Slope is 1/2

Step-by-step explanation:

How I learned it: Rise/ Run

Hope that helps!

Answer:

1/2

Step-by-step explanation:

Slope is defined as rise over run. In the graph, you can see that for every 2 units in the positive x-direction, there will be 1 unit in the positive y-direction. Therefore, the answer is change in x/change in y = 1/2

Answer:

[tex]90 \sqrt{2} [/tex]

Step-by-step explanation:

This is a 45°-45°-90° right triangle, so the length of the hypotenuse is √2 times the length of a leg. Since both legs have length 90, the hypotenuse has length 90√2. So y=90√2.

Answer:

-3x + 4 = 2

just find x

Step-by-step explanation:

x = ⅔

Answer:

Unlike the previous problem, this one requires application of the Law of Cosines.  You want to find angle Q when you know the lengths of all 3 sides of the triangle.

Law of Cosines:  a^2 = b^2 + c^2 - 2bc cos A

Applying that here:

                          40^2 = 32^2 + 64^2 - 2(32)(64)cos Q

Do the math.  Solve for cos Q, and then find Q in degrees and Q in radians.

Step-by-step explanation:

Answer:

x = 30

Step-by-step explanation:

this is an isosceles triangle, which mean that PRQ and PQR are equal.

all sides of a triangle equal 180.

using this, you can make the following equation:

x + (2x + 15) + (2x + 15) = 180

combine like terms

5x + 30 = 180

subtract 30 from both sides

5x = 150

divide both sides by 5

x = 30

Your answer is: y= -2x+7

Step-by-step explanation:

Hope this helped : )

The equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7

The formula for calculating the equation of a line is expressed as y = mx+ b

m is the slope of the line

b is the y-intercept

Given the coordinate points (8, -9) and (-4, 15)

Get the slope of the line;

[tex]m =\frac{15-(-9)}{-4-8}\\m=\frac{24}{-12} \\m = -2[/tex]

Get the y-intercept of the line

Recall that y = mx + b

15 = -2(-4) + b

b = 15 - 8

b = 7

Get the required equation in the form y = mx + b

y = -2x + 7

Hence the equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7

Answer:

The first choice is correct. ii only.

Step-by-step explanation:

A rigid transformation changes the location of the shape without changing its size. There are three basic rigid transformations: reflections, rotations, and translations.

We are given these properties:

i. Increases or decreases the size of the figure

ii. Moves the location of the figure.

iii. Changes the shape of the figure.

Let's analyze each choice below:

O ii only . This is true. The other two properties are non-rigid transformations. Correct

O i and ii . This is not true. Increasing or decreasing the size of the figure is a non-rigid transformation. Incorrect.

O ii and iii. Changing the shape of the figure is a non-rigid transformation. Incorrect.

O i, ii, and iii. Properties i and iii are non-rigid transformation. Incorrect.

Step-by-step explanation:

The hyperbola with one focus point in common with the given hyperbola is:

[(y + 11)² / 10²] - [(x - 7)² / 15²] = 1

To find a hyperbola that shares one focus point with the given hyperbola, we need to find another hyperbola with the same focus point but different characteristics (e.g., eccentricity or axis length).

The equation of the given hyperbola is:

[(y + 11)² / 15²] - [(x - 7)² / 8²] = 1

The general equation of a hyperbola with its center at (h, k) is:

[(y - k)² / a²] - [(x - h)² / b²] = 1

The center (h, k) of the given hyperbola is (7, -11).

To share one focus point, we need to keep the center at (7, -11) but change the values of a and b. The eccentricity of a hyperbola is defined as e = c / a, where c is the distance from the center to the focus.

Let's assume the new hyperbola has an eccentricity different from the given hyperbola. We'll keep the same value of c and change the value of a to get a different eccentricity.

Let's say the new hyperbola has a value of a' = 10. Since the eccentricity is different, the value of b' will change accordingly. Let's calculate b' using the eccentricity formula:

e = c / a'

15 / 10 = 1.5

Now, we can find b' using the eccentricity:

e = c / a' = c / 10

c = e * a' = 1.5 * 10 = 15

Now, we have the center (7, -11), the value of a' = 10, and the value of c = 15. The equation of the new hyperbola with one focus point in common is:

[(y + 11)² / 10²] - [(x - 7)² / 15²] = 1

The range of the function c = 50t + 200 is given by [200, ∞).

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

Let c represent the distance travelled in t hours, hence:

c = 50t + 200

The range of the function c = 50t + 200 is given by [200, ∞).
