Make a graph and put a point at exactly (1,2) and then make a like at y=3 make a line through the point and you'll see that this is an undefined equation x cant equal all those numbers
Answer:
3 cubic inches
Step-by-step explanation:
Volume of cone shown= 6 cubic inches
Let the base diameter be 2x.
Therefore, radius= x
Since the base diameter is the same, the base area is the same.
Using the formula, volume of cone
Subst. the known value of into the equation.
Thus, volume of cone= 1(3)= 3 cubic inches
Usando proporciones, hay que los $12,000 restantes deben ser investidos a una tasa de 11%.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total.
De las dos primeras inversiones, el ingreso es dado por:
0.08 x 15000 = $1,200.
0.09 x 22000 = $1,980
T = 1200 + 1980 = $3,180
Por la tercera inversión, busca-se un retorno de 4500 - 3180 = $1,320.
De esa forma, la tasa x es la seguiente:
12000x = 1320
x = 1320/12000
x = 0.11.
Los $12,000 restantes deben ser investidos a una tasa de 11%.

Answer:
3 because all the other are 2/3, C is 3/4
Step-by-step explanation:
Let the numbers be x and y
According to the data : xy=-15 and x+y=-7
xy=-15
x+y=-7
y=-7-x
x(-x-7)=-15
y=-7-x
-x^2-7x=-15
y=-7-x
x^2+7x-15=0
y=-7-x
x=(-7±sqrt(7*7+4*15))/2
y=-7-x
x=(-7±sqrt(109<span>))/2
</span>
Goes to two systems.
1)
y=-7-x
x=(-7+sqrt(109<span>))/2
</span>
y=-7+3.5-sqrt(109<span>))/2
</span>x=(-7+sqrt(109<span>))/2
</span>
y=-3.5-sqrt(109<span>))/2
</span>x=(-7+sqrt(109<span>))/2
</span>
2)
y=-7-x
x=(-7-sqrt(109<span>))/2
</span>
y=-7+3.5+sqrt(109))/2
x=(-7-sqrt(109))/2
y=-3.5+sqrt(109))/2
x=(-7-sqrt(109<span>))/2</span>
