D. Inverse property
Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents...
L=2w-1, lw=45
(2w-1)w=45
2w²-w-45=0
((w-5)(2w+9)=0
w=5
l=9
Answer:
Option B.
Step-by-step explanation:
From the picture attached, figure above the x-axis is the pre-image and below the axis is the image.
Let's choose a point B of the image having coordinates (0, 2).
When the point B is transformed, coordinates of the point B' is (0, -2)
And the rule for this transformation will be,
(x, y) → (-x, -y)
This rule shows the reflection of pre-image over the origin.
Option (B). will be the answer.
Answer: x = 58°
Step-by-step explanation:
Sine = opposite leg ÷ hypotenuse
We need to find the hypotenuse first with the Pythagorean theorem.
a² + b² = c²
5² + 8² = c²
25 + 64 = c²
89 = c²
√c² = √89
c = 9.43398
c ≈ 9.43
Sine = opposite leg ÷ hypotenuse
Opp. leg - 8
Hypotenuse - 9.43
To find this, you have to use the calculator
Make sure the calculator is on scientific
If your calculator is on your computer and in full screen, find 8 ÷ 9.43 and then click sin⁻¹, you should get 58.03334
If your calculator is on your computer in mini screen, find 8 ÷ 9.43. This time, click the arrow that looks smth like this: ↑
When you do that, you should be able to see sin⁻¹, so you click that and you'll also get 58.03334
58.03334 ≈ 58
x = 58°

Answer:
Thus to rent <u>10</u> number of videos to get the cost same.
Step-by-step explanation:
Given:
Michael's Video charges member $4 to rent each video. If you get a store membership it costs $20 and members only pay $2 to rent a video.
Now, to find the number of videos to get the cost same.
Let the number of videos to get the cost same be
Charges to rent each video without membership = $4.
Cost of membership = $20.
Charges to rent each video with membership = $2.
Now, to get the number of videos to get the cost same we write and solve an equation:
<em>Subtracting both sides by </em><em> we get:</em>
<em /><em />
<em>Dividing both sides by 2 we get:</em>
Therefore, to rent 10 number of videos to get the cost same.
