Im pretty sure it would be 4
Answer: y=-5x-16
Step-by-step explanation:
Since we are given the slope and the point, we can plug in the point to solve for y-intercept.
4=-5(-4)+b [multiply]
4=20+b [subtract both sides by 20]
b=-16
Now, we know the equation is y=-5x-16.
Answer:
D.
Step-by-step explanation:
I am assuming they are not allowing graphing calculators for this, which is kind of wacky, if you ask me.
Anyway, the greater or equal to can technically be used interchangeably, so it looks like this:
y > 2x --> y = 2x
And so, with that equation, the sign just tells you what section of the graph is included. In this case, everything above the line.
Answer:
2870
Step-by-step explanation: mind
each box weighed 10 more pounds
and he lifted 12 boxes
so if you multiply 12 x the weight and then 12 times 10 more pounds each you would have 12c +12*10
which uses the equation 12(c+10)
