5x 2y = 7 y = x 1 What is the solution set of the given system? {(5/7, 12/7)} {(12/7, 5/7)} {(9/7, 16/7)} {(16/7, 9/7)}.

OLEGan [10]

The correct option is A, which is {(5/7, 12/7)}.

<h2>Given to us,</h2>

equation 1, 5x + 2y = 7,

equation 2, y = x+1

To solve the question, as given in equation 2 the value of y which is equal to x+1, Substitute the value of y in equation 1,

$5x + 2y = 7$

<h3>substituting,</h3>

$5x + 2(x+1) = 7\\5x+2x+2=7\\7x+2=7\\7x=7-2\\7x=5\\\\x= \dfrac{5}{7}$

Now, we have the value of x, substitute the value in equation 2, to get y,

$y=x+1\\y=(\frac{5}{7})+1\\$

Taking LCM,

$y=\frac{5+(1\times 7)}{7} \\y= \dfrac{12}{7}$

Hence, the correct option is A, which is {(5/7, 12/7)}.

<span>v = 4/3*pi*r^3

derivating both sides with respect to t
dv/dt = 4*pi*r^2*dr/dt

when d = 1.7, r = 0.85, and dv/dt = 2:
2 = 4*pi*(0.85)^2*dr/dt

thus
dr/dt = 1/(2pi*(0.85)^2)
=1/(2*3.14*0.85^2)
