The answer should be 6 I.e 6^1 as with indices rules you need to subtract the powers (-3-(-4)) which equals 1

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!

At the market, 7 apples cost $4.55. How much do 9 apples cost?
Dvinal [7]
7 apples = 4.55
To find the single cost of an apple, divide 4.55 by 7
4.55/7 = 0.65 per apple
Let's check to see if this is right.
0.65 x 7 = 4.55 = correct
0.65 x 9 = $5.85 for 9 apples
