Answer:
A -60i - 14j
Step-by-step explanation:
u = -9i + 8j
v = 7i + 5j
2u = 2(-9i + 8j) = -18i + 16j
6v = 6(7i + 5j) = 42i + 30j
2u - 6v
(-18i + 16j) - (42i + 30j)
(-18i - 42i) + (16j-30j)
-60i - 14j
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
The correct answer is 12:16 P.M.
<h3>How to find when did Deb finish eating lunch ?</h3>
According to the problem,
- Deb started doing yard work at 9:52 A.M.
- After working for 1 hour and 48 minutes, she stopped to have lunch.
- It took her 36 minutes to eat lunch.
∴ Time at which Dev finishes her lunch =
9:52 A.M. + ( 1 hour and 48 minutes + 36 minutes )
= 11:40 A.M. + 36 minutes = 12 : 16 P.M.
∴ Deb finish eating lunch at 12:16 P.M.
