Is 9-8x=y proportional

andrew-mc [135]

Answer:

No, proportional relations are of the form,

$y = mx$

Step-by-step explanation:

The given equation is

$9 - 8x = y$

This is an equation in the form:

$y = mx + c$

since we can rewrite to get:

$y = - 8x + 9$

This equation has a non-zero y-intercept and does not pass through the origin.

A proportional relation, will have a zero y-intercept and pass through the origin.

Therefore a proportional relation is of the form,

$y = mx$

What is the measure (in radians) of central angle 0 in the circle below? Enter an exact expression.

Makovka662 [10]

Answer:

$\frac{\pi^{c} }{3}$

Step-by-step explanation:

Measure of the length of an arc of a circle is given as:

$l = \frac{ \theta}{2\pi} \times 2\pi r \\ \\ \pi = \frac{ \theta}{2\pi} \times 2\pi \times 3 \\ \\ 3 \theta = \pi^{c} \\ \\ \theta = \frac{\pi^{c} }{3} \\$
