Answer:
There is no x value, as there is no solution
Step-by-step explanation:
we have
2x+y=1
Isolate the variable y
y=-2x+1 -----> equation A
4x+2y=-1 ---> equation B
Solve the system of equations by substitution
Substitute the equation A in the equation B and solve for x
4x+2(-2x+1)=-1
4x-4x+2=-1
2=-1 ------> is not true
therefore
The system has no solution
Equation A and equation B are parallel lines with different y-intercepts
7 leaves per day for a whole week
there are seven days in a week
7 times 7 is 49
because she picked up seven leaves per day for a week straight

Answer:
s = 6, r = 8 or s = 4, r = 7
Step-by-step explanation:
2r - s = 10
2r = 10 + s
r = 5 + s/2 --(1)
rs - s^2 = 12 --(2)
sub (1) into (2):
(5 + s/2)s - s^2 = 12
5s + 0.5s^2 - s^2 = 12
-0.5s^2 + 5s - 12 = 0
s^2 - 10s + 24 = 0
(s - 6)(s - 4) = 0
therefore s = 6 or s = 4
when s = 6, r = 8 and when s = 4, r = 7
