A perpendicular line has a negative reciprocal of a given line.


The given slope is 1/3, the reciprocal of this would be 3/1, which simplifies to 3.

The negative of 3 is -3.


The answer is a) -3.

Which line has a slope of 0.625, and which line has a slope of 1.6?
kirill115 [55]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b; where y and x are variables, b is the y intercept (i.e. value of y when x is zero), m is the slope of the line.

The slope of a line passing through the points (x_1,y_1)\ and\ (x_2,y_2)\ is:

m=\frac{y_2-y_1}{x_2-x_1}

Let the point where the two lines intersect be the origin (0, 0).

Line 1 passes through (0, 0) and (8, 5). Hence:

slope of line 1 = \frac{y_2-y_1}{x_2-x_1}=\frac{5-0}{8-0} =0.625

Line 2 passes through (0, 0) and (5, 8). Hence:

slope of line 2 = \frac{y_2-y_1}{x_2-x_1}=\frac{8-0}{5-0} =1.6

Summarize the possible relationships for the y -intercepts, slopes, and number of solutions in a system of two linear equations
ale4655 [162]

A consistent system of equations has at least one solution.

A consistent system is considered to be an independent system if it has a single solution, such as the example we just explored. The two lines have different slopes and intersect at one point in the plane.

A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line. Every point on the line represents a coordinate pair that satisfies the system. Thus, there are an infinite number of solutions.

Another type of system of linear equations is an inconsistent system, which is one in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no points common to both lines; hence, there is no solution to the system.

FInd the surface area of the triangular prism
Marta_Voda [28]

Answer:

273.7

Step-by-step explanation:

first fine the sides that isn't the base.

triangle area formula: (b*h)/2

(14*9)/2 = 63

since there are 3 sides you multiply this by three.

63*3=189

then find the base.

same formula since its a triangle.

(12.1*14)/2 = 84.7

now add them both up:

84.7+189 = 273.7

hope this helps!
