The equation has no solution if the blank is filled with 5y, so option c is correct.

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign. It shows that the expressions printed on the left and right sides have an equal relationship.

Given equation:

5y + 9 = _

Use the hit and trial method and put the value zero,

5y + 9 = 0

y = -9 / 5

So the equation has a solution,

Again put

5y + 9 = 5y

9 = 0, which is not possible

Therefore, the equation has no solution if we fill the blank with 5y.

Answer:

y = (2/3)x - 4

Step-by-step explanation:

To find the equation of the line in slope-intercept form given a table of values, you will need to calculate the slope of the line and the y-intercept. The slope of a line is a measure of its steepness, and it is calculated as the rise (change in y-values) divided by the run (change in x-values) between two points on the line. The y-intercept is the point at which the line crosses the y-axis.

Given the table x: 9, 3, -3, -9 and y: 2, -2, -6, -10, you can use any two points to calculate the slope. For example, you could use the points (9, 2) and (3, -2) to calculate the slope:

slope = (y2 - y1) / (x2 - x1) = (-2 - 2) / (3 - 9) = -4 / -6 = 2/3

To find the y-intercept, you can use the slope and one of the points from the table to substitute into the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

Using the slope and the point (9, 2), you can solve for b:

y = mx + b

2 = (2/3) * 9 + b

2 = 6 + b

b = -4

Therefore, the equation of the line in slope-intercept form is y = (2/3)x - 4.

To answer the other questions, you can use this equation to determine the y-value for a given x-value or the x-value for a given y-value. You can also use the equation to graph the line on the coordinate plane.

"In a relation r, for every instance of a, that value of a uniquely determines the value of b then a primary dependency exists in the relation.

Relation:

In math relation means the relationship between sets of values of ordered pairs.

Given,

Here we need to find if for every valid instance of a, that value of a uniquely determines the value of b in the relation.

As per the definition of relation, for every relation has two set of data ad each of the element in one set is uniquely refers the other one's element.

The expression for the exact number of inches in 1 centimeter is 2.54/2.54 cm = 1/2.54 in and the number of inches is 0.39

From the question, we have the following parameters that can be used in our computation:

1 inch = 2.54 centimeters and 1 centimeter = 0.39 inch.

To calculate the number of inches expression, we make use of the following equation

1 inch = 2.54 centimeters

Divide both sides of the equation by 2.54

So, we have the following representation

1/2.54 inch = 2.54/2.54 centimeters

Rewrite the expression as

2.54/2.54 centimeters = 1/2.54 inch

So, we have

2.54/2.54 cm = 1/2.54 in

So, the expression is 2.54/2.54 cm = 1/2.54 in

In (a), we have'

Step-by-step explanation:

The function  [tex]f(x)=mx+b[/tex] , is the equation of a line given in slope-intercept form. Where m is the slope of the line and b is the y-intercept of the line. If you were to change the value of m, while keeping the value of b the same, that would result in a rotation. If you were to change the value of b, while keeping the value of m the same, that would result in a translation (specifically a vertical translation).

Evan's error was that he subtracted [tex]-2\frac{1}{2}[/tex] from 4, and thus he got          [tex]6\frac{1}{2}[/tex].  On adding he would be getting  [tex]1\frac{1}{2}[/tex]

It is given that Evan added [tex]-2\frac{1}{2}[/tex] and 4 but got [tex]6\frac{1}{2}[/tex]

The mistake that Evan did was instead of adding, he substracted [tex]-2\frac{1}{2}[/tex] from 4, and thus he got          [tex]6\frac{1}{2}[/tex]. This is because

4 -  [tex]-2\frac{1}{2}[/tex]

= [tex]1\frac{1}{2}[/tex]

Evan's error was that he subtracted [tex]-2\frac{1}{2}[/tex] from 4, and thus he got          [tex]6\frac{1}{2}[/tex].  On adding he would be getting  [tex]1\frac{1}{2}[/tex]

The degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.

What is the quotient?

