Circle 1's center is at x=-4 and Circle 2's center is at x=5. To translate Circle 1 to Circle 2, we need to shift the circle to the right 9 places:

5 - (-4) = +9

We do the same thing for the y value. We are going from y=-2 to y=3.

3 - (-2) = +5

So the first blank is (9, 5)

Next, the scale factor refers to the factor at which the circle is stretched or shrunk. We find it by comparing the radii. Going from 3 cm to 6 cm, the scale factor is:

6/3 = 2.

The scale factor is 2.

Given that 2(-x + 4)=3 prove that x=5/2

user100 [1]

Answer:

x = 5/2

Step-by-step explanation:

So firstly, you want to distribute. It'll make your life much easier.

-2x + 8 = 3

-2x = -5 (subtracting 8 from both sides)

x = 5/2 (dividing both sides by -2 to obtain x)

Hope this helps :)

How many sides does this regular polygon have? <br>Pls help

galina1969 [7]

Answer:

9 sides

Step-by-step explanation:

7y + 2y = 180

9y = 180

y =20

so, 2y, the exterior angle is 2 x 20 = 40

Divide 360 by 40 = 9

First we need to determine the type of progression in the question.
That's geometric progression. Because the pattern from one sequence to the others are about multiplying.

Second, determine the ratio of the progression
r = a₂/a₁
r = a₂ ÷ a₁
r = 1/2 ÷ 2
r = 1/2 × 1/2
r = 1/4

Third, determine the formula to know the recursive rule
a₂ = a × 1/4
a₂ = 1/4 × a
$a_{n} = \frac{1}{4} a_{(n-1)}$

Fourth, determine a₁. a₁ is the first term of the progression
a₁ = 2

Final answer:
Recursive rule
$a_{n} = \frac{1}{4} a_{(n-1)}$
a₁ = 2
