Answer:
The answers are given below.
Step-by-step explanation:
2.
a) The range for Y - axis should be $ 12,000 to $ 19,500 while taking $ 500 denoting a unit length on the Y - axis. So, it will be in the scale ratio of ,
500 : 1 .
b)The step-size of the Y-axis can be taken to be 5 units per step, i. e., the marks are to be set at, 0 unit, 5 unit, 10 unit etc.
c) The range for X-axis should be, 0 to 10 years taking '0' mark on the base year which is the year, 10 years before from now and 1 year should be denoted by a unit length of X - axis. So, it will be in the scale ratio of 1 : 1 .
d)The step-size of the X-axis can be taken to be 2 units per step, i. e., the marks are to be set at 0 unit, 2 unit, 4 unit etc.
1) lavadora tipo A---> 3 tipos de carga, 5 colores, automatica o semiautomatica
Lavadora tipo A se puede elegir ------------- > 3*5*2=30 formas diferentes
lavadora tipo B---> 4 tipos de carga, 3 colores, automatica o semiautomatica
Lavadora tipo B se puede elegir ------------- > 4*3*2=24 formas diferentes
las dos lavadoras serian=30+24=54 maneras

Answer:
Step-by-step explanation:
y = -1/3x - 2....the slope here is -1/3....a perpendicular line will have a negative reciprocal slope....all that means is flip the slope and change the sign..
-1/3.....flip it.....-3/1....change the sign.....3/1 or just 3. So our line needs a slope of 3.
y = mx + b
slope(m) = 3
(1,4)...x = 1 and y = 4
now we sub and find b, the y int
4 = 3(1) + b
4 = 3 + b
4 - 3 = b
1 = b
so ur equation is : y = 3x + 1 <===
Value x as the weight of the large box, y as the weight of the small box
7x + 9y = 157 (1)
5x + 3y = 89 -> 15x + 9y = 267 (2)
(2) - (1) => 8x = 110
=> x = 13.75 kg
=> (1) => 5x13.75 + 3y = 89 => 3y = 20.25 => y = 6.75 kg
So, large box weigh 13.75 kg, and small box weigh 6.75 kg
Mark Brainliest if correct. :D
Answer:
3x + 22 = 82
Step-by-step explanation:
3x + 22 = 82
-22 = -22
3x= 60
3 = 3
X =20
