WRITE AN EQUATION TO DESCRIBE THE RELATIONSHIP BETWEEN J AND Mj | 4 | 12 | 20m | 3 | 9 | 15
galina1969 [7]

First, we can use the points (4,3) and (20,15) to find the slope of the line:

\begin{gathered} s=\frac{m_2─m_1}{j_2─j_1}=\frac{15─3}{20─4}=\frac{12}{16}=\frac{3}{4} \\ s=\frac{3}{4} \end{gathered}

Now we can find the relation function using the point (4,3) and the slope s=3/4

\begin{gathered} m─m_1=s(j─j_1) \\ \Rightarrow m─3=\frac{3}{4}(j─4)=\frac{3}{4}j─(\frac{12}{4})=\frac{3}{4}j─3 \\ m=\frac{3}{4}j \end{gathered}

therefore, the equation to describe the relationship between J and M is m=3/4j

Is a triangle with two congruent sides always have 45 45 and 90 degrees?
Alex Ar [27]
No.  Two angles will have to be the same and the third angle will just be 180° minus twice the smaller angles.

So if we let the equal angles equal a, and the large angle equal be we have:

2a+b=180

So there are infinitely many values that a and b can have.

a=(180-b)/2, so the smaller equal angles have the range (0,90)

b=180-2a, so the larger has a range of (0,180)

The midpoint of segment ST is M(5,2). One endpoint is S(-1, -7). Find the coordinates of the other endpoint.
Tasya [4]

Answer:

The other endpoit has this cordinadetes (11, 11).

Step-by-step explanation:

Midpoint (MD) (Xm, Ym)

Xm = 5

Ym = 2

Xm of the Midpoint:    Xm = X1 + X2/ 2

Ym of the Midpoint:    Ym = Y1 + Y2/2

<em>We can say that S is (x1, y1), so x1 = -1 and y1 = -7</em>

Then:

Xm = -1 + x2/2

5= -1 + x2/2

10 = -1 + x2

x2 = 11

Also:

Ym = -7 + y2/2

2 = -7 + y2/2

4 = -7 + y2

11 = y2

Suppose 29 cars start at a car race. In how many ways can the top 3 cars finish the​ race?
Ilia_Sergeevich [38]

any of the 34 cars can finish first  

any of the remaining 33 cars can finish second

any of the remaining 32 cars can finish third  

 

Thus, the top 3 finishes can be done in (34)(33)(32) = 35904 ways
