Mathematics
1 answer:
katen-ka-za [31]3 years ago

Answer:

f = - \frac{19}{7}

Step-by-step explanation:

Given f varies directly with m then the equation relating them is

f = km ← k is the constant of variation

To find k use the condition f = - 19 when m = 14

- 19 = 14k ( divide both sides by 14 )

- \frac{19}{14} = k

f = - \frac{19}{14} m ← equation of variation

When m = 2 , then

f = - \frac{19}{14} × 2 = - \frac{19}{7}

GrogVix [38]
Einstein went on to present his findings mathematically: energy (E) equals mass (m) times the speed of light (c) squared (2), or E=mc2. The secret the equation revealed—that mass and energy are different forms of the same thing—had eluded scientists for centuries.

satela [25.4K]

Answer:

\left \{ {{y=-1} \atop {x=-4}} \right.

Step-by-step explanation:

\left \{ {{y=\frac{3}{4} x+2} \atop {5x+4y=-24}} \right.  \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+4*(\frac{3}{4}x+2)=-24 }} \right. \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+3x+8=-24}} \right.  \left \{ {{y=\frac{3}{4}x+2 } \atop {8x=-32}} \right. \\\left \{ {{y=\frac{3}{4}x+2 } \atop {x=-4}} \right.  \left \{ {{y=\frac{3}{4}*(-4)+2 } \atop {x=-4}} \right.  \left \{ {{y=-3+2} \atop {x=-4}} \right. =>\left \{ {{y=-1} \atop {x=-4}} \right.
