A line contains points M(1, 3) and N(5, 0). What is the slope of MN?
Answer:
-3/4
Step-by-step explanation:
y2-y1/x2-x1
0-3/5-1
A line contains points M(1, 3) and N(5, 0). The slope of MN is -3/4.
What is the slope of the line?A line's slope provides information on the steepness and direction of the line. By calculating the difference between the coordinates of the two locations, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them.
The slope, m, of the line, is calculated through the equation,
The formula used to find the slope is,
m = (y2 - y1)/ (x2 - x1)
Where (x1, y1) and (x2, y2) are the points
The given points on the line are:
M(1, 3) and N(5, 0)
Substituting it in the formula,
m = (0 - 3)/ (5 - 1)
m = -3/4
Therefore, the slope of MN is -3/4.

Skyler solved an equation incorrectly, as shown below:
Step 1: 12 + x = 36
Step 2: x = 36 + 12
Step 3: x = 24
Which statement best explains why Step 2 is incorrect in Skyler's solution?
Answer:
Step 2 is incorrect.
Step-by-step explanation:
It's incorrect because I'm pretty you need to do inverse operation. To get 24 you must subtract, not add.

The midpoint of a line segment is (−3,2). One endpoint of the line segment is (4,−7).
What are the coordinates of the other endpoint of the line segment?
Answer:
The other endpoint is (9, −6)
Step-by-step explanation:
(x1,y1)=(3,2) and M=(6,−2)
x1+x22=x and y1+y22=y
3+x22=6 and 2+y22=−2 ←×2
3+x2=12 and 2+y2=−4
x2=9 and y2=−6
The coordinates of the other endpoint of the line segment are [tex]Y(x,y) = (-10, 11)[/tex].
Vectorially speaking, the midpoint of a line segment is determined by the following expression:
[tex]M(x,y) = \frac{1}{2}\cdot X(x,y) + \frac{1}{2}\cdot Y(x,y)[/tex] (1)
Where:
[tex]M(x,y)[/tex] - Midpoint.[tex]X(x,y)[/tex], [tex]Y(x,y)[/tex] - Endpoints of the line segment.If we know that [tex]M(x,y) = (-3, 2)[/tex] and [tex]X(x,y) = (4, -7)[/tex], then the coordinates of the other endpoint is:
[tex]\frac{1}{2}\cdot Y(x,y) = M(x,y) -\frac{1}{2}\cdot X(x,y)[/tex]
[tex]Y(x,y) = 2\cdot M(x,y) -X(x,y)[/tex]
[tex]Y(x,y) = 2\cdot (-3,2)-(4,-7)[/tex]
[tex]Y(x,y) = (-6, 4) - (4, -7)[/tex]
[tex]Y(x,y) = (-10, 11)[/tex]
The coordinates of the other endpoint of the line segment are [tex]Y(x,y) = (-10, 11)[/tex].

A student uses the following steps to prove the sine sum identity. The proof is incorrect. Which steps is incorrect
Answer:
4
Step-by-step explanation:
The incorrect step is Step 4, cos (π/2 -x) cos(-y) + sin (π/2 -x)sin(-y), the correct option is C.
What is Trigonometric Identity?Trigonometric Identities are based on the trigonometric ratios used to solve Trigonometric equations.
The steps used to solve the trigonometric identity are :
Step 1 : sin(x+y)
Step 2: cos ((π/2) - (x+y))
Step 3 : cos ( (π/2 -x) -y)
Step 4 : cos (π/2 -x) cosy + sin (π/2 -x)siny
Step 5: sinxcosy+cosxsiny
Therefore,the correct step is cos (π/2 -x) cosy + sin (π/2 -x)siny and not cos (π/2 -x) cos(-y) + sin (π/2 -x)sin(-y) , the incorrect step is Step 4.

Answer:
A: 45
B: 110
C: 25
Step-by-step explanation:
all angles of a triangle always add together to make 180
x + 25 + x + 65 = 180
combine like terms
2x + 90 = 180
subtract 90 from both sides of the equation
2x = 180 - 90
divide both sides of the equation by 2
x = 90/2
x = 45
