The equation y = 2x + 1 is changed to y = 2x - 1. How does this change the graph of the line?

Y = 2x + 1
y = 2x - 1

so the 1st one has a y int of 1 and the second one has a y int of -1...so the original line will shift down 2 units

Answer:

D) The original line will shift down 2 units.

Step-by-step explanation:

The rate of changes [slopes] remain the same [2], so all you need to do is figure out how much far $\displaystyle [0, 1]$ is from $\displaystyle [0, -1],$ and that would be two units:

$\displaystyle -1 + 2 = 1$

Please, show me how to find the limit. lim θ sin θ θ→π Thank you!

Morgarella [4.7K]

Ignore the fact that it says limit because when sin (pi) is here it is not an Undefined Point, whatever value the calculator says is sin(pi) is the answer.

How to solve this equation 2(f+3)+4f=6+6f?

Tresset [83]

2f+6+4f=6+6f
6f+6-6=6-6+6f
6f=6f
This means f can equal any number which we call mathematically infinite solution or infinitely many solutions

Two thirds of a number is no more than -10

Aliun [14]

Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have

$\frac{2}{3}$ x≤-10

In order to cancel out the $\frac{2}{3}$ on the left and isolate x, we multiply both sides by $\frac{3}{2}$ (since $\frac{3}{2}$ · $\frac{2}{3}$ =1). Thus, we have

x≤-10· $\frac{3}{2}$ =-15

Therefore, x≤-15
