First you need to find the r, if C=2pieR, than 2.4=2pieR now you divide 2.4 by 2 so you got 1.2=pieR now you divide 1.2 by pie and obtained aproximately 0.38 miles, that is your R, now you do pie multiply by 0.38 exposant 2 and there you go, your answer is aproximately 0.45 miles2 :)

A system of equations is graphed on a coordinate plane.

zavuch27 [327]

Answer:

Option C is correct.

(1, 4)

Step-by-step explanation:

A system of equation is given :

2x + 3y =12 .....[1]

4x + 2y =10 .....[2]

Multiply equation [1] by 2 both sides we get;

$2(2x+3y) = 2(12)$

Using distributive property i,e $a \cdot(b+c) = a\cdot b+ a\cdot c$

4x + 6y = 24 .....[3]

Subtract equation [2] from [3] to eliminate x we get;

4x + 6y - 4x - 2y= 24 - 10

Combine like terms;

4y = 14

Divide both sides by 4 we get;

y = 3.5

Substitute the value of y in equation [1] we have;

2x + 3(3.5) =12

2x + 10.5 = 12

2x = 12 -10.5

2x = 1.5

Divide both sides by 2 we get;

x = 0.75

Solution = (0.75 , 3.5)

Best estimate solution = (1, 4)

Therefore, the best estimate solution of the given system of equation is, (1, 4)
