Answer:
The product of a non-zero rational number and an irrational number is irrational.
Answer:
Step-by-step explanation:
Depends on what you mean by multiplying by - 1. I assume you are not going to multiply the y or f(x) term by - 1.
If that is so, take an example. Suppose you have a graph that is y=x^2
That's a parabola that opens upwards and it has a line going through its focus which is a point on the +y axis.
When you multiply the right hand side by - 1, the graph you get will be y = - x^2.
That opens downward and the focus is on the - y axis.
That means that the effect of the graph is that it flips over the x axis, which I think is the third answer.
Answer:
x > 1
Step-by-step explanation:
5 - 2x < 7
-5 - 5
-2x < 2
/-2 /-2
(dividing by negative switches the sign)
x >- 1
