°
Answer: 44°
Step-by-step explanation:
The sum of the exterior angles of a polygon is 360°
If your polygon has six sides, the final angle will be:
= 360 - (63 + 64 + 82 + 49 + 58)
= 360 - 316
= 44°

Step-by-step explanation:
Penny earns $580 more than half of Karen´s salary. If p represents Penny´s salary, write an expression that represents the amount of money Karen earns in relation to Penny.
Answer:
[tex]\frac{p}{2} + $580[/tex]
Step-by-step explanation:
p = Penny's salary
Karen's salary = $580 more than half of p
We can use the fraction [tex]\frac{p}{2}[/tex] to represent half of p.
Since Karen's salary is $580 more, her salary is $580 + [tex]\frac{p}{2}[/tex] .

y = 3x + 7
y = 3x - 7
y =
x + 2
O y = fx-2
Answer:
y = 3x-7
Step-by-step explanation:
Lines that are parallel have the same slopes.
y = 3x-4 ---> y=mx+b (slope = m=3)
point-slope formula for a line: y - y1 = m(x-x1)
slope=m=3

y - 2 = 3(x-3)
y - 2 = 3x-9

Convert the decimal 0.83 to a fraction, and classify it as either rational or irrational
Answer:
83/100, rational
Step-by-step explanation:
A rational number is a number that ends. Even if it has decimals, the decimals have to end. 0.83 is a rational number because it doesn't continually go on.
To write it into a fraction, the easiest way is to take it out of a hundred, like a percentage.
Answer:
83/100
Rational.
Step-by-step explanation:
0.83 can be converted to a fraction.
83/100
The fraction cannot be simplified further.
It is rational because it can be written in the form p/q, where p and q are whole numbers.

2x + 3y = 6
- 4x + 3y = 12
Answer:
D. [tex]x=-1, y=2\frac{2}{3}[/tex]
Step-by-step explanation:
Solving for x:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
Subtract 6 from both sides
2x-6= -3y
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
Subtract 12 from both sides
-4x-12= -3y
Combine equations:
-4x-12=2x-6
Add 4x to both sides
-12=6x-6
Add 6 to both sides
-6=6x
6x= -6
Divide both sides by 6
x= -1
Solving for y:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
-3y+6=2x
Multiply both sides by -1
3y-6= -2x
Multiply both sides by 2
6y-12= -4x
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
-3y+12= -4x
Combine equations:
6y-12= -3y+12
Add 3y to both sides
9y-12=12
Add 12 to both sides
9y=24
Divide both sides by 9

A Canadian dollar is worth about $0.85 in
Answer:
B) $412 U.S Dollars
Step-by-step explanation:
350 divided by 0.85 = 411.7 and then round
Answer:
d. $298 U.S. dollars
Step-by-step explanation:
$1 Can = $0.85 US
Divide both sides of the equation by $1 Can
1 = ($0.85 US)/($1 Can)
$350 Can * ($0.85 US)/($1 Can) = $297.50 US
Answer: d. $298 U.S. dollars
Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $65. For
one performance, 40 advance tickets and 20 same-day tickets were sold. The total amount paid for the tickets was $1900. What was the price of each kind of
ticket?
Answer:
advance tickets $30.00
same day tickets $35.00
Step-by-step explanation:
1. In this equation, you are trying to find two values so you must use system of equations. Your two equations would be:
40x +20y = 1900
x + y = 65
x represents the price of advance tickets and y represents the price of same day tickets.
2. Solve the equation by performing elimination using multiplication. Multiple one equation by a constant to get two equations that contain opposite terms.
40x + 20y = 1900
-40(x + y = 65) → -40x + -40y = -2600
3. Add the equations, eliminating one variable. (add -40x + -40y = -2600 to 40x + 20y = 1900)
40x + 20y = 1900
+ -40x + -40y = -2600
Results in: -20y = -700
Solve for y by dviding both sides by -20.
y = 35
4. Substitute the solved value into one of the equations and solve for the remaining variable.
x + 35 = 65
Subtract 35 from both sides to solve for x.
x = 30
The advance tickets were $30.00 and the same day tickets were $35.00.
2x − 5y = 16
3x + 2y = 5
can you also explain how you did it. Thanks :)
Answer:
x=3
y=-2
Step-by-step explanation:
2x - 5y = 16
3x + 2y = 5
Solve for x in the first equation.
2x - 5y = 16
2x = 16 + 5y
x = (16 + 5y)/2
x = 8 + 5/2y
Put x as 8 + 5/2y in the second equation and solve for y.
3(8+5/2y) + 2y = 5
24+15/2y + 2y = 5
24 + 19/2y = 5
19/2y = 5-24
19/2y = -19
y = -2
Put y as -2 in the first equation and solve for x.
2x - 5(-2) = 16
2x +10 = 16
2x = 16-10
2x = 6
x = 3

Answer:
A)f(x)=2x-9 and g(x)=(x+9)/(2)
Step-by-step explanation:
f(g(x)) =x for inverses
A)f(x)=2x-9 and g(x)=(x+9)/(2)
2(x+9)/2) -9 = Canceling the 2 x+9 -9 = x inverse

Partial fraction decomposition of 6x/(x-4)(x+2) is 4/(x-4) + 2/(x+2)
What is partial fraction decomposition?In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction is an operation that consists of expressing the fraction as a sum of a polynomial and one or several fractions with a simpler denominator.
Given, expression
6x/(x-4)(x+2)
Creating fraction template using denominator (x-4)(x+2) :
6x/(x-4)(x+2) = A/(x-4) + B/(x+2) ------(1)
Multiplying with (x-4)(x+2) on both sides
6x(x-4)(x+2)/(x-4)(x+2) = A(x-4)(x+2)/(x-4) + B(x-4)(x+2)/(x+2)
6x = A(x+2) + B(x-4)
Roots of the denominator are x = 4, -2
Putting x = 4,
6(4) = A (4+2) + B (4 - 4)
24 = 6A
A = 4
Putting x = -2
6(-2) = A (-2+2) + B (-2 - 4)
-12 = -6B
B = 2
Substituting value of A and B in equation 1
6x/(x-4)(x+2) = 4/(x-4) + 2/(x+2)
Hence,
4/(x-4) + 2/(x+2)
is the partial fraction decomposition of 6x/(x-4)(x+2).
