Evan said that the difference between two negative numbers must be negative. Was he right?
geniusboy [140]
No
lets say a and b are positive numbers
that means -a and -b are negative
if you make the difference between these to it'd be
-a-(-b) which means -a+b, and if b>a then the difference is positive

Determine whether each table represents a linear, quadratic, exponential function.
Nesterboy [21]

Answer:

A: Exponential

B: Quadratic

C: Linear

Step-by-step explanation:

Let analyse each table

  • Table A

X            Y              ΔY/ΔX

1             5               xxxxxx              

2            11            11 - 5 = 6            

3           29             29 - 11 = 18          

4           83             83 - 29 = 54

.....................

We can see that, [ ΔY/ΔX ]   increases at the fastest rate out of all functions, so it must be exponential function

  • Table B

X            Y                 ΔY/ΔX            Δ^2Y/ΔX^2          

0             5                 xxxxxx              xxx              

1              7                 7 - 5 = 2            xxx            

2             13               13 - 7 = 6           6-2 = 4        

3             23              23 - 13 = 10       10-6 = 4

..............................

It is a quadratic because Δ^2Y/ΔX^2 = 4 and are constant for all values

  • Table C

X            Y                 ΔY/ΔX                      

3             20               xxxxxx                  

6             18                 2 / 3

9             16                 2 / 3                    

15            12                 2 / 3      

..............

It is a linear because ΔY/ΔX = 2/3 are constant for all values

A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Which statement about the quadrilateral is true?
Aleksandr-060686 [28]

Answer: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Find:

You can see that vectors and This means that opposite sides are parallel and option B is false.

Find the lengths of all sides:

As you can see the lengths of opposite sides are equal, but all lengths are not equal. Therefore, the last option D is false.

Now check whether angles A and B are perpendicular:

The dot products are not equal to zero, then angles A and B are nor right. This means that option C is false and option A is correct (ABCD is a parallelogram with non-perpendicular adjacent sides

AKA your correct awnser choice is A :)✨
