Select all of the following graphs which represent y as a function of x

Elden [556K]

A, B, D, and E are correct.

What makes these a function and the others not is that for each x value, there is only one y value. For C, for example, there are multiple y values for the x value of -2. The same goes for F.

!!!PLEASE HELP I'LL GIVE BRAINLIEST AND 30 POINTS!!!

If two events are independent, then P(A and B) = P(A) x P(B).

In your situation, you need to solve 0.185 = 0.25 x P(B).

Can you take it from there?

the product of 7 and a number increased by 3 is equal to twice the number subtracted from 39 find the number

Vanyuwa [196]

Say x is the number

7x +3 = 39 -2x
Add 2x to each side
9x +3 =39
Subtract 3 from each side
9x =36
Divide by 9 on each side
x=4

Hope this helped

Let y = safe load in pounds and x = length in feet of a horizontal beam. A constant of proportionality k exists such that y=k/x

Contact [7]

Answer:

Option c. 30,000

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

y ----> safe load in pounds

x ----> length in feet of a horizontal beam

we have

For $x=15\ feet, y=2,000\ pounds$

Remember that

$k=y*x$

substitute

$k=2,000*15=30,000$
