Answer:

y = -13

Step-by-step explanation:

y = 3x - 1             equation(i)

2x - y = 5            equation(ii)

now substitute the value of y in equation(ii)

2x - y = 5

2x - (3x -1) = 5

2x - 3x + 1 = 5

-x = 5 -1

-x = 4

x = -4

again substitute the value of x in equation (i)

y = 3x - 1

y = 3*-4 - 1

y = -12 - 1

y = -13

Donald has a bunch of nickels and dimes in his piggy bank. There are 100 coins in the bank that make a total of $6.60 in change.
brilliants [131]

Answer:

78 nickels and 22 dimes

Step-by-step explanation:

Nickels = n, Dimes = d

<u>Number of coins = 100</u>

  • n + d = 100

<u>Total sum in the piggy bank = $6.60 </u>

  • 5n + 10d = 660

<u>Consider the first equation in the second:</u>

  • 5(100 -d) + 10d = 660
  • 500 - 5d + 10d = 660
  • 5d = 110
  • d = 110/5
  • d = 22
  • n = 100 - 22
  • n = 78

<u>Answer:</u> nickels 78 and dimes 22

Which sequences of transformations confirm the congruence of shape II and shape I?
mylen [45]

Answer:

1. When we reflect the shape I along X axis it will take the shape I in first quadrant, and then if we rotate the shape I by 90° clockwise, it will take the shape again in second quadrant . So we are not getting shape II. This Option is Incorrect.

2. Second Option is correct , because by reflecting the shape I across  X axis and then by 90° counterclockwise rotation will take the Shape I in second quadrant ,where we are getting shape II.

3. a reflection of shape I across the y-axis followed by a 90° counterclockwise rotation about the origin takes the shape I in fourth Quadrant. →→ Incorrect option.

4. This option is correct, because after reflecting the shape through Y axis ,and then rotating the shape through an angle of 90° in clockwise direction takes it in second quadrant.

5. A reflection of shape I across the x-axis followed by a 180° rotation about the origin takes the shape I in third quadrant.→→Incorrect option
