Answer:

The constant of proportionality is equal to 2.5.

Step-by-step explanation:

The given equation is .

Now, let's assume y is proportional to x.

Mathematically, it can be written as,

Now, to eliminate the sign of proportionality by equal to, it is required to introduce a constant term. It can be represented as,

Now, compare the given equation with the above equation,

The above comparison concludes that the constant of proportionality is equal to 2.5.

(Angle/triangle problem 25points)<br> What is the value of X?

Serhud [2]

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the triangle and equate to 180, that is

10x - 4 + 8x + 3 + 91 = 180

18x + 90 = 180 ( subtract 90 from both sides )

18x = 90 ( divide both sides by 18 )

x = 5

ziro4ka [17]

Answer:

$(a)\ u \le -4$

$(b)\ u =\{-\infty,.....,-6,-5,-4\}$

Step-by-step explanation:

Given

$-u \ge 4$

Solving (a): An equivalent inequality

We have:

$-u \ge 4$

Multiply both sides by -1 (this changes the inequality)

$-u*-1 \le 4 * -1$

$u \le -4$

Solving (b): Values of u from least to greatest

$u \le -4$ implies that u ends at -4, starting from negative infinity

So, the list is:

$u =\{-\infty,.....,-6,-5,-4\}$
