Step-by-step explanation:

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) .

Step-by-step explanation:

The number of teaspoons of strawberry syrup per ounce of milk this recipe use is 0.375 and the number of ounces of milk needed per teaspoon of strawberry syrup is 2.67

The given parameters are

Teaspoons = 3

Ounces of milk = 8

The number of teaspoons of strawberry syrup per ounce of milk this recipe use is calculated as

Rate = Teaspoons/Ounces of milk

So, we have

Rate = 3/8

Evaluate

Rate = 0.375

The number of ounces of milk needed per teaspoon of strawberry syrup is

Rate = Ounces of milk/Teaspoons

So, we have

Rate = 8/3

Evaluate

Rate = 2.67

Hence, the number of teaspoons of strawberry syrup per ounce of milk this recipe use is 0.375 and the number of ounces of milk needed per teaspoon of strawberry syrup is 2.67

The formula for the temperature in ºC is:

As shown in the problem, the rule is as follows:

F(C) = 9C/5 + 32.

We want to find the temperature in Celsius given the Fahrenheit temperature, hence we have to solve for C the above formula, hence:

9C/5 = F - 32

9C = 5(F - 32)

C = 5/9(F - 32).

Answer:

It would be at the coordinates 4,5

Step-by-step explanation:

The sequence  1,4,9,16, . . . is neither an arithmetic nor a geometric sequence. In fact, it is a quadratic sequence. The next two terms are: 25 and 36

Given a sequence:

  1,4,9,16, . . . .

To determine whether the sequence is an arithmetic, geometric, or neither, we need to check the relation between two consecutive terms.

Arithmetic sequence:

   a(n) = a(n-1) + d

or a(n) - a(n-1) = d  for all n

where d is a constant and is usually called common difference.

Geometric sequence:

   a(n) = a(n -1) . r

or a(n)/a(n-1) = r, for all n

In the given sequence:

a(1) = 1

a(2) = 4

a(3) = 9

a(4) = 16

Check the difference:

a(2) - a(1) = 4 - 1 = 3

a(3) - a(2) = 9 - 4 = 5

Since the difference between 2 consecutive sequence is not a constant, then the sequence is not an arithmetic one.

Check the ratio:

a(2)/a(1) = 4

a(3)/a(2) = 9/4

Since the ratio of 2 consecutive sequence is not a constant, then the sequence is not a geometric one.

Thus the given sequence is neither an arithmetic, nor a geometric sequence. In fact, it is a quadratic sequence. Notice that:

a(n) = n²

Hence, the next two terms are: 25 and 36

Based on the calculations, the coordinates of the y-intercept are (0, -9).

In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0). Similarly, the x-intercept refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given parameters into the formula, we have;

Slope, m = (-4.5 - 3)/(-3 + 8)

Slope, m = -7.5/5

Slope, m = -1.5.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

At point (-8, 3), we have:

y - 3 = -1.5(x + 8)

y - 3 = -1.5x - 12

y = -1.5x - 12 + 3

y = -1.5x - 9

The sum of the first ten terms of any Fibonacci-like sequence is 88.

The Fibonacci numbers, sometimes known as Fn in mathematics, are a series. Each number in the Fibonacci sequence is composed of the sum of the two numbers before it. Typically, the sequence begins with 0 and 1.

means

0+1 = 1

1+1 = 2

1+2 = 3

2+3 = 5,like this.

The Fibonacci sequence includes the numbers 0, 1, 1, 2, 3, 5, 8, 13, 21 and so on.

Sum = 0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 = 88 is what we get when we add up the numbers in the series.

Answer:

subtract 4from each side

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

Answer:  shift 2 units right, and 4 units down

==================================================

Explanation:

The x+2 means to shift the point 2 units to the right.

For instance, the point (5,13) moves to (7,13) after adding 2 to the x coordinate.

The y-4 means to shift the point 4 units down. Example: (10,8) moves to (10,4) after subtracting 4 from the y coordinate.

Overall, (x,y)→(x+2,y-4) means "shift 2 units right, and 4 units down"

------------

Example:

Let's apply the rule to the point (1, 7)

(x,y)→(x+2,y-4)

(1,7)→(1+2,7-4)

(1,7)→(3,3)

The slope of the line containing (4,2) and (4,-3) is 1.

The slope of a straight line can be written as follows,

m = ( [tex]y_{2} - y_{1}[/tex])/([tex]x_{2} - x_{1}[/tex])                 equation1

The line is containing the points (5,-1) and (2,-4). So, we can write

[tex]y_{2}[/tex] = -4 , [tex]y_{1}[/tex] = -1 , [tex]x_{1}[/tex] = 5 , and [tex]x_{2}[/tex] = 2 .

On substituting the values of variables in equation1, we will get

m = (-4-(-1))/(2-5) = (-3/-3) = 1.

As the slope of a line is 1 , so we can conclude that the given line is a straight line.

Here,

m = the slope of the line

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex]  ) are the first coordinates.

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex]  )are the second coordinates.

The slope of the line containing (5 , -1) and ( 2 , -4 ) is 1.

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.

The number 1/3 as a percentage is 33.33 %.

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The percent sign, %, is frequently used to indicate it. There is no unit of measurement for a percentage. It is a dimensionless number (pure number).

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.

Let the number be 1/3 then

1/3 = 0.3333

To find percentage multiply it by 100, we get

So, 0.3333 × 100 = 33.33 %

The conjecture is always true, two right angles are always supplementary.

A pair of angles are supplementary only when the sum of those angles equals to 180°. In such a case each angle is said to be the supplement of another.

In case of parallel lines  and a transversal two co-interior angles are supplementary. The opposite angles of a cyclic quadrilateral are supplementary angles .

For two angles to be supplementary only the sum of the angles matter and they should always be 180°.

The numerical value of right angle is 90° .

Therefore the sum of two right angles will be 90°+ 90° = 180°

So the conjecture which states that two right angles are supplementary will always stand as the sum of two 90°s is always 180°.
