Answer:

  a) the distributive property

  b) Yes

Step-by-step explanation:

a) The distributive property of multiplication over addition tells you ...

  a(b+c) = ab +ac

James has a=3, b=8, c=7, so he can fill in the values to get ...

  3(8+7) = 3·8 +3·7

Taking this one step into the evaluation, James gets ...

  3(3+7) = 3·8 +3·7 = 24 +21 . . . . . . the result James reports

___

b) Our result agrees with James' result, so we agree with James.

Find the solutions to the system; y=x^2-3x-1 and y=8x-1
PSYCHO15rus [73]

{x}^{2}  - 3x - 1 = 8x - 1 \\  {x}^{2} - 11x = 0 \\ x(x - 11) \\ x = 0 \: or \: x = 11

When x = 0,
y = 8x - 1 \\ y = 0 - 1 \\ y =  - 1

When x = 11
y  = 8(11) - 1 \\ y = 87
x = 0, y = - 1
x = 11, y = 87

Answer is B.
