The formula of the distance between two points:

We have the points (-1, -10) and (-12, -3). Substitute:


Answer: d ≈ 13.0
Answer:

Step-by-step explanation:
The two ringtones will cost her a total of
and is a fixed amount. The relationship between the cost and number of songs only is
and therefore the answer is
. You can also directly find the answer by finding the y-intercept (in this case
), as no other answer choices include the term
, so A must be the correct answer.
F(-5)=6(5*5)+4(-5)-11
f(-5)=6(25)+-20+-11
f(-5)=150+20-11
f(-5)=130-11=119
Answer:

Step-by-step explanation:
- Our equation is
- Now there are 2 ways you can do this, I'll show you the shortcut
- If you have an equation like this, just take the value in parenthesis and equate it to zero
is the x of the vertex- Put this back into the equation
this is the y
Let’s say (5, 3) is Point A, (5, -4) is Point B, and (8, 3) is Point C. If reflected into the y axis, you would simply just make the x signs the opposite of what they already are. Therefore Point A being (-5, 3), Point B being (-5, 4), and Point C being (-8, 3).
