Solve using the method of elimination and determine if the system has 1 solution, no solutions, or infinite solutions
xeze [42]

Answer:

(3,1) --> One solution

Step-by-step explanation:

Start by multiplying the first equation by 4:

-7x(4)+2y(4)=-19(4)

     -28x+8y=-76

In this scenario, we can eliminate 8y by subtracting the two equations:

-34x=-102

Divide both sides by -34

x=3

Plug 3 back in for x to solve for y

-7(3)+2y=-19

-21+2y=-19

Add 21 to both sides

2y=2

Divide both sides by 2

y=1

(x,y)=(3,1)

PLEASE HELP ASAP!!
Airida [17]

Answer:

C

Step-by-step explanation:

Hey There so the first step of this problem is to find the formula for circumference

C=2\pi r

given some of the values we can form an equation to solve for the radius (r)

31.4=3.14(2)r\\3.14(2)=6.28\\31.4=6.28r\\\frac{31.4}{6.28} =5

so we can conclude that the radius is equal to 5
