Please help me ASAP!!

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Step-by-step explanation:

7z²+8z+3-3z²=0

4z²+8z+3=0

(2z+3)(2z+1)=0

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Step-by-step explanation:

7z^2 + 8z + 3 = 3z^2

4z^2 + 8z + 3 = 0

(2z + 3)(2z + 1) = 0

2z + 3 = 0

z = -3/2

2z + 1 = 0

z = -1/2

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
