Answer:
A.
Step-by-step explanation:
Simplify the radical by breaking up the radicand up into a product of known factors, assuming positive real numbers.
M= y2-y1?x2-x1
m=4-(-1)/(-7)-8
m=5/-15
m=-3
The slope is -3
It’s ba + 2b - 2a + ab
B times a is ba
B times b is 2b
-a times a is -2a
-a times -b is ab
Whenever it’s a negative and a positive, it will be a negative integer or letter.
But when there’s two negatives will be a positive integer or letter.
Plug in for x.
7(2y - 4) + 5y = -66
14y - 28 + 5y = -66
19y - 28 = -66
19y = -38
y = -2
Put it back into the equation.
2(-2) - 4 = -8
x = -8
The x-value is x = -8
Respuesta:
1000m³
Explicación paso a paso:
La capacidad del tanque viene dada por el volumen del cubo;
El volumen, V del cubo se da como: a³
V = a³
El borde del cubo mide 10 metros.
Por eso,
Volumen = 10³
Volumen = 10 * 10 * 10
Volumen = 1000 m³
Por lo tanto, la capacidad del tanque de agua es de 1000 m³.
