Answer:

80

Step-by-step explanation:

x^3+x^2        

(4)^3+(4)^2       Replace the variable x with 4 in the expression.

64+(4)^2         Raise 4 to the power of 3.

64+16           Raise 4 to the power of 2.

80                  Add 64 and 16.

Answer:

y = -1/2x + 3.5

Step-by-step explanation:

The gradients of perpendicular lines multiply to make -1. The gradient of the line given is 2, so 2 multiplied by something gives us -1. 2 × -1/2 = -1. The gradient of the perpendicular line is -1/2

y = -1/2x + c

Now we can substitute x = 1 and y = 3 into the equation:

  • 3 = -1/2(1) + c
  • 3 = -1/2 + c
  • c = 3 + 1/2
  • c = 3 1/2 or 3.5 or 7/2

The equation of the line is y = -1/2x + 3.5

Hope this helps!
