Answer:
1 Expandir.
-28=-21x-28+21x
−28=−21x−28+21x
2 Simplifica -21x-28+21x−21x−28+21x a -28−28.
-28=-28
−28=−28
3 Ya que ambos lados son iguales, hay infinitas soluciones.

Answer:
Step-by-step explanation:
In y = mx + b form, the slope can be found in the m position
y = 7/6x + 2/3......slope(m) = 7/6 or 1.167
y = 7/5x + 7/5....slope(m) = 7/5 or 1.4
y = 6/5x + 11/5...slope(m) = 6/5 or 1.2
y = 5/4x + 15/4.....slope(m) = 5/4 or 1.25
so the greatest rate of change would be B. y = 7/5x + 7/5 with a slope of 7/5
Answer:
22 is the number
Step-by-step explanation:
When ratio
88:22
Is divided with 11 it gives 8:2
Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.
