You want to join a new pool. Beckett Pool charges a $90 membership fee and $25 per month. Lakota Hills Pool charges a $45 membership fee and $40 per month. After how many months is the total cost the same at both pools?

We can make an unlimited number of obtuse triangles when given two sides but no angle measurement, such as a = 10 and b = 8.

For illustration:

If we have side lengths of 10 and 8 and an angle value of 90 to 360 degrees, how many different obtuse triangles can we create?

Make a triangle with sides of 10 and 8 metres, an angle of 120 degrees, and a third side that may be adjusted to your preferred length using a protractor. You have built a triangle.

By changing the length and angle of the third side, we can produce a completely different triangle that is similar to this one.

It's imperative to keep in mind that you choose the side lengths and angle. It's implied that you could make a different decision. By employing the same angles, an unlimited number of different triangles can be formed.

Thus, using a single angle and a single side length, we may create an unlimited number of triangles.

Step-by-step explanation:

You can use any two points on a line to find slope. For example, I used:

(x1, y1) 2, -5

(x2, y2) 4, -4

To find slope, the following formula is needed:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Input our values:

The required value of the constant of proportion is 2.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion     —-- 1

Given the relation is y = 2x            —-- 2

On comparing both the equation 1 and 2, we have,

The three types of congruence transformations are rotation, reflection, and translation is TRUE.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

If we rotate a triangle by any angle in any direction either clockwise or anti the dimension will remain the same so it will be congruent.

If we reflect a triangle about any axis then also it will remain the same so it will be congruent.

If we transform by any amount either horizontal or vertical then it will remain the same so it will be congruent.

Step-by-step explanation:

Hello, and welcome to Brainly!

You are sometimes offered to find the distances between two points on a graph. But how are we to do this you ask?

The distance formula measures the distance in units from point A to point B. The formula is d=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where Point A is depicted as [tex](x_1, y_1)[/tex] and Point B is depicted as [tex](x_2, y_2)[/tex].

To start this problem, let's label a random point as A, and the other as B.

A: (-9, 3) where [tex]x_1=-9, y_1=3[/tex]
B: (-7, -4) where [tex]x_2=-7, y_2=-4[/tex]

Let's use the distance formula to solve this distance. Fill in the known variables.

d=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

d=[tex]\sqrt{(-7--9)^2+(-4-3)^2}[/tex]

[tex]d=\sqrt{(2)^2+(-7)^2}[/tex]                 Note that (-7--9) cancels out the two negatives and turns into (-7+9), which is 2.
[tex]d=\sqrt{4+49} \\d=\sqrt{53} \\d=7.2[/tex]

The distance between these two points is 7.2 units.

The rate of the growth of the Kudzu vine per day is,

The slope formula is,

[tex]m = \frac{(y _{2} - y _{1}) }{ (x _{2} - x _{1}) }[/tex]

[tex]m = \frac{4 - 0.5}{7 - 0} [/tex]

Rate of growth of Kudzu vine per day is 0.5 per day.

Let the height of the Kudzu vine after fifteen days be y2.

The height of the Kudzu vine after fifteen days is,

[tex]m = \frac{(y _{2} - y _{1}) }{ (x _{2} - x _{1}) }[/tex]

[tex]0.5= \frac{y _{2} - 0.5 }{15 - 0} [/tex]

Answer:

[tex]y = \dfrac{5}{2}x - 7[/tex]

Step-by-step explanation:

Step-by-step explanation:

Take any two points (x1, y1) and (x2, y2) from the table

Slope intercept equation is y = mx + b where m is slope and b = y-intercept

Slope = (y2-y1)/(x2-x1)

In this case

Let's choose the last two points

These are (6,  8) and (8, 13)

Slope = (13 - 8)/(8-6) = 5/2

So the equation is y = (5/2)x + b

To compute b, plug in x, y values for any point and solve for b

Choose the first point (0, -7)

Plug in:

-7 = (5/2)(0) + b

-7 = 0 + b or b = -7

So the equation of the line is
[tex]y = \dfrac{5}{2}x - 7[/tex]

We can verify by computing the y value for another point and seeing it agrees with table values

Choose point (4, 3)

y = 5/2 x 4 - 7

= 10 - 7 = 3

which agrees with the table value for y which is 3 when x = 4

Answer:  No, the sides do not form a right triangle.

============================================================

Explanation:

Let c = 20 be the largest or longest side. If we had a right triangle, then this side is the hypotenuse.

a = 14 and b = 15 are the other sides in either order.

Plug the values into the pythagorean theorem equation. Evaluate each side separately until getting a single numeric value.

[tex]a^2 + b^2 = c^2\\\\14^2 + 15^2 = 20^2\\\\196 + 225 = 400\\\\421 = 400\\\\[/tex]

The last equation is false, so the first equation is false for those a,b,c values mentioned. This shows us we do not have a right triangle.

For more information, check out the pythagorean theorem converse.

no

Does a triangle with sides 14, 15 and 20 can form a right triangle?

To check if a triangle is a right one, we can follow these steps:

Step 1: Take the longest side as the candidate for the hypotenuse (c). Here, the longest side is that of lenght 20. So, c = 20. The other sides are leg A (a) and leg B (b). In this case we can assume that a = 14 and b = 15 .

Step 2: Now plug in these values in the formula below to check its validity:

c2 = a2 + b2

202 = 142 + 152

400 ≠ 421

As both sides of the above equation are not equal, we can surely say that the triangle [14 15 20] is NOT a right triangle.

The solution of the given equation 7y + 4 = 3 - 2y is 29/2.

According to the given qestion.

We have a linear equation in one variable 7y + 4 = 3 - 2y.

So, the solution of the given linear equation in one variable  7y + 4 = 3 - 2y is given by

7y + 4 = 3 - 2y

⇒ 7y + 2y + 4 = 3    ( adding 2y both the sides)

⇒ 9y  = 3 - 4

⇒ 9y = -1

⇒ y = -1/9

Now, we will check whether y = -1/9 is the solution of the given equation 7y + 4 = 3 - 2y  or not.

Thereofore,

LHS

= 7(-1/9) + 4

= -7/9 + 4

= -7 + 36/9

= 29/9

Similarly

RHS

= 3 - 2(-1/9)

= 3 + 2/9

= (27 + 2)/9

By substitution, the solution of the system of equations, 4p + 2q = 8 and q = 2p + 1, is (p , q) = (3/4 , 5/2).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in p and q,

4p + 2q = 8     (equation 1)

q = 2p + 1     (equation 2)

Since the second equation is already expressed in q in terms of p, substitute the second equation to the first equation.

4p + 2q = 8     (equation 1)

4p + 2(2p + 1) = 8

4p + 4p + 2 = 8

Combining all terms containing the variable p on one side and the constants on the other side of the equality, and solving for p.

4p + 4p + 2 = 8

4p + 4p = 8 - 2

8p = 6

p = 6/8

p = 3/4

Substitute the value of p in the second equation and solve for q.

q = 2p + 1

q = 2(3/4) + 1

q = 6/4 + 1

q = 5/2

Hence, the solution of the given system of equations is (p , q) = (3/4 , 5/2).

divide the 24 by two so you can find one side of the two right triangles. you get 12. now that you have 12 and the 5 from the other side use a^2+b^2=c^2 to solve for the missing side where a=5 b=12 and c=? so 12 squares is 144 and 5 squared is 25 so add then up and you get 169=c^2. lastly square the 169 and you end up with 13 :)
