solve systems of equation. equation number 1: 9 x squared + 4 y squared equals 144. equation 2: x squared plus y squared equals

grigory [225]

$9x^{2} + 4y^{2} =144$
$x^{2} + y^{2}=24$

$9x^{2} + 4y^{2} =144$
$4x^{2} + 4y^{2}=96$
by the difference
5 $x^{2}$ =48
so x= $\sqrt{\frac{48}{5}}$ or x=- $\sqrt{\frac{48}{5}}$
and $y^{2}$ =24- $\frac{48}{5}$
then y= $\sqrt{\frac{72}{5}}$ or - $\sqrt{\frac{48}{5}}$

Find y of this triangle.

kvasek [131]

Answer:

y =52

Step-by-step explanation:

We know that the angles 4x and 5x make a straight line

4x+5x = 180

9x = 180

Divide by 9

9x/9 = 180/9

x = 20

The three angles of a triangle make 180

y + 48 +4x = 180

y + 48+4(20) =180

y + 48 +80 = 180

Combine like terms

y +128 = 180

Subtract 128 from each side

y + 128-128 = 180-128

y =52
