(20a-10) - (12a-3) subtract
Answer:
8a - 7
Step-by-step explanation:
First, subtract 12a from 20a
20a - 12a
= 8a
Now, subtract -3 from -10.
Subtracting a negative number is the same as adding a positive number, so add 3 to -10.
-10 + 3
= -7
Put together 8a and -7
8a - 7
So, the simplified expression is 8a - 7
In AKLM, mZK = 101° and mL = 67º. Which statement about the sides of AKLM
must be true?
LM > MK > KL
LM > KL > MK
O KL > MK > LM
O KL > LM > MK
MK > KL > LM
O MK > LM > KL
Answer:
LM > MK > KL
Step-by-step explanation:
Given: ΔKLM , m∠K = 101° , m∠L = 67°
By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°
By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.
Note the angles:
m∠M = 12° ∴ Side LK = shortest
m∠K = 101° ∴ Side ML = longest
m∠L = 67° ∴ Side KM = in between
∴ LK < KM < ML
A) LM > MK > KL is your answer.

Graph h(x) = -|x- 6| + 3.
Answer: Shift the graph to the right by 6, and up by 3.
Step-by-step explanation: If a number is in parentheses or absolute value lines, use the inverse sign. If it’s outside of the parentheses, move it like normal.
To graph the function h(x) = -|x - 6| + 3, we can follow a step-by-step approach:
Step 1: Determine the key points:
Identify the vertex: The vertex of the absolute value function y = |x| is at (0, 0). In this case, since we have y = -|x - 6| + 3, the vertex is obtained by shifting the vertex (0, 0) horizontally by 6 units to the right and vertically up by 3 units. Therefore, the vertex is at (6, 3).
Find additional points: Choose some x-values on both sides of the vertex to determine corresponding y-values. Let's choose x = 0, 3, 6, and 9.
Step 2: Calculate the y-values:
For x = 0: h(0) = -|0 - 6| + 3 = -|-6| + 3 = -6 + 3 = -3.
For x = 3: h(3) = -|3 - 6| + 3 = -|-3| + 3 = -3 + 3 = 0.
For x = 6: h(6) = -|6 - 6| + 3 = -|0| + 3 = -0 + 3 = 3.
For x = 9: h(9) = -|9 - 6| + 3 = -|3| + 3 = -3 + 3 = 0.
Step 3: Plot the points:
Plot the points (0, -3), (3, 0), (6, 3), and (9, 0) on a coordinate plane.
Step 4: Draw the graph:
Connect the plotted points smoothly. Since we have an absolute value function with a negative sign, the graph will be an upside-down V-shape, opening downwards, with the vertex at (6, 3).
Here's a visual representation of the graph of h(x) = -|x - 6| + 3:
Please note that the graph above is a rough representation and may not be perfectly to scale.

A boat traveled 27 miles in 2 hours at this rate how many miles will the boat travel in1/2 hour
Answer:
The boat would travel 6.75 miles in a 1/2 hour.
Step-by-step explanation:
If the boat travels 27 miles in 2 hours, you would take 27 and divide it by 2 to find out how many miles it travels in 1 hour. (27/2= 13.5 miles). Then you would take 13.5 miles and divide it by 2 again to find how many miles it traveled in 1/2 an hour. (13.5/2 = 6.75 miles).

The area of a circle in terms of pi is 56 pi m². Find the value of the radius. Give your answer as a simplified surd
Answer: 2√14
Step-by-step explanation:
The area of a circle is A = πr², where r is radius. Since the area is 56π, we can divide π from both sides to find r² = 56. The square root of 56 is √56, which can be rewritten to √8×√7. The square root of 8 is equal to 2√2, so the simplified value for radius is 2√2×√7, or 2√14.
Solve for the area of the square.
Answer:
area of square = 10 x 10 = 100 cm²
area of circle = πr² = (3.14)(5²) = 78.5 cm²
area of shaded portion = 100 - 78.5 = 21.5 cm²
Answer:
The area is [tex]21.5 cm^2[/tex](if no need to round)
The area is [tex]22 cm^2[/tex](if need to round to nearest whole number)
Step-by-step explanation:
10 x 10 = 100
5 x 5 x π = 25 π
25 x 3.14 = 78.5
100 - 78.5 = 21.5

Question 21 of 25
Suppose that g(x) = f(x) + 2. Which statement best compares the graph of
g(x) with the graph of f(x)?
A. The graph of g(x) is vertically stretched by a factor of 2.
B. The graph of g(x) is shifted 2 units up.
C. The graph of g(x) is shifted 2 units down.
D. The graph of g(x) is shifted 2 units to the right.
SUBMIT
Answer:
The graph of g(x) is shifted 2 units down
Step-by-step explanation:
Here, we want to get the relationship between g(x) and f(x)
As we can see, we added 2 to the entirety of f(x) to get g(x)
What this simply means is that it is the y-axis we have business with
Adding 2 to the previous y-axis values in f(x) means we are moving upwards to the tune of 2 units to get the y values of g(x)
so what this simply means is that the graph of f(x) is shifted 2 units up
or
the graph of g(x) is shifted 2 units down to get the y-axis values of f(x)
