Answer:
3/5
Step-by-step explanation:
1/5 + 1/4 = 4/20 + 5/20 = 9/20 divided by 3/4
9/20 x 4/3 = 36/60 = 3/5. (Multiply by the reciprocal)
Answer:
102.2
Step-by-step explanation:
From these -Tx+y=S. If -T=Q/R, then y=-Qx/R+S, so Ry=-Qx+RS, Qx+Ry=RS=S.
If R is not equal to 1, or S is non-zero, the equations are inconsistent, so there would be no solutions.
If R=1 there are an infinite number of solutions given by Qx+y=S, or y=S-Qx or y=S+Tx.
If S=0, Qx+Ry=0 or y=-Qx/R or y=Tx.

Answer:
slope = - 
Step-by-step explanation:
the slope of the secant line in the closed interval [a, b ] is
slope = 
here [a, b ] = [1, 4 ]
f(b) = f(4) = - 
+ 5 = - 16 + 5 = - 11
f(a) = f(1) = - 
+ 5 = - 2 + 5 = 3
slope = 
= 
= -
