Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
Answer:
15/31
Step-by-step explanation:
substitute -9 were there's x in the function
f(-9)=2(-9)+3/4(-9)+5
=-18+3/-36+5
=-15/-31
the negatives cancel giving you
15/31
Answer:
1. (4, 3) and (-3, 4) has Slope = -1/7
2.(-2, 0) and (8, -4) has Slope = -2/5
Step-by-step explanation:
If two such points (a,b) and (c,d) are given, then the slope S is given as:
Now here, the given set of points are:
1. (4, 3) and (-3, 4)
Here, the slope S = 
⇒ S = -1/7
1. (-2, 0) and (8, -4)
Here, the slope S = 
⇒ S = -2/5
