Answer:
option f
option a
option d
option c
option e
option b
Step-by-step explanation:
we have x^2 - 6x + 7 = 0
f) x^2 - 6x = -7
a) x^2 - 6x + 9 = -7+9
d) (x-3)^2=2
c)
e) x-3=+-
b) x=3+-
The x-coordinate in the solution of the system of equations y = -2/3x and 4x - 9y = -40 is -4
<h3><u>Solution:</u></h3>
<em><u>Given that system of equations are:</u></em>
------- eqn 1
------ eqn 2
We have to solve the above given system of equations and find the x - coordinate
<em><u>Substitute eqn 1 in eqn 2 and solve for "x"</u></em>
x = -4
Thus the x-coordinate in the solution of the system of equations is -4
