Nikolay [14]3 years ago
7 0

Answer:

B) y = (-7X/5) + 4

Step-by-step explanation:

Recall two lines are perpendicular if their slopes are negative reciprocals (5/7 goes to -7/5).

Assuming in the form y = mx + b:

Solving for b:

-7/5(-5) + x = 11

(5's & negatives cancel out...)

7 + x = 11

x = 4

y = -7/5x + 4

El jefe de ventas comenta con tu padre que los 9.000 vehículos del mes pasado suponen unos buenos resultados, pero que este mes
Alja [10]

Answer:

900

Step-by-step explanation:

10% de 9000 es 900

Trabajando el 10% de 9000

Escribe 10% como 10100

Dado que, encontrar la fracción de un número es lo mismo que multiplicar la fracción por el número, tenemos

10100 de 9000 = 10100 × 9000

Por tanto, la respuesta es 900

Si está utilizando una calculadora, simplemente ingrese 10 ÷ 100 × 9000, lo que le dará 900 como respuesta.

A grocery store has a shelf with half-gallon containers of milk. What type of number best represents the total number of gallons
Veronika [31]
As a number, half-gallon can be represented as 0.5.
In order to answer this question we will define each term:

whole numbers are numbers that can be defined as a <span>number without fractions which are greater or equal than 0. E.g. 2 0 1 5 6 85
</span>
integer numbers are numbers that can be defined as a number without fractions but which can be either equal to 0 or greater and lower than 0
E.g. -9 -68 8 0 59

rational numbers are  any number that<span> can be expressed as a fraction p/q of two integers E.g. 0.5 = 1/2 1 = 1/1 1.25 = 5/4
</span>
irrational numbers are those which have an approximate value E.g. pi = 3.14...
√2 = 1.41.....

real numbers are all of the above

From all those kind of choices the most accurate representation is rational numbers.
