Y = 2x - 3 . . . (1)
y = -2x + 5 . . . (2)
Equating (1) and (2),
2x - 3 = -2x + 5
2x + 2x = 5 + 3
4x = 8
x = 8/4 = 2
x = 2
y = 2(2) - 3 = 4 - 3 = 1
y = 1
Solution = (2, 1)
Answer:
Use the inflection points to set up intervals. Substitute a value into each interval to find where the curve is concave up or down.
The graph is concave up
Explanation:
Substitute:
3 for x
3 for y
1 for z
x(−y+z)
becomes:
3(−3+1)⇒
3 ⋅ −2 ⇒
−6
Answer:
Step-by-step explanation:
One of the properties of a rhombus is that the opposite angles are equal. As a rhombus leans over more and more, two of the angles become more obtuse and the other two become more acute.. There are also 4 pairs of parallel lines in a rhombus.
