Answer:

the equation is

y = 0.75x

And, the constant of proportionality is 0.75

Step-by-step explanation:

The computation is shown below:

Given that

4y = 3x

And,

12y = 9x

Here the equation that represent proportional relationship is

4y = 3x

Divide both sides by 4

y = 3x ÷ 4

Now

12y = 9x

divides both sides by 12

y = 9 ÷ 12x

y = 3 ÷ 4x

y = 0.75x

so the equation is

y = 0.75x

And, the constant of proportionality is 0.75

If the point (a,3) lies on the graph of the equation 5x + y = 8 then a =?

Contact [7]

Answer:

a = 1

Step-by-step explanation:

Given the point (a, 3) is on the line: 5x + y = 8.

Any point on the line satisfies the equation.

So, (a, 3) should satisfy the equation 5x + y = 8

Substituting x = a and y = 3, we get:

5(a) + 3 = 8

$\implies 5a = 5$

⇒ a = 1

Therefore, (1, 3) is the point on the line.

Negative 4 equals r/20 minus 5

levacccp [35]

Answer: r = - 20

Step-by-step explanation:

$-4 = \frac{r}{20} - 5$

$\frac{r}{20} = 4-5$

$\frac{r}{20}=-1$

$\frac{r}{20}*20 = -1 * 20$

$r = -20$

When you have two side lengths of 2in and 4.5in What is the other side length?

nika2105 [10]

Answer:

The solution for the other side length is the interval

(2.5,6.5)

Step-by-step explanation:

I will assume that is a triangle

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ---> the measure of the third side

Applying the Triangle Inequality Theorem

1) $2+4.5 > x$

$6.5 > x$

Rewrite

$x < 6.5\ in$

2) $2+x> 4.5$

$x> 2.5\ in$

therefore

The solution for the other side length is the interval

(2.5,6.5)
