Answer:

9/15 = 3/5 (simplified)

Step-by-step explanation:

In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:

$\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}$

The adjacent side is the side that makes up the angle but is not the hypotenuse.

I'm assuming the answer box should ask for cos(theta) rather than cos(x).

2w^2-11w=-12 a w=3/2 or 4 b w=1 or 12 c w=1 or 7 d w = 2.5 or 6

dlinn [17]

Hey mate !!
Here's your answer !!

2w^2 - 11w = -12
2w^2 -11w + 12 = 0
2w^2 - 8w - 3w + 12 = 0

2w ( w - 4) -3 ( w - 4) = 0
(2w - 3) ( w - 4) = 0

Hence

2w - 3 = 0
2w = 3
w = 3/2

w - 4 = 0
w = 4

Hence value of w are 4 and 3/2

Hope this helps!!
Cheers!!

Graphing linear equations

ella [17]

Answer:

To ensure uniformity on an exam

To test whether you can distinguish between the two formats

Step-by-step explanation:

Standard form is when a straight line equation is rearranged in the form:

$ax + by = c$

Therefore y=2x+4 in standard form is

$2x - y = - 4$

The slope-intercept form is when a a straight line equation is written in the form:

$y = mx + c$

where m is the slope and c is the y-intercept.

The given equation is

$y = - \frac{1}{2} x - 5$

This is already in slope-intercept form:

The standard form and slope-intercept forms are just formats.

Your instructor may restrict you to leave your answer in one of these formats maybe for uniformity on a test.

You may also decide to rewrite an equation in slope-intercept form, so that you can easily identify the slope and y-intercept easily for graphing purpose.

An equation is shown 27+18 (3+2) What factor is missing from the equation?

yarga [219]

$\mathbb{\pink{\huge{Hello\:Mate!!}}}$

$Answer$

$Equal sign is missing out there.$

$Step-by-step explanation.$

If it is an equation, there must be equal sign present. It means, we are equating something. If there is equal sign, then it can't be an equation.

$Thanks....!$
