What is one of the solutions to the following system of equations?

Amanda [17]

Answer:

(8,-1)

Step-by-step explanation:

Given : $x^{2} +y^{2} =65$

$x+y=7$

To Find: solution of given system of equations.

Solution:

Equation a : $x^{2} +y^{2} =65$

Equation b : $x+y=7$

Substitute the value of y from equation b in equation a

y from equation b : y = 7-x

Now substitute value of y in equation a

Thus equation a becomes:

$x^{2} +(7-x)^{2} =65$

$x^{2} +49+x^{2}-14x =65$

$2x^{2} -14x =65-49$

$x^{2} -7x -8=0$

$x^{2} -8x+x -8=0$

$x(x-8)+1(x-8)=0$

$(x+1)(x-8)=0$

⇒ x= -1 and x = 8

Now substitute values of x in equation b to obtains values of y

⇒ $x+y=7$

for x = -1

⇒ $-1+y=7$

⇒ $y=7+1$

⇒ $y=8$

Thus (x,y)=(-1,8)

For x =8

⇒ $8+y=7$

⇒ $y=7-8$

⇒ $y=-1$

Thus (x,y)=(8,-1)

Hence Option A is the correct solution .

grin007 [14]

Answer:

<h2>At least 21 cookie</h2>

Step-by-step explanation:

Firstly she needed to raise $150

and each cookie $5

let the number of cookie be x

let the expression for the fund raising be

150=5x

given that the mom gave her $45

then she need

150-45=5x

105=5x

x=105/5

x=21

Therefore she need to sell at least 21 cookie

HELP PLEASE WILL GIVE BRAINLIEST!!!

Cerrena [4.2K]

Answer:

$\fbox {Trapezoid ABCD and Trapezoid EFGH are congruent.}$

Step-by-step explanation:

<u>Finding corresponding side lengths</u> :

<u>Trapezium ABCD</u>

AB = √(-2)² + (-1)² = √5
BC = √(-1)² + (2)² = √5
CD = √(2)² + (2)² = 2√2
DA = √(-1)² + (5)² = √26

<u>Trapezium EFGH</u>

EF = √(2)² + (1)² = √5
FG = √(1)² + (2)² = √5
GH = √(-2)² + (2)² = 2√2
HE = √(1)² + (5)² = √26

As the corresponding side lengths are equal, we can conclude that the trapezoids are congruent.