The number we obtain when we divide one number by another is the quotient. For example, in 8 ÷ 4 = 2; here, the result of the division is 2, so it is the quotient. 8 is the dividend and 4 is the divisor.

To find the quotient and remainder when dividing 8x³ +16x² + 12x+13 by 2x+2, we can use polynomial long division.

First, we divide the leading coefficient of the dividend (8x³) by the leading coefficient of the divisor (2x). This gives us a quotient of 4x². We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the first term of the remainder:

8x³ +16x² + 12x + 13

(2x+2)(4x²)

8x³ - 8x³ -8x² -8x² +12x+13

This leaves us with 12x+13 as the first term of the remainder.

Next, we bring down the next term of the dividend (16x²) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 8x. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the next term of the remainder:

12x+13

(2x+2)(8x)

12x+13 - 16x² - 16x

-4x² -4x

This leaves us with -4x² -4x as the next term of the remainder.

Finally, we bring down the last term of the dividend (12x) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 6. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the final term of the remainder:

-4x² -4x

(2x+2)(6)

-4x² -4x -12x -12

-16x² -16x

This leaves us with -16x² -16x as the final term of the remainder.

Hence, the degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.

We can write the result of the division as:

(8x³ + 16x² + 12x + 13) ÷ (2x+2) = (4x² + 8x + 6) + (-16x² -16x)/(2x+2)

The answer for the first shape would be 24cm^2.

The answer for the second shape would be 20cm^2.

The answer for the third shape would be 30cm^2. "30".

What are Shapes?

A shape in geometry can be characterized as an object's form, outline, outer border, or outer surface.

The first shape seems to be scaling up. From 3cm to 12cm. So for this you need to multiply. Using the formula that I gave you last time.

3cm times ___ = 12cm. 4 fits in there,

therefore 6cm^2 times 4 = 24cm^2.

The answer for the first one would be 24cm^2. "24" in the blank.

The second shape seems to be scaling down. From 16cm to 8cm. So for this you need to divide.

16cm divided by ___ = 8cm. 2 fits in there,

therefore 40cm^2 divided 2 = 20cm^2.

The answer for the second one would be 20cm^2. "20" in the blank.

The third shape seems to be scaling up.

From 3cm to 4.5cm.

So for this you need to multiply. 3cm times ___ = 4.5cm.

Now since we're dealing with decimals, not whole numbers this time you can't really use guess and check as efficiently. So you do the opposite operation, which in this case the opposite of multiplication is division.

You take 3cm (the original shape's number) and divide it into 4.5cm. So 4.5cm divided by 3cm = 1.5. 1.5 fits in there,

therefore 20cm^2 times 1.5 = 30cm^2.

The answer for the third one would be 30cm^2. "30" in the blank.

When two quantities or variables are linearly related in mathematics, the term "proportional" is used. Both quantities increase by two times when one increases by two. Each variable decreases in proportion to the other when it falls to 1/100th of its previous value.

We must determine the ratio of the two quantities for each value supplied in order to determine if two quantities are proportionate. The proportionate link between them is evident if their proportions are equal. Their connection is not proportionate if all the ratios are out of balance.

What is equivalent expression?

Expressions that function identically despite having different appearances are called equivalent expressions. If two algebraic expressions are equivalent, then when we enter the same value(s) for the variable, the two expressions have the same value (s).

Consider, the given expression

8x + 4y  and 4(2x + 1)

Consider, 4(2x + 1)

Simplifying this,

4(2x + 1) = 8x + 4

8x + 4 is different from 8x + 4y.

Hence, 8x + 4y is not equivalent to 8x + 4.

Now consider, 8x + 4y = 6x(4y + 2x)

Simplifying this

8x + 4y = 24xy + 12x^2

⇒ 8x + 4y = 6x(4y + 2x) is not equivalent.

Now consider, 8x + 4y = 8(x + 4y)

(8x + 4y) = 8x + 32y

⇒ 8x + 4y = 8(x + 4y is not equivalent.

Now consider,  8x + 4y = 4(2x + y)

8x + 4y = 8x + 4y

⇒ 8x + 4y = 4(2x + y) is equivalent.
