In this problem, the point-slope form of a line is defined as:
Where:
represents a point on the line,
and m stands for the slope.
Given the details:
Substitute the values:
Thus, the equation of the line is:
Answer:
Triangle MRN is created when an equilateral triangle is folded in half. Triangle N R M is shown. Angle N R M is a right angle. A
n altitude is drawn from point R to point S on side M N to form a right angle. The length of N S is 6, the length of S M is 2, the length of R M is x, the length of N R is y, and the length of R S is z. What is the value of x? 2 StartRoot 3 EndRoot units 4 units 4 StartRoot 3 EndRoot units 8 units

Answer:
El valor de x es 4.
Explicación paso a paso:
Se indica que el triángulo MRN surge al doblar un triángulo equilátero por la mitad.
Esto sugiere que el triángulo equilátero original es MNO y que NR actúa como bisectriz perpendicular (una línea que divide un segmento en dos partes iguales formando un ángulo recto).
La longitud del lado del triángulo es
NO = NS + SM = 6 + 2 = 8
Dado que un triángulo equilátero tiene todos sus lados iguales y NR es la bisectriz perpendicular, se tiene que
RM = MO/2 = 8/2 = 4
El valor de x es 4.

Answer:
The price per kilogram of salami amounts to = $9.1
Step-by-step explanation:
Given:
Hailey spent $13 on kg of sliced salami.
We need to determine the cost per kg of the salami.
Solution:
We will use the unitary method to find the cost for one kilogram of salami.
If kg of salami costs $13
Then the cost for 1 kg of salami in dollars =
When dividing mixed numbers, we convert them to fractions.
⇒
⇒
To divide fractions, we take the reciprocal of the divisor and multiply.
⇒
⇒
⇒
⇒
Hence, the cost per kilogram of salami is = $9.1
