Answer:

Yes, but none of the answer choices exactly describe the proportional relationship. The closest choice is A.

Step-by-step explanation:

The form of the equation of a proportional relation is y = kx, where k is the coefficient.

In the given case y =1/2x, where k = 1/2, so it represents proportional relationship.

<u>Answer choices:</u>

A. Yes, because the coefficient of x is positive

- it is yes, but the coefficient can also be negative

B. No, because it is not in the form y=kx

- it is no, as it is in the for of y = kx

C. No, because its graph does not pass through the origin

- no, it doesn't matter if the graph passes through the origin or not

D. Yes, because its graph is a line that passes through the origin

- no as it is not necessary the graph to pass through the origin

What is the equation has intercepts at x(1, 0, 0), y(0, -1,0), and z(0, 0, 2)

bulgar [2K]

In intercept form, the plane that has these intercepts is ...

... x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1

... x/1 + y/(-1) + z/2 = 1

... 2x -2y +z = 2 . . . . . in standard form

Answer fast! I don't understand how to do this. I have a test going on about exponent properties.

qwelly [4]

Answer:

$x^4yz$

Step-by-step explanation:

$\frac{(x^6y^3z^2)}{(x^2y^2z)}$ (This can be simplified, because when you divide expressions with exponents that have the same bases, you can subtract the exponents from the one with the corresponding base)

$\frac{(x^6y^3z^2)}{(x^2y^2z)}$

= $(x^(^6^-^2^)y^(^3^-^2^)z^(^2^-^1^))$ (Simplify)

= $x^4yz$

What transformation has changed the parent function f(x) = log3x to its new appearance shown in the graph below?

irina [24]

Answer: Third option

$f(x) - 2$

Step-by-step explanation:

The function $y=log_3 (x)$ passes through the point (1,0) since the function $y=log_a (x)$ always cuts the x-axis at $x = 1$ .

Then, if the transformed function passes through point (1,-2) then this means that the graph of $y=log_3(x)$ was moved vertically 2 units down.

The transformation that displaces the graphically of a function k units downwards is:

$y = f (x) + k$

Where k is a negative number. In this case $k = -2$

Then the transformation is:

$f(x) -2$

and the transformed function is:

$y = log_3 (x) -2$
