It is: 5(z+5) = 5z+25
Z2 - 5Z + 4 = 0 (Z- 1)(Z - 4) so, Z = 1 ---------- and Z = 4 -----------
9z-5z = 30+z 3z = 30 z = 10
The following steps lead you to the correct answer: 9z = 5z + 16 9z - 5z = 16 4z = 16 z = 4, thus the correct answer is z = 4
3/5z + 45
It is: 5(z+5) = 5z+25
Z2 - 5Z + 4 = 0 (Z- 1)(Z - 4) so, Z = 1 ---------- and Z = 4 -----------
9z-5z = 30+z 3z = 30 z = 10
The following steps lead you to the correct answer: 9z = 5z + 16 9z - 5z = 16 4z = 16 z = 4, thus the correct answer is z = 4
Add like terms to like: (2z - 20) + (3z + 5) = (2z + 3z) + (-20 + 5) = 5z - 15 2z is shorthand for z+z, 3z is shorthand for z+z+z, so: 2z + 3z = (z+z) + (z+z+z) = z+z+z+z+z = 5z Or, to put it another way, just add the coefficients: 2z + 3z = (2+3)z = 5z.
-4x + 6y - 5z = 60At the x-intercept, 'y' and 'z' are zero:-4x = 60 ===> x = -15At the y-intercept, 'x' and 'z' are zero:6y = 60 ===> y = 10At the z-intercept, 'x' and 'y' are zero:-5z = 60 ===> z = -12
The meaning is 5Z is five z is the z*68-35/57/=980@is the meaning.
5z2-33z-14 = 0 (5z + 2)(z - 7) = 0 {factored into two binomials} 5z + 2 = 0 or z - 7 = 0 {set each factor equal to 0} 5z = -2 or z = 7 {subtracted 2 and added 7, respectively} z = -2/5 or z = 7 {divided left equation by 5}
z = 20 (6x20) + (5x20) = 20
(5z - 3)(z - 3)
