Answer:

56 + 23 + (-5)

you want to expand the bracket first

23 + (-5)

23-5 = 18

56 + 18 = 74

a) 74

6 + 24 + (-2)

24 - 2= 22

6 + 22 = 28

b) 28

3 + 7 + (-42)

7 - 42 = -35

3 - 35 = -32

c)-32

( 8 + 1 ) + (-3)

+(-3) = -3

9 - 3 = 6

d)6

( 7 + 10 ) + ( 3 + 1 )

17 + 4 = 21

e)21

59 + 2+ (-6)

2+(-6) = 2-6 = -4

59-4

55

f)55

41 + ( -89)

41 - 89

= - 48

g)-48

( - 13) + 33

-13+33

= 20

h) 20

Whitepunk [10]

it gives you the formula, so all you have to do is plug in the coordinates

d =  \sqrt{ {( - 1 + 3)}^{2} +  {( - 1 - 1)}^{2}  }  \\ d =  \sqrt{ {(2)}^{2} +  {( - 2)}^{2}  } \\ d =  \sqrt{ 4 +  4  } \\ d =  \sqrt{8} \\ d = 2 \sqrt{3}  = 3.4641... \\  \\ d = 3.5

After a rotation, A(–3, 4) maps to A'(4, 3), B(4, –5) maps to B'(–5, –4), and C(1, 6) maps to C'(6, –1). Which rule describes th
Korvikt [17]

Answer:

Rotated at 90° clockwise about the origin. (RO 90)

Step-by-step explanation:

According to the statement A(–3, 4) maps to A'(4, 3), B(4, –5) maps to B'(–5, –4), and C(1, 6) maps to C'(6, –1). That is to say, that a point in the form P(x, y) maps to P(y, -x) after rotation.

In that sense, if a point P(x, y) maps to P(y, -x) then this happens when the shape denoted by those three points is rotated at 90° clockwise about the origin.

N is a positive integer.<br> Explain why n(n-1) must be an even number.
svetoff [14.1K]
If N is a positive integer, it must be either even or odd. If N is odd, then N-1 will be even. If N is even, then N-1 will be odd. Either way, when you multiply n and n-1, one of those expressions is going to be an even number, and any number multiplied by an even number is an even number. Hope this helps! :)

How much, in total, did Noel spend to cash her three most recent paychecks?
Stolb23 [73]

Based on the amount that Noel cashed in each of her most recent paychecks, the amount she spent in total is $10.99.

<h3>How much did Noel spend?</h3>

The bank directory shows that you are charged 1.99% of the amount being cashed as well as a check processing fee of $1.39.

The amount Noel spent is therefore:

= (1.99% x 100.53) + (1.99% x 119.38) + (1.99% x 122.52) + (1.39 x 3 checks)

= 2.00 + 2.38 + 2.44 + 4.17

= $10.99
