<u>Answer : </u>
The value of r in (4,r),(r,2) so that the slope of the line containing them is is 7
<u>Solution: </u>
Slope of the line which is passes through
→ (1)
From question given that two points are (4, r), (r, 2). Hence we get
By substituting the values in equation (1),
→ (2)
Also given that slope that is m = , so on substituting the value of m in equation (2),
On simplifying,
-5r+20=6-3r
5r-3r=20-6
2r = 14
r =7
Hence value of r is 7.
Answer
a= -6
Step-by-step explanation:
-2(a-3)=12
1.) -2(a)= -2a
2) -2(-3)= 6
3) -2a+6=12
-6 -6
4) -2a/-2 = 12/-2
a = -6

Answer: w^6/9
Step-by-step explanation:
first, i evaluated the powers.
3^-2 x 1 x 1/w^-6
then, i calculated those products.
3^-2/w^-6
then, i just expressed it with a positive exponent.
w^6/3^2
finally, i evaluated that.
w^6/9
