Answer:

x squared over 16 minus y squared over 25 equals 1

Step-by-step explanation:

x²/4² - y²/5² = 1

x²/16 - y²/25 = 1

The point D(2, -5) is rotated 90° counterclockwise around the origin. What are the coordinates of the resulting point, D′?
jeyben [28]

Answer:

D' = (5, 2)

Step-by-step explanation:

Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.

Define a variable. Write and solve each equation.
ella [17]

The answer is x = 6

Let us first define x to be the number of hours of riding lessons she can take.

X = Hours of lessons

Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:

200 - 20 - 30x = 0

Simplifying, we get

180 = 30x

x=6

line n passes through the points (-3, -7.5) and (2, -5). tahlia determined that the equation of line n is y = 0.5x. explain the

<h2>Therefore Tahlia made mistake. Tahlia did not write -6 in her equation.</h2>

Step-by-step explanation:

Given , line n passes through the points (-3,-7.5) and (2,-5)

x_1 = -3 , y_1=-7.5   and     x_2 = 2 , y_2=-5

Therefore the slope of the line is (m)  =\frac{y_1-y_2}{x_2-x_1}

                                                        =\frac{-7.5+5}{2+3}

                                                        =\frac{2.5}{5}   =\frac{1}{2}

Therefore the equation of line is

y-y_1=m(x-x_1)

\Leftrightarrow y+7.5 =\frac{1}{2}(x+3)

\Leftrightarrow y+7.5 = 0.5x+1.5

\Leftrightarrow y = 0.5x+1.5 -7.5

\Leftrightarrow y = 0.5x -6

Therefore Tahlia made mistake. Tahlia did not write -6 in her equation.
