Answer:
Step-by-step explanation:
The equation for that is
![x^2+3x=70](https://tex.z-dn.net/?f=x%5E2%2B3x%3D70)
If we subtract over the 70, we have a quadratic that we can factor to solve for the values of x that will make that equation true.
![x^2+3x-70=0](https://tex.z-dn.net/?f=x%5E2%2B3x-70%3D0)
Now we need the factors of 70 that will either add or subtract to give us the linear term of 3. The factors of 70 that will work are 10 and 7. 10 times 7 is 70, and 10 - 7 = 3:
and now we will factor by grouping:
and factor out what's common:
![x(x+10)-7(x+10)=0](https://tex.z-dn.net/?f=x%28x%2B10%29-7%28x%2B10%29%3D0)
The factor (x + 10) is common, so we will now factor that out:
![(x+10)(x-7)=0](https://tex.z-dn.net/?f=%28x%2B10%29%28x-7%29%3D0)
By the Zero Product Property, either x + 10 = 0 or x - 7 = 0, so x = -10 or 7
Those are the 2 numbers that will work.
simplifies to
100 - 30 which does in fact equal 70. OR
which simplifies to
49 + 21 which also equals 70.
So you're done!
Obtaining thevslope you get 6/5. so
9=-24/5 +n
=
y=6/5x + 21/5
Answer:
Step-by-step explanation:
<h2>
Answer:</h2>
4x - 6 + 2x = 3(2x - 2)
4x - 6 + 2x = 6x - 6
[ both sides - 6 cancel each other ]
4x + 2x = 6x
6x = 6x
[ both sides 6x cancel each other ]
0 = 0.
First start by writing th equation y=mx+b then because we know the slope (m) is perpendicular to the other line we can find it. so it would be the negative reciprocal to -13 which is 1/13 then you can use the slope and the x and y point and sub them into the equation to find the b value
y=3 x=4 m=1/13
3=1/13*4+b then solve for b
3=4/13+b
3-4/13=b
2.69=b
the write out the equation
y=1/13x+2.69
