Answer:
![3x^2+126x](https://tex.z-dn.net/?f=3x%5E2%2B126x)
Step-by-step explanation:
Solve For X.
3x(x+42)
Ans:
3x(x+42)
Use the distributive property to multiply 3x by x+42.
![3x^2+126x](https://tex.z-dn.net/?f=3x%5E2%2B126x)
So the first thing you would want to do is rewrite the equation like so.
−x+4y=−3;−5x−4y=−15
once you done that you'll have to think about what variable are you trying to get be itself which in this case it'll be x. So now you'll be solving this equation.
−x+4y=−3
next you'll add -4y to both sides
Once you done so you should have this written down
-x over -1 = 4y- 3 over -1
divide -1 to both sides and you should end up with x= 4y+3
Now you have to substitute 4y+3 for x in -5x-4y=-15
So it should look like this now
−5(4y+3)−4y=−15
The next step is to simplify both sides with the following equation
−24y−15=−15
After simplifying add 15 to both sides, It then should look like this
−24y=0
Divide -24 to both sides and your answer should be this
y=0
hope this helps :)
Answer: m=-2/3
Y=-2
Equation=-2/3x-2
Step-by-step explanation:
M is the slope
Y is where it touches that y axis
Put it together
Answer:
.25
Step-by-step explanation:
Rate of change is the same as slope.
Slope is rise/run.
The rise between each y coordinate is consistently .5
The run between each x coordinate is consistently 2
Rise/Run = .5/2
Rate of change = .25
