B
None of the above
Answers
The algebraic expression (z+0)+y+0 is equivalent to (z+y) by the identity property of addition.
An algebraic expression is a simple and random combination of constants and variables .
An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).
The identity property of addition states that when a constant number is added to zero the value of the expression remains the same.
Since the absolute value of 0 is nothing so adding or subtracting zero from a constant does not change the value of the constant.
I.e, g+0=0 here the value of g does not change.
Given (z+0)+y+0
We know from the identity property of addition:
z+0=z and y+0=y
Therefore the value of the expression is (z+y) .

Write an equation of the line in point-slope form through each pair of points. (0,0) and (-4,7)
Answers
The general form of a linear equation is y - y1 = m(x - x1). The point-slope form is y = - 1.75x.
What is point-slope form?The general form of a linear equation is y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).
Given: (x1, y1) = (0, 0) and (x2, y2) = (-4, 7)
The point-slope form is given by,
y - y1 = m(x - x1)
m = (y2 - y1)/(x2 - x1)
substitute the values in the above equation, we get
m = (7- 0)/(-4 - 0) = -7/4
The value of m = -7/4.
y = -1.75x
Therefore, the point-slope form is y = - 1.75x

F(x)=|x|+5; horizontal shrink of factor 3
Answers
the horizontally shrunk function by a scale factor K = 3 is modeled by:
g(x) = |3*x| + 5
How to apply a horizontal shrink to a function?
For any function f(x), we define a horizontal shrink or compression by a scale factor K as:
g(x) = f(K*x)
In this case the function is:
f(x) = |x| + 5
And the scale factor is K = 3.
Then we can write the compression as:
g(x) = f(3*x)
Replacing the actual function we will get:
g(x) = f(3*x) = |3*x| + 5
Then the horizontally shrunk function by a scale factor K = 3 is modeled by:
g(x) = |3*x| + 5

What is a pie chart?A pie chart is a type of chart that shows data in a circular graph.
We recognise that the pie's total value is always 100%. It is additionally recognized that a circle has a circumference of 360°. As a result, the sum of all the data equals 360°. Depending on these, there seem to be two main pie chart formulas:
We use the following formula to calculate a percentage of the data set: (Frequency ÷ Total Frequency) × 100We use the following formula to convert the data to degrees: (Given Data ÷ Total value of Data) × 360°On complete rotation of circle forms 360 degrees at the centre.
The total percentage of the all the colours is 100%.
Divide the value of blue by 3.6 because 360 degrees /100 percent = 3.6.
The total percentage of blue shown by the pointer of spinner is 30%.
Probability P (pointer landing on blue) = 30/3.6
Probability P (pointer landing on blue) = 8.333... = 8.4 (approx.)
Therefore, the probability that the pointer lands on the blue is 8.4.

When you adjust one number and change another number in the problem to make a computation easier you use ?
Answers
To make a computation easier, you adjust one number and alter another number in the problem is called compensation.
What is termed as the compensation strategy?Compensation is a multi-digit addition mental math technique that entails adjusting one of the operand to make the equation simpler to solve.
Some students might choose this strategy over left-to-right addition or even the strategy of splitting up the second number.Compensation is an effective method for making calculations easier to solve. More likely, it encourages learners to think about numbers in a variety of ways.Some examples of compensation are-
For example; 29 + 96We can alter the value of 29 to 30 by adding 1; as it is simpler to sum 30.Then, 30 + 96 = 126Now, the added value is then subtracted from obtained addition.126 - 1 = 125Hence, 29 + 96 = 125Thus, this method is used in solving with simpler form.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12

What is scientific notation?Scientific Notation is the expression of a number in the form a x [tex]10^{b}[/tex]. where a is an integer such that 1 ≤ |a| < 10 and b is an integer too.
We have,
Number of stars in our galaxy = 3 x [tex]10^{11}[/tex]

a₁ is the first term of a sequence, r is a common ratio, and d is a common difference. Write the first five terms. a₁=2, r=-2
Answers
The first five terms of a geometric sequence with first term 2 and common ratio (-2) are 2, -4, 8, -16, 32
The given parameters:
a₁ = 2, r = -2
r is the common ratio, hence, the given sequence is a geometric sequence.
In a geometric sequence, the formula for the nth term is given by:
a(n) = a(1) . rⁿ⁻¹
We can also find the terms using recursive formula. The nth term of a geometric sequence is equal to the (n-1)th term times the common ratio, r. Mathematically,
a(n) = a(n -1) . r
Let us start from n = 1
a(1) = 2 (given)
a(2) = a(1) . r = 2 . (-2) = -4
a(3) = a(2) . r = -4 . (-2) = 8
a(4) = a(3) . r = 8 . (-2) = -16
a(5) = a(4) . r = -16 . (-2) = 32

What is the equation of line in slope intercept form ?
The equation of line in slope intercept form is y = mx + c , where m is the slope and c is the y-intercept.
As per the question ;
Line contains points (2,4) and (0,-2)
We know that slope intercept form of line is ;
y = mx + c
∴ (2,4) and (0,-2) must satisfy the equation because the line contains them.
So ,
For x = 2 and y = 4 ;
the equation y = mx + c becomes ;
4 = 2m + c ------ ------ ------ ---- (1)
Also ;
For x = 0 and y = -2 ;
the equation y = mx + c becomes ;
-2 = 0 + c
or
c = -2
Put the value of c in equation 1 ;
i.e.,
4 = 2m - 2
2m = 6
or
m = 3
So ,
the equation of line which contains points (2,4) and (0,-2) will be ;
y = (3 × x) - 2
y = 3x -2
