point I is on line segment HJ. GIVEN IJ = 3× + 3, HI = 3× - 1, and HJ = 3× + 8, determine the numerical length of HJ.
Vedmedyk [2.9K]

Given, IJ = 3x + 3, HI = 3x - 1, and HJ = 3x + 8.

Since I is a point on line segment HJ, we can write

HJ=HI+IJ\begin{gathered} 3x+8=(3x-1)+(3x+3) \\ 3x+8=6x+2 \\ 8-2=6x-3x \\ 6=3x \\ 2=x \end{gathered}

Put x=2 in HJ=3x+8.

\begin{gathered} HJ=3\times2+8 \\ HJ=6+8 \\ =14 \end{gathered}

Therefore, the numerical length of HJ is 14.

The relationship between fahrenheit and celsius scales is given by F=9/5C+32. Determine the value in celsius when F=-3?
IgorLugansk [536]
-3 = 9C/5 + 32

9C/5 = - 32 - 3

9C/5 = - 35

9C = - 175

C = -175/9

C = - 19.44
