Answer:

y =  -  \frac{4}{5} x + 2 \frac{3}{5}

Step-by-step explanation:

To solve for y, we have to arrive at the equation of y= ____.

4x + 5y = 13

<em>-4x</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

5y = - 4x + 13

<em>Divide</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

<em>y =  -  \frac{4}{5} x +  \frac{13}{5}  \\ y =  -  \frac{4}{5} x + 2 \frac{3}{5}</em>

Answer:

Law of Sines

Step-by-step explanation:

Law of Sines: \frac{A}{sina} =\frac{B}{sinb} =\frac{C}{sinc}

Step 1: Solve for m∠B

\frac{25}{sin36} =\frac{27}{sinx}

25sinx = 27sin36°

sinx = 27sin36°/25

x = sin^{-1}(\frac{27sin36}{25} )

m∠B ≈ 39.4°

Step 3: Find m∠C

180 - (36 + 39.4)

180 - 75.4

m∠C = 104.6°

Solve the equation. Check your solutions when necessary.<br><br><br>2x² − 7x = 4
prisoha [69]

Answer:

x= -1/2 = -0.500

x=4

Step-by-step explanation:

2x^2-7x-4=0

2x^2-8x+1x-4=0

2x(x-4)+1(x-4)=0

(2x+1)(x-4)=0

2x+1=0...2x= -1.. x= -1/2         x-4=0 .. x=4

checking the solution

2(-1/2)^2-7(-1/2)=4.....  4=4

2(4)^2-7(4)=4....... 4=4
