Tan 25.5 = h/x

Tan 20.5 = h / x+1

x tan 25.5 = (x+1) tan 20.5

x 0.476975532 = (x+1) 0.373884679

0.476975532x = 0.373884679x + 0.373884679

Deduct both sides by .373884679

0.103090853x = 0.373884679

x = 3.6267 is the first person.

Add one to get for the second person

X = 4.6267

3x+4y=5 what is this in slope intercept form
tia_tia [17]
Slope intercept form is to leave y by itself. ok this is the initial question 3x+4y=5 and we want y by itself. first subtract 3x by both sides. you now have 4y=5-3x, then divide 4 by both sides. y=5-3x/4, this is slope intercept form, if you still need help download the app socratic and photomath.

Which table represents a linear function?​
Andrew [12]

Answer:

The first table is the only table representing a linear function.

Step-by-step explanation:

<em>" You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear."</em>
