B would equal logx (-2x^5/a)-2
A would equal -2x^3-b (The b is up there with the 3 as well. Like ^3-b)
Answer:
Jesicaa=$59
Ashley=$71
Devyn=$98
Step-by-step explanation:
Let Jessica's earning be x:
![Jessica=x\\\\Ashley=x+12\\\\Devyn=2x-20](https://tex.z-dn.net/?f=Jessica%3Dx%5C%5C%5C%5CAshley%3Dx%2B12%5C%5C%5C%5CDevyn%3D2x-20)
-Given that the total earnings for the three was$228. earnings per person is calculated as:
#Equate their earnings to the 228 to solve for x:
![x+(x+12)+(2x-20)=228\\\\4x-8=228\\\\4x=236\\\\x=59](https://tex.z-dn.net/?f=x%2B%28x%2B12%29%2B%282x-20%29%3D228%5C%5C%5C%5C4x-8%3D228%5C%5C%5C%5C4x%3D236%5C%5C%5C%5Cx%3D59)
#Substitute for x in each earning equation to determine individual earnings:
![Jessica=x=59\\\\Ashley=x+12=59+12=71\\\\Devyn=2x-20=59\times 2-20=98](https://tex.z-dn.net/?f=Jessica%3Dx%3D59%5C%5C%5C%5CAshley%3Dx%2B12%3D59%2B12%3D71%5C%5C%5C%5CDevyn%3D2x-20%3D59%5Ctimes%202-20%3D98)
Like terms have the same variables and exponents. Constants are also like terms.
The given expression is
Зу + 3y + 5+ 7x^3 - у - 6 - 7x^3
By combining like terms, it becomes
7x^3 - 7x^3 + 3y + 3y - y + 5 - 6
= 5y - 1
Answer:
6 * 10 * 6
Step-by-step explanation:
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2
hope it helps
