If y=kx, where k is a constant, and y=24 when x=6, what is the value of y when x=5?A. 6B. 15C. 20D. 23
Marizza181 [45]

First, we will find the value of k

We can do this by sybstituting y=24, x=6 in;

y=kx and then solve for k

24= k(6)

divide both-side of the equation by 6

24/6 = k

4 = k

k=4

Then when x = 5, we will substitute x=5 and k=4 in; y=kx and then solve for y

y= (4)(5)

y = 20

A triangle has sides 42, 4x, and 2x−6. What is the possible range of x? <br><br>? &lt; x &lt; ?
natulia [17]

Answer:

8\ units< x < 18\ units

Step-by-step explanation:

we know that

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

so

Applying the Theorem

case 1) 42+4x > 2x-6

4x-2x > -6-42

2x > -48

x > -24\ units

case 2) 42+(2x-6) >4x

42-6 >4x-2x

36 >2x

18 >x -----> rewrite

x

case 3) 4x+(2x-6) > 42

4x+2x > 42+6

6x > 48

x > 8\ units

therefore

8\ units< x < 18\ units
