Answer:
Step-by-step explanation:
1.
x - 5 = 0
x = 5
2.
x + 6 = 0
x = -6
3.
2x + 4 = 0
2x = -4
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-4}{2}[/tex]
x = -2
4.
3x + 4 = 0
3x = -4
[tex]\frac{3x}{3} = \frac{-4}{3}[/tex]
x = - [tex]\frac{4}{3}[/tex]
5.
- 4x + 1 = 0
- 4x = - 1
[tex]\frac{-4x}{-4} = \frac{-1}{-4}[/tex]
x = [tex]\frac{1}{4}[/tex]
6.
-3x - 2 = 0
-3x = 2
[tex]\frac{-3x}{-3} = \frac{2}{-3}[/tex]
x = [tex]- \frac{2}{3}[/tex]
7. 6x - 7 = 0
6x = 7
[tex]\frac{6x}{6} = \frac{7}{6}[/tex]
x = [tex]\frac{7}{6}[/tex]
8. 6x - 7x + 5 = 0
-x + 5 = 0
-x = -5
[tex]\frac{-x}{-} = \frac{-5}{-}[/tex]
x = 5
Answer:
Give the zero of each linear function
1. f (x) = x - 5
Substitute f(x) to zero
0=x-5
Move the variable to the left
-x=-5
Change the sign
x=5
2. F (x) = x + 6
Same explanation in the previous number
0=x+6
-x=6
x=6
3. g (x) = 2x + 4
Same explanation in the previous number 0=2x+4
-2x=4
Divide both sides by -2
x=-2
4. G (x) = 3x + 4
Same explanation in the previous number
0=3x+4
-3x=4
x= -4/3
5. h (x) = -4 x + 1
Same explanation in the previous number
0=-4x+1
4x=1
x=1/4
6. H (x) = -3x -2
Same explanation in the previous number
0=-3x-2
3x=-2
x= -2/3
7. y = 6x -7
Same explanation in the previous number
0=6x-7
-6x=-7
x= 7/6 or 1 1/6
8. y =6x -7 x + 5
Same explanation in the previous number
0=6x-7x+5
0=x+5
x=5
9. 2x + y = 30
Same explanation in the previous number
2x+0=30
2x=30
x=15
10. -4x + 3y = 8
-4x+3(0)=8
-4x+0=8
-4x=8
x=-2
