Answer:
r = 1/2(s -t/x)
Step-by-step explanation:
Here, we simply want to make r the subject of the formula;
We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)
Answer:
f(4) - g(3) = 28
Step-by-step explanation:
f(x) = 8x + 10
f(4) = 8(4) + 10
f(4) = 32 + 10
f(4) = 42
g(x) = 6x - 4
g(3) = 6(3) - 4
g(3) = 18 - 4
g(3) = 14
f(4) - g(3)
= 42 - 14
= 28
Simple...
you have: 8x-6y=1
To find m (slope) re-write in y=mx+b form
8x-6y=1
8x-6y=1
-8x -8x
-6y=-8x+1
Now simply divide by -6--->>

m=
Thus, your answer.
8( 7x - 1) +4(x + 5) = 56x - 8 + 4x +20
56x - 8 + 4x + 20 = 60x + 12
Answer = 60x + 12
