x=-1/2+y/2
Step-by-step explanation:
Answer:
yoir question isn't clear. try uploading it again. make sure it is clear.
Answer:
The answer is no solutions.
Step-by-step explanation:
use systems of equations!
first, rewrite both equations so that the sum or difference includes the same variable.
notice how i made sure the coefficients that have x and y respectively line up.
with this, i can cancel out the x variables by making 2, and -4 as -8 (8+-8=0).
rewrite the equation.
distribute.
now we can successfully cancel out the x variable!
uh oh! it seems we can also cancel out the y variables..
18 is not equal to 0 and neither is -16. because of this, we can conclude there is no solution for this system of equations.
hope this helps!!

Answer:
t is between 0 seconds and 4.878
Step-by-step explanation:
Given:
Inequality:
Required
Determine the value(s) of t
To answer this question, we simply solve the inequality
Subtract 10 from both sides
Multiply through by -1
Solve the value of t using quadratic formula
Where
<em>a = 4.9; b = -22 and c = -9.25</em>
So:
Split the expression
or
or
or
Since t cannot be negative; Then
<em>Hence; t is between 0 seconds and 4.878</em>
