What I need to know is how to find x and y values by representing the answers in simplest radical form where necessary
Maru [420]

Answer:

x = 0.6623

y = 8

Image is attached for refernce of my solution

Step-by-step explanation:

In Δ DEF

By applying pythagoras theoram,

DE = \sqrt{EF^{2} - DF^{2}  }

     =\sqrt{17^{2} - 15^{2}  }  = \sqrt{289 - 225}  = \sqrt{64}  =8

∴ DE = 8

In Δ ABC

BC = y = 12 sin 30° = 6

AC = \sqrt{3} + DE + x = \sqrt{3} + 8 + x = 12 cos 30°

⇒ 9.73 + x = 10.39

<h3>⇒ x = 0.6623</h3>

if you subtract 17 from my number and multiply the difference by -6 the results is -138 what is Sarah's number
likoan [24]

Answer:

40

Step-by-step explanation:

let the unknown be y (x is used as times(multiplication) )

(y-17)x-6=-138

add /-6 to both sides

y-17x-6/-6=-138/-6

y-17=23

make y independent/add 17 to both sides

y-17+17=23+17

y=40

or in an easier way

-138/-6 =23

23+17=40

Which equation has a slope of –3/2 and a y-intercept of 5?
Natasha_Volkova [10]
I’m not sure what you’re options are but an equation in Y=mx+b form for this would be y= -3/2x + 5

M is always the slope
B is always the y intercept

What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375
Anna [14]
C. 427

The median is the middle number of all the data

Since there is an even number of data points the median is in between the middle two data points (434 and 420)

To find this: 434-420=14
14/2=7
434-7=427
420+7=427
