Solution1: 9(x) + (y) = 17  

Solution 2: 9(x) + 9(y) = 19

Your graphic organizer ➡(y) - 9(x) = 17
9(y) + 9(x) = 19

(y) = 9(x) + 17(⬅Solution 1)

9(x) + 9(9)(x)+17 = 19 ;  90(x) = -134(⬅Solution 2)

(x) = -67÷45
= -1.48

  y = 18 ÷ 5
=3.6.

x-intercept ➡ -67/45

y-intercept: 18/5
⬆

y = 3.6; 18/5 (if that's what you're looking for)

<span>SAS You've been given that AC = BC. So that's the first side or S of the proof. Then you've been given â 3 = â 4, which is the angle. And finally, CM = CM, which is the second S. So you have AC=BC, and â 3 = â 4, and finally CM = CM. So SAS can be used to prove that triangle ACM is congruent to triangle BCM.</span>

GrogVix [38]

Answer:

(\frac{dy}{dt})^2=sin^2t

Step-by-step explanation:

y=cost

DE :(\frac{dy}{dt})^2=1-y^2

If y is a solution of given DE then it satisfied the DE.

Differentiate w.r.t t

\frac{dy}{dt}=-sint

Using the formula

\frac{d(cosx)}{dx}=-sinx

LHS:(\frac{dy}{dt})^2=(-sint)^2=sin^2t

RHS

1-y^2=1-cos^2t=sin^2t

By using the formula

sin^2t=1-cos^2t

LHS=RHs

Hence, y is a solution of given DE

(\frac{dy}{dt})^2=sin^2t
