A = first battery type
b = second battery type

a + b = 6.5 V
a = ( 6.5 V ) - b

b - a = 2.5 V

b - (6.5 - b) = 2.5
2b - 6.5 = 2.5
2b = 9.0
b = 4.5 V
a = 6.5 - 4.5
a = 2.0 V

3² +4² = 5²,
AlekseyPX

Answer:

They are all true

Step-by-step explanation:

1. 3² +4² = 5²

3x3 + 4x4 = 5x5

  9   +  16  =  25

25 = 25

-----------------------

2. 6² + 8² = 10²

36 + 64 = 100

100 = 100

------------------

3. 9² + 12² = 15²

81 + 144 = 225

225 = 225

-------------------

4. 5² +12² =13²

25 + 144 = 169

169 =169

-------------------

Answer:

y = -3x + 6

Step-by-step explanation:

We can first find the y intercept by looking at y when x = 0

y intercept = 6

We can then find the slope by looking at the patterns on the tables.

As we can see, the top row's pattern is +4 every time

The bottom row's pattern is -12

Slope = rise/run

-12/4 = -3

Therefore, the equation for the chart is y = -3x + 6
