Answer:
No solution
Step-by-step explanation:
from the second equation x = -8 + 2y
By substituting in the first equation 4(-8 + 2y) -8y = -16
-32 +8y -8y = -16
-32 = -16
the left hand side not equal the write and side
So there is no solution for the system of equations
means the two lines are parallel
Answer:
what?
Step-by-step explanation:
..................................................
Answer:
Equilateral triangle (Green)
60° rhombus (2 triangles) (Blue) that can be matched with two of the green triangles
30° Narrow rhombus (Beige) with the same side-length as the green triangle
Trapezoid (half hexagon or 3 triangles) (Red) that can be matched with three of the green triangles
Regular Hexagon (6 triangles) (Yellow) that can be matched with six of the green triangles
Square (Orange) with the same side-length as the green triangle
All the angles are multiples of 30° (1/12 of a circle): 30° (1×), 60° (2×), 90° (3×), 120° (4×), and 150° (5×).
Answer:
The correct answer is d. (40, 60)
Step-by-step explanation:
To start using the linear combination method, you need a variable that will cancel out. To get this, we will multiply the second equation by -20 and then add together.
x + y = 100
-1.4x - y = -116
-----------------
-0.4x = -16
x = 40
Now that we have the value of x, we plug into one of the original equations to find y.
x + y = 100
40 + y = 100
y = 60
