2c^5 + 44c^4 + 242c^3
Take out common factors.
= 2c^3(c^2 + 22c + 121)
( Refer for attachment for next step )
= 2c^3(c + 11)(c + 11)
= 2c^3(c + 11)^2
Use substitution
Plug in 5x for y
5x = 2x - 15
Subtract 2x
3x = -15
Divide by 3
x = -5, y = -25
Solution: (-5, -25)
Answer:
Sara read 17 more
Step-by-step explanation:
81-64=17
64+17=84
We have 3*4+2, or 14, by substituting in for x.
Answer:
Step-by-step explanation:
1)y=-6x-14 ---------(i)
-x-3y=-9 ---------- (ii)
Substitution method:
Substitute y value in equ (i)
-x -3*(-6x-14) = -9
-x - 3*-6x -3*(-14)= -9
-x + 18x + 42 = -9
17x = -9 -42
17x = -51
x = -51/17
x = -3
Substitute x value in equation (i)
y = -6*-3 -14
y =18-14
y = 4
