What is the value of x?
daser333 [38]

Answer:

x=22.5

Step-by-step explanation:

BM||DT

Using Intercept theorem/Intercept theorem

\frac{6}{6+15} =\frac{9}{9+x}

6(9+x)=9*21

54+6x=189

6x=135

x=22.5

At least I think so

Suppose that y is directly proportional to x, and y = 150 when x = 15. What is the constant of proportionality?
galina1969 [7]

Answer:  The required constant of proportionality is 10.

Step-by-step explanation:  Given that y is directly proportional to x, and y = 150 when x = 15.

We are to find the constant of proportionality.

According to the given information, we can write

y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~~~~~~~[\textup{where k is the constsnt of propotionality}].

When y = 150 and x = 15, we get from the above equation that

y=kx\\\\\Rightarrow 150=k\times15\\\\\Rightarrow k=\dfrac{150}{15}\\\\\Rightarrow k=10.

Thus, the required constant of proportionality is 10.

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24?
charle [14.2K]
We may answer the question above by dividing the expression y² - 10x + 24 with the given factor, y - 4. The division would give an answer of y - 6. Thus,

                                <span>y² - 10x + 24 = (y - 4)(y - 6)

The answer is the fourth choice, y - 6.</span>
