Answer:

Part A : a) -8  b) 12

Part B : a) 0.5  b) -1

Step-by-step explanation:

For Part A:

Let the algebraic expression be [tex]p_{1} = 4x[/tex]

so,

put [tex]x = -2\\[/tex] we get

[tex]p_{1} = 4\times-2[/tex]

[tex]p_{1} = -8[/tex]

put [tex]x = 3\\[/tex] we get

[tex]p_{1} = 4\times 3[/tex]

[tex]p_{1} = 12[/tex]

For Part B:

Let the algebraic expression be [tex]p_{2} = 3x +2[/tex]

so,

put [tex]x = -0.5\\[/tex] we get

[tex]p_{2} = 3\times-0.5 + 2[/tex]

[tex]p_{2} = -1.5 + 2[/tex]

[tex]p_{2} = 0.5[/tex]

put [tex]x = -1\\[/tex] we get

[tex]p_{2} = 3\times-1 +2[/tex]

[tex]p_{2} = -3 +2[/tex]

[tex]p_{2} = -1[/tex]
