Answer:
Therefore,
Middle term = 8
Sequence,
a-d, a, a+d = 8-6, 8, 8+6
= 2,8,14
Step-by-step explanation:
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
Answer:
x(1,2) = -5 ± √61) / (-2)
Step-by-step explanation:
The ABC formula of quadratic equation states
x(1,2) = (-b ± √b^2 - 4ac) / 2a
-x^2 + 5x + 9 = 0
a = -1
b = 5
c = 9
Thus x(1,2) = (-b ± √b^2 - 4ac) / 2a
= (-5 ± √(-5)^2 - 4*(-1)*9) / 2*(-1)
= (-5 ± √25+36) / (-2)
= (-5 ± √61) / (-2)
Required equation is y - y1 = m(x - x1); where m is the slope and (x1, y1) = (1, 3)
y - 3 = 2(x - 1)
