Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?

Mathematics
1 answer:
Eduardwww [97]3 years ago
3 0

Step-by-step explanation:

<em>Look at the picture.</em>

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

d=\sqrt{x^2+y^2}

W(-3, 4)

d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5

(3, -4)

d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5

(4, 3)

d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5

(-4, -3)

d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5

(-4, 3)

d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5

Mama L [17]

Answer:

$91.75

Step-by-step explanation:

Jessica is paid:

  • $0.45 per basket for the first 100 baskets picked;
  • $0.50 per basket for all baskets over 100 picked.

1st day:

Jessica picked 65 baskets of oranges (less than 100)

Jessica is paid 65\cdot \$0.45=\$29.25

2nd day:

Jessica picked 135 baskets of oranges (35 more than 100)

Jessica is paid 100\cdot \$0.45+35\cdot \$0.50=\$45+\$17.50=\$62.50

Altogether Jessica is paid

\$29.25+\$62.50=\$91.75

Jason has 208 baseball cards. This is 52 less than the number of cards that Robert has.
V125BC [204]

Answer:

B) R - 52 = 208

Step-by-step explanation:

Robert has 52 more cards than Jason, who has 208, so Robert has 208 + 52 cards. This can be turned into:

R = 208 + 52

then subtract 52 from both sides:

R - 52 = 208 + 52 - 52

R - 52 = 208

and that's the answer

What is the value of y if (4y + 8) - (7y - 12) = 11? (PLEASE ANSWER + 10 POINTS!!!!)?
lyudmila [28]
Hello!

(4y + 8) - (7y - 12) = 11     is     1(4y + 8) - 1(7y - 12) = 11

1(4y + 8) - 1(7y - 12) = 11               Given
        4y + 8 - 7y + 12 = 11              Distribute the 1 and the -1
                    -3y + 20 = 11             Combine like terms
                            -3y = -9              Subtract 20 from both sides
                               y = 3                Divide both sides by -3

Answer:
y = 3
