Linear is simple
Linear doesn't pass by 0, it starts at a certain point. |

Nvm that's an easy one
3/4 x > 16
x = 16 divided by 3/4

"1 + 3/4 x > 17"
Easy, multiply x by 3/4 (aka multiply by three then divide by 4) and add one. From there you only shade graph if that number is greater than (not at least) 17.
Anyway, what don't you understand about linear equations? |

1 + 0.75x > 17
subtract 1, you are trying to keep X alone
0.75x > 16
Divide each side by 0.75, because you need the X alone
x > ( 16 / .75)

3/5 f - 1/2 < 2 + f
What I'd do first is subtract 3/5 F from both sides, making it
-1/2 < 2+ 2/5f
subtract 2
-2.5 < 2/5F
multiply each side by 5/2
-6.25 < F

3/5 f - 1/2 < 2 + f -f -2/5f - 1/2 < 2 +1/2 -2/5f < 5/2 *5 -2f < 25/2 /-2 f > -25/4 (note: the sign changed because you divided/multiplied by a negative) |

3/5 f - 1/2 < 2 + f move the variables and numbers to one side
3/5f - f < 2 + 1/2
-0.4f < 2.5 divide by -0.4 and flip the inequality sign
f > -6.25 |

3/5 f - 1/2 < 2 + f gonna use decimals because its easier on a computer
0.6f - 0.5 < 2 + f
0.6f < 2.5 + f (You start by adding 0.5, the number, to isolate the variable.)
-0.4f < 2.5 (Subtract the f to consolidate all of the variables into one.)
f > -6.25 (Divide by -0.4 on both sides to isolate the variable, f, as just a variable, as in, without an integer with it. You turn the < into > because you're dividing by a negative integer.)

is the same as
f > -6.25 ( which is how urs is formatted )
u also over complicated it so um
i win u loose |

I'm in secondary I honors because I didn't want to take tests over the summer and I've already finished the whole year's worth of material.
I'm pretty sure I did this in 8th grade anyway. |
