True
Step-by-step explanation:
A system of equations can be solved by Translating the system of equations into a matrix by following theses steps
- list all coefficients in a single matrix
- multiply the coefficient matrix with the variables matrix
- enter answers into a new matrix
write out the resulting answer in form of equations.
1 5
- + -
8 8
or
1/8 + 1.25/2
This is how it is done. Let me know if you have questions...
Answer:
Step-by-step explanation:
You read a graph from left to right, just like you would read words on a page in a book. At the left-most "side" of this graph, we are way up at positive infinity. As we move from left to right, the graph begins to drop in y values. A drop in y values indicates a decreasing graph. So it's decreasing, we have that part. As the graph grows up into y values that increase forever, it will also grow in the x direction to negative infinity. As the graph decreases in y values from left to right, the x values increase into positive infinity. So your choice is the second one: The function is decreasing on the interval (-∞, ∞).
Answer:
Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines.
