Answer:
k=42.5573 and x=0.015699
Step-by-step explanation:
Step: Solve k=35.5x+42for k:
k=35.5x+42
Step: Substitute 35.5x+42 for k in k=991x+27:
k=991x+27
35.5x+42=991x+27
35.5x+42+−991x=991x+27+−991x(Add -991x to both sides)
−955.5x+42=27
−955.5x+42+−42=27+−42(Add -42 to both sides)
−955.5x=−15
−955.5x
−955.5
=
−15
−955.5
(Divide both sides by -955.5)
x=0.015699
Step: Substitute0.015699 for x in k=35.5x+42:
k=35.5x+42
k=(35.5)(0.015699)+42
k=42.5573(Simplify both sides of the equation)
Hope this helps!

Step-by-step explanation:
the rate of change is officially
(f(x2) - f(x1)) / (x2 - x1)
but for a line function (as we have here) this is totally easy : it is the slope of the line.
and that means it is the factor of x.
in our case this is -3/2.
because the slope of a line is the ratio "y coordinate change / x coordinate change". and that is exactly corresponding to the general rate of change definition above.
Answer:
RSU = 75.2°
Step-by-step explanation:
this is because:
⇒ RSU = RST + TSU
⇒ RSU = 48 + 27.2
⇒ RSU = 75.2°
Hence proved
