Where is the shape?????????????????
Answer:
Option D.
Step-by-step explanation:
The given system of equations is
...(1)
...(2)
On simplifying the second equation, we get
On dividing by -1, we get
...(3)
It is clear that equation (1) and (3) are same equations. It means equation (1) and (2) represent the equivalent equation.
So, the given system of equations has infinitely many solutions.
Therefore, the correct option is D.
y = - 4x +3 when slope is -4
NOTE: Parallel lines have same slope.
For the line passing through point (-5, -6) the slope (m) = -4
Equation of that line:
(y - y1) = m (x -x1)
(y --6) = -4(x --5)
(y + 6) = -4(x + 5)
y + 6 = -4x -20
y = -4x -20 -6
y = -4x - 26
Let
x = # of <span>$5 dollar bills
y = </span># of <span>$10 dollar bills
x + y = 12 so x = 12 - y
5x + 10y = 95
substitute </span>x = 12 - y into 5x + 10y = 95
5x + 10y = 95
5(12 - y) + 10y = 95
60 - 5y + 10y = 95
5y = 35
y = 7
x = 12 - 7 = 5
answer
# of <span>$5 dollar bills = 5
</span># of $10 dollar bills = 7
x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
