Answer:
B
Step-by-step explanation:
14x - 3x + 11 = -22
-11 -11
14x - 3x = -33
11x = -33
/11 /11
x = -3
Answer:
The answer is B. (-7,-2)
Step-by-step explanation:
Multiply the first equation by 7,and multiply the second equation by -6.
7(−3x+6y=9)
−6(5x+7y=−49)
Becomes:
−21x+42y=63
−30x−42y=294
Add these equations to eliminate y:
−51x=357
Then solve−51x=357for x:
−51x=357 Divide both sides by -51
x=-7
Write down an original equation:
−3x+6y=9
Substitute−7forxin−3x+6y=9:
(−3)(−7)+6y=9
6y+21=9(Simplify both sides of the equation)
6y+21+−21=9+−21(Add -21 to both sides)
6y=−12
y=-2
Answer:
Step-by-step explanation:
Given:
Radius of circular mirror, r = 6x
Length of metal frame, l = 18x
Area of square, As = l^2
Area of square = 18x × 18x
= 324 x^2.
Area of circular mirror, Ac = pi × r^2
= π × (6x)^2
= 36π x^2.
The expression for the area of the frame is subtracting the mirror from the metal frame = As - Ac
= 324x^2 - 36πx^2
= 36x2 (9 - π).
The correct order of the radius
.
What is decreasing and increasing order?
A set of data is said to be in descending order, often referred to as decreasing order, when it is arranged from highest to lowest or largest to smallest.
The same concepts apply regardless of the type of information you're working with, whether it's letters, dates, sizes of things or any other group of information like numbers or dates.
For instance, arranging a group of numbers in descending order means doing so from biggest to smallest value.
Ascending order, often known as ascending order of importance, is the exact opposite of declining order.
The order of the items is lowest to highest value. The lowest value is placed first in the order, while the highest value is placed last.
The value of
= 1.732
so
/ 11 = 1.732/11
=1732/11000
The value of
= 3.14
so
/ 24 = 3.14/24
= 314/2400
