Answer:
![y = 1x - 4](https://tex.z-dn.net/?f=y%20%3D%201x%20-%204)
Step-by-step explanation:
You have to solve for the x intercept on the equation
![2x-5y=8\\2x-5(0)=8\\2x=8\\x=4\\(4,0)](https://tex.z-dn.net/?f=2x-5y%3D8%5C%5C2x-5%280%29%3D8%5C%5C2x%3D8%5C%5Cx%3D4%5C%5C%284%2C0%29)
That is the x intercept for that equation.
Then solve for the y intercept on the equation
![4x-3y=12\\4(0)-3y=12\\-3y=12\\y=-4\\(0,-4)](https://tex.z-dn.net/?f=4x-3y%3D12%5C%5C4%280%29-3y%3D12%5C%5C-3y%3D12%5C%5Cy%3D-4%5C%5C%280%2C-4%29)
That is the x intercept for that equation.
Use that to find slope for point slope form
![\frac{y_{2}-y_{1}}{x_{2}-_{1}} \\\\\frac{-4-0}{0-4} \\\\\frac{-4}{-4} \\\\1](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-_%7B1%7D%7D%20%5C%5C%5C%5C%5Cfrac%7B-4-0%7D%7B0-4%7D%20%5C%5C%5C%5C%5Cfrac%7B-4%7D%7B-4%7D%20%5C%5C%5C%5C1)
1 is the slope
and slope makes B the y intercept so the equation is
![y = 1x - 4](https://tex.z-dn.net/?f=y%20%3D%201x%20-%204)
Answer:
he sold 4 boxes of cookies and 3 chocolate bars
Step-by-step explanation:
5+5+5+5 = 20 3+3+3 = 9 so add 20+9 = 29
Step-by-step explanation:
to compare them, we should all bring to the same denominator.
the lcm (lowest common multiplier) is the that denominator.
let's use the approach of the prime factors :
3 : 3
5 : 5
32 : 2×2×2×2×2
24 : 2×2×2×3
the lcm is the combination of the longest "streaks" of the prime factors.
so,
2×2×2×2×2 × 3 × 5 = 32×15 = 480
2/-3 = -2/3 = -320/480 (as 3×160 = 480)
-4/5 = -4×96 / 5×96 = -384/480 (as 5×96 = 480)
21/-32 = -21/32 = -315/480 (as 32×15 = 480)
-15/24 = -15×20 / 24×20 = -300/480 (24×20 = 480)
as
-384/480 < -320/480 < -315/480 < -300/480
we can say
-4/5 < -2/3 < -21/32 < -15/24
5(2x-3)-(x+8)=13
10x-15-x-8=13
9x-23=13
9x=36
x=4
