15 is the answer
5+7= 12
12-2= 10
10+5= 15
Hope this helps
Answer:
d
Step-by-step explanation:
using the distance formula
d = 
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )
d = 
= 
= 
= 
= 
≈ 12.369
21/35 = x/100
cross multiply
2100=35x
x = 60
<h2><u>
ABSOLUTE VALUE</u></h2>
The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.
<h3>Exercise</h3>
Replace the value of x:



The absolute value of a number is the numerical value of the number, without regard to its sign.
<h3><u>Answer.</u> 12</h3>
Answer:
-5/2x+3
Step-by-step explanation:
you reciprocate the slope since you are trying to find a line perpendicular.
From this m=2/5 to -5/2
then use the formula y-y1 =m(x-x1)
then you put in the points
y - - 2= -5/2(x- 2)
y+2= -5/2x +5
-2 -2
y= -5/2+ 3
