Answer: 90 degrees counterclockwise and 270 degrees clockwise are the same things and you need to use the same formula for both

Step-by-step explanation:We swap the value of x and y and negate the value of y. So the value of x becomes the value of y and value of y becomes the value of x. so the formula is:

(x, y) –> (-y, x)

Before Rotation  After Rotation

(x, y)                    (-y, x)

Help needed ! 13 - 2(2x + 1) = 1 ?
kirill115 [55]

Answer:

x = ¹⁰⁄₄,⁵⁄₂, or 2.5

Step-by-step explanation:

Given: 13 - 2(2x + 1) = 1

1. Distribute -2 through the parentheses:

⇒ 13 - 2(2x + 1) = 1

⇒ 13 + (-2)(2x) + (-2)(1) = 1

13 - 4x - 2 = 1

2. Combine like terms:

⇒ 13 - 4x - 2 = 1

⟹ 11 - 4x = 1

3. Subtract 11 from both sides:

⇒ 11 - 11 - 4x = 1 - 11

⟹ -4x = -10

4. Divide both sides by -4:

⇒ -4x ÷ -4 = -10 ÷ -4

⟹ x = ¹⁰⁄₄,⁵⁄₂, or 2.5

5. Check your work:

⇒ 13 - 2(2x + 1) = 1

⇒ 13 - 2(2(2.5) + 1) = 1

⇒ 13 - 2(5 + 1) = 1

⇒ 13 - 2(6) = 1

⇒ 13 - 12 = 1

⟹ 1 = 1 ✔

Help me out here pleaseeeeeeee
puteri [66]

Answer:

12

Step-by-step explanation:

No. of planters = 4 ÷ \frac{1}{3}

To change the ÷ sign to a × sign, swap the denominators and numerators of the second fraction.

4 ÷ \frac{1}{3}  = 4 × \frac{3}{1}

Directly multiply.

4 × \frac{3}{1} = 12

Bob bought 24 hockey tickets for $83. Adult tickets cost $5.50, and child tickets cost $2.00. How many child tickets did he buy
Zepler [3.9K]

Answer:

14

Step-by-step explanation:

This can be solved by writing 2 equations and solving simultaneously.

Let <em><u>number of Adult tickets be A, and number of child tickets be C.</u></em>

<em><u /></em>

<u><em>"Bob bought 24 hockey tickets":</em></u>

A+C=24

<em><u>"Adult tickets cost $5.50, and child tickets cost $2.00...Bob bought 24 hockey tickets for $83":</u></em>

5.5A+2C=83

Now we can solve the first equation for A and substitute in 2nd equation and get the value of C.

A + C = 24

A = 24 - C

Now,

5.5 A + 2 C = 83

5.5 (24 - C) + 2C = 83

132 - 5.5C + 2C = 83

-3.5 C = 83 - 132

-3.5C = - 49

C = 14

Hence, Bob bought 14 child tickets

Which equation describes this line (1,13) (-2,4)
Sonja [21]

Answer:

D.

Step-by-step explanation:

First, you have to solve all of the options. The only option that makes since is D. To solve D, add 4 to both sides. That will leave you with y=3x+10. The slope of that equation is 3 and the y-intercept is 10. The line crosses the y-axis at 10, and goes up three and to the right one.
