Step-by-step explanation:

x and y are roughly in a linear relationship.

when x increases by 2 units, then also y increases by more or less 2 units.

when x increases by 3 units, then also y increases by more or less 3 units.

it is not precise, but a good approximation model.

Find a equation for the slope 3/2 and Y intercept -1

Mashcka [7]

Answer:

$\large\boxed{y=\dfrac{3}{2}x-1}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

<em>m</em><em> - slope</em>

<em>b</em> - <em>y-intercept</em>

We have

$m=\dfrac{3}{2},\ b=-1$

Substitute:

$y=\dfrac{3}{2}x+(-1)=\dfrac{3}{2}x-1$

GEOMETRY!!! 15 PTSSSSS

ss7ja [257]

Answer:

23) option c

JL ≈ 9.3

25) option c

y ≈ 9.6

Step-by-step explanation:

Given in the question that,

cos(21°) = 9 / y

y = 9/cos(21°)

y = 9.64

y ≈ 9.6(nearest tenth)

Given in the question that the hypotenuse of right angle triangle = 12

To find,

height of the right angle triangle

angle k = 39°

so by using trigonometry identity

cos(39) = opp/hypo

cos(39) = JL / KL

JL = cos(39)(12)

JL = 9.32

JL ≈ 9.3
