zaharov [31]

Answer:

  Yes, after 10 key presses, both will arrive at the number 30.

Step-by-step explanation:

The difference between the numbers on the calculators is reduced by 10 with each key press. After 10 key presses, the initial difference of 100 will be zero. After 10 key presses of (-7), the calculator starting at 100 will be ...

  100 +10(-7) = 30

After 10 key presses of (+3), the calculator starting at 0 will be ...

  0 +10(+3) = 30

Both calculators will show 30 after 10 key presses.

part a: 5

part b: no, ABC is not an equilateral triangle

Step-by-step explanation:

part a: if you do the distance formula for points A and B, you get 5

part b: using the distance formula again, points A to B and points A to C are both 5, but points B to C is 6, therefore it's not equilateral because all the sides have to be the same length

Can someone help me? I'm trying to find the slope form of 4x + 2y = 4.
Neporo4naja [7]
Here, Equation: 4x + 2y = 4
Divide the equation by 2, 
2x + y = 2
y = -2x + 2

Now, compare the equation with y = mx + c
Here, slope (m) = -2

In short, Your Answer would be -2

Hope this helps!
