Answer:
Step-by-step explanation:
<u>slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Given line: y= 2x +2
slope= 2
The product of the slopes of perpendicular lines is -1. Let the slope of the unknown line be m.
m(2)= -1
m= -1 ÷2
m= -½
Substitute the value of m into the equation:
y= -½x +c
To find the value of c, substitute a pair of coordinates.
When x= 4, y= 3,
3= -½(4) +c
3= -2 +c
c= 3 +2
c= 5
Thus, the equation of the line is y= -½x +5.
Answer: If you want to make more cookies then what is called for in this situation then you would need <u><em>6 cups of milk.</em></u>
Step-by-step explanation: You have 2 cups of milk and 3 cups of flour of course. In order to make a complete batch you need 2 cups of milk and 3 cups of flour. In order to make a second batch you need the same things as you did for the first batch. Therefore two batches of cookies requires 4 cups of milk and 6 cups of flour. In this situation you want to make 3 batches of cookies. The required items are <u><em>6 cups of milk</em></u> and 9 cups of flour.
Answer:
tropic music = $8 million
and
urban latin music = $4 million
and
pop/rock music = $15 million
Step-by-step explanation:
given data
total revenues = $27 million
to find out
How much revenue was earned from digital sales in each of the three categories pop/rock , tropical and urban Latin music
solution
we consider here sale by pop/rock = P
and tropical T = x
and then urban Latin U =
then P = x + + 3
so we have given
P + T +U = $27 million ........................1
x+ + x + + 3 = 27
2x + x + 2x+ x+ 6 = 54
x = 8
so
tropic music = $8 million
and
urban latin music = $4 million
and
pop/rock music = 8 + + 3 = $15 million
Answer:
Si el metro cuadrado es a $ 50 Alejadro pagó por el terreno $195 000
Step-by-step explanation:
Ya que no se especifica un valor por unidad de área podemos suponer por ejemplo $ 50 / metro^2
Terreno:
0.3 hm^2
0.9 dam^2
1) Vamos convertir a la misma unidad de área las áreas del terreno para poder saber su costo.
-Hectómetro cuadrado
1 hm^2 = 10 000 m^2
Por lo tanto,
0.3 hm^2 * 10 000 m^2 / 1 hm^2 = 3000 m^2
-Decámetro cuadrado
1 dam^2 = 1 000 m^2
Por lo tanto,
0.9 dam^2 * 1 000 m^2 /1 dam^2 = 900 m^2
Así que el total del terreno es de 3900 m^2
2) Ahora podemos calcular el valor total del terreno
area* valor (por m^2)
3900 m^2 * $50/ m^2 = $195 000
