The average rate at which Mr. Blade types is 30 words per minute.
Average or mean is a measure of central tendency where it defines the central number of a data set.
Average is calculated by dividing the total sum of the values of the dat set divided by the frequency or the number of data in the set.
Mr. Adi takes 9 minutes.
The average rate of Mr. Adi is 40 words per minute.
So in 9 minutes he writes 40 × 9 = 360 words in total.
Mr. Blade typed the same number of words.
he took 12 minutes to type it.
So average rate = total words typed ÷ time taken (in minutes)
Average rate= 360 ÷ 12 =30 words per minute.
Hence Mr. Blade writes at the average rate of 30 words per minute.

The grid above shows the graph of the parent function f(x) = | x | and a translated functions graph.
Write the equation for the translated graph.
Please Hurry, I will give brainliest!
By using the principles of translation, the following equation can be derived for the graph of the translated text:
g(x) = |x + 2| + 1.
What is a translation?According to operations like multiplication or sum/subtraction either in its range (including values of y) or in its domain, a translation is represented by a change in the function graph (involving values of x).
Examples include shifts to the left, right, or bottom; compression or stretching along the vertical or horizontal axis; reflections across the x or y axes; and rotations of a degree measured around the origin.
From the graph, we have that the parent function was:
Shifted left 2 units, hence x -> x + 2.
Shifted up 1 unit, hence y -> y + 1.
Hence, considering the parent function f(x) = |x|, the equation for the translated graph is given by:
g(x) = |x + 2| + 1.

Use PEMDAS to determine order of operations in a mathematical expression
The order of operations is
P = parentheses
E = exponent
M = multiplication
D == division
A = addition
S = subtraction
Note that multiplication and division have the same priority and we go from left to right that case. Because it does not affect the answer.
So 12 ÷ 4 x 6 = 12 x 6 ÷ 4
Same for addition and subtraction - same priority
Using PEMDAS
(9 - 1) is executed first giving 8
The expression becomes 8 + 8 ÷ 4
Next division is performed so 8 ÷ 4 is executed giving 2 as the answer
Finally 8 + 2 is executed giving 10

17 + x = 15
pls help
Answer:
x = -2
Step-by-step explanation:
The equation is,
→ 17 + x = 15
Now the value of x will be,
→ 17 + x = 15
→ x = 15 - 17
→ [ x = -2 ]
Hence, the value of x is -2.
Step-by-step explanation:
17+x=15
17+x-17=15-17
x=-2
Solve for x to the nearest tenth.
Applying the Pythagorean Theorem, the value of x to the nearest tenth is: 4.5 units.
What is the Pythagorean Theorem?If c represents the length of the longest side (hypotenuse) of a right triangle, and a and b are the lengths of the other smaller legs of the right triangle, the Pythagorean Theorem states that:
c = √(a² + b²).
In the diagram given, we have a right triangle that is a part of the given shape. Where:
Hypotenuse = c = x
a = 4 units
b = 5 - 3 = 2 units
Plug in the values
x = √(4² + 2²)
x = √(16 + 4)
x = √20
x ≈ 4.5 units (nearest tenth)
Thus, applying the Pythagorean Theorem, the value of x to the nearest tenth is: 4.5 units.

Triangle ABC with vertices A(–4, –4), B(–1, –2), C(3, –1) is rotated 180° about the origin. What are the coordinates of triangle A′B′C′?
Answer:
A(4, 4), B(1, 2), C(-3, 1)
Step-by-step explanation:
Because the triangle is rotated 180° about the origin you are just rotating it 2 quadrants, the size stays the same.
The rule for rotating 180° is if (x, y) is rotating 180° then the new position is (-x, -y).
So:
A(-4, -4), which then becomes B(-(-4), -(-4) ) = B(4, 4)
B(–1, –2) which becomes B(-(–1), –(-2) ) = B(1, 2)
C(3, –1) which becomes C(-3, –(-1) ) = C(-3, 1)

How to identify each of the angle measures?The angle measures are given as:
35° 91° 65° 28°
As a general rule:
Angles that are less than 90 degrees are acute angles
This means that
The angles 35° 65° and 28° are acute angles
Also, we have
Angles that are between 90 degrees and 180 degrees are obtuse angles
This means that
The angle 91° is an obtuse angle
