The diagram shows two parallel lines cut by a transversal. One angle measure is shown.
Two lines that do not intersect. A third line intersects with both lines.
Find the values of a, b, c, d, e, f, and g. Do not include any labels or degree symbols.
a=
b=
c=
d=
e=
f=
g=
Answer:
See below
Step-by-step explanation:
a + 54° = 180° [Angles on a straight line]
a = 180 - 54
a = 126°
a + b = 180 [Angles on a straight line add up to 180 degrees]
126 + b = 180
b = 180 - 126
b = 54°
c° = a° [Vertically opposite angles are equal]
c° = 126°
d = 54° [Corresponding angles are equal]
e = a [Corresponding angles are equal]
e = 126°
f = b [Corresponding angles are equal]
f = 54°
g = c [Corresponding angles]
g = 126°

Marlena bought a car in 2010. As years passed, the value of the car decrease linearly, as shown in the table. What was the purchase price of the car in 2010, and how much does it decrease each year?
Answer:
B
Step-by-step explanation:
Difference between value as the years pass, ($22,050-$19,600 = $2,450)
To find purchase price: $22, 050 + $2,450 = $24,500

A shipping container will be used to transport several 150-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 28000
kilograms. Other shipments weighing 10300 kilograms have already been loaded into
the container. Write and solve an inequality which can be used to determine x, the
number of 150-kilogram crates that can be loaded into the shipping container.
A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 6400 kilograms have already been loaded into the container.
Answer:
[tex]x<=118[/tex]
Step-by-step explanation:
We already have [tex]10300[/tex] kilograms, we will add [tex]x*150[/tex] kilograms, and we need it to be less than or equal to [tex]28000[/tex].
So, the inequality is [tex]150x+10300<=28000[/tex].
We can subtract [tex]10300[/tex] from both sides to get [tex]150x<=17700[/tex].
We then lastly divide by [tex]150[/tex] on both sides to get [tex]x<=118[/tex].
So, the answer is [tex]\boxed{x<=118}[/tex] and we're done!
Point L is located (5,-5) on the coordinate plane. Point L is reflected over y axis to create point L'. What ordered pair describes the location of L'?
Answer:
[tex](-5, -5)[/tex]
Step-by-step explanation:
To reflect a point over the y-axis is the same as flipping the sign of the x-value of the point.
So, point L reflect is [tex](-(5)), -5)=\boxed{(-5, -5)}[/tex].

The Mad Hatter is ordering cups from Teacups
Limited, for his tea party. The Tescups, Limited catalog
prices cups according to the number of cups ardered. For
orders of 20 or fewer cups, the price is $1.40 per cup plus
$12 shipping and handling on the order. For orders of
more than 20 cups, the price is $1.10 per cup plus $15
shipping and handling
a) Create a piece wise function to describe the
price of cups
b) How much will it cost the Mad Hatter if he orders
20 cups?
a) The piecewise function is:
[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
[tex]C(n) = 15 + 1.1n, n > 20[/tex]
b) Applying the piecewise function, it is found that it will cost $40.
A piecewise function is a function that has different definitions based on the input.
Item a:
20 or fewer cups, fixed cost of $12 for shipping plus $1.40 per cup. Thus, the first definition of the function for the cost of n cups is:[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
For more than 20 cups, price of $1.1 per cup plus a shipping and handling fee of $15. Then:[tex]C(n) = 15 + 1.1n, n > 20[/tex]
Then, the piece-wise function is:
[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
[tex]C(n) = 15 + 1.1n, n > 20[/tex]
Item b:
The cost of 20 cups is C(20).It is the first definition, which is valid for [tex]n \leq 20[/tex].Then:
[tex]C(20) = 12 + 1.4(20) = 12 + 28 = 40[/tex]
It will cost $40.

7x398 thats the questioni need you to answer hahah
Answer:
2,786
Step-by-step explanation:
You can make this easier by taking the expanded form of 398:
300 + 90 + 8
7 x 300 = 2100
7 x 90 = 630
7 x 8 = 56
Then add all these values together:
2100 + 630 + 56 = 2,786
5x+3y=-16
-10x-3y=11
Find the solution
Answer: x = 3.2 + 0.6y
Step-by-step explanation: Simplifying
5x + -3y = 16
Solving
5x + -3y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 16 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 16 + 3y
5x = 16 + 3y
Divide each side by '5'.
x = 3.2 + 0.6y
Simplifying
x = 3.2 + 0.6y
Who can solve these three ??
Answer:
1) x = 9
2) y = 16
3) y = -1
Step-by-step explanation:
Do PEMDAS in reverse.
For every equation, your goal is to seperate the variable (x,y, or whatever letter) by itself.
1) 2x-7 = 11
Add 7 to both sides.
2x = 18
Divide both sides by 2.
x = 9
2) [tex]\frac{3}{4}y = 12[/tex]
Divide both sides by 3/4 (which turns into multiplying by 4/3).
Left side
[tex]\frac{3}{4}x * \frac{4}{3}\\\\\frac{3}{4}x * \frac{4}{3} = \frac{3*4}{4*3}x\\1x\\x[/tex]
Right side
[tex]12*\frac{4}{3}\\\\\frac{12}{1} *\frac{4}{3}\\\\ \frac{12}{1} *\frac{4}{3} = \frac{12*4}{1*3}\\\\\frac{48}{3} \\16[/tex]
3) 9(y+3) = 18
Remember do PEMDAS in reverse.
Divide both sides by 9.
y+3 = 2
Subtract both sides by 3.
y = -1
