Find the values of x and y

Elanso [62]

3x-11 =2x+11
x=22

y = 180 - [{3(22)-11} +{2(22)+11}]
y= 180 - 110
y = 70

Therefore: x=22 and y = 70

What are the solutions to the quadratic equation (5y+6)2=24

yulyashka [42]

The value of y is, $y=\frac{2\sqrt{6}-6}{5},\:y=\frac{-2\sqrt{6}-6}{5}$

We have given that,

$\left(5y+6\right)^2=24$

We have to determine the value of y,

<h3>What is the formula for the quadratic equation?</h3>

$\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

Therefore,we get

$5y+6=\sqrt{24}$

$5y+6=2\sqrt{6}$

$\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}$

$5y+6-6=2\sqrt{6}-6$

$5y=2\sqrt{6}-6$

$\frac{5y}{5}=\frac{2\sqrt{6}}{5}-\frac{6}{5}$

$y=\frac{2\sqrt{6}-6}{5}$

$y=\frac{2\sqrt{6}-6}{5},\:y=\frac{-2\sqrt{6}-6}{5}$

Therefore the value of y is,

$y=\frac{2\sqrt{6}-6}{5},\:y=\frac{-2\sqrt{6}-6}{5}$

If r is an integer greater than 1, what is the value of (−1)r +1 if:

Goryan [66]

Answer:

1. 0

Step-by-step explanation:

I don't know the even number one. (−1)^r when r is an odd integer greater than 1 always will equal -1 then -1 + 1 = zero
