Step-by-step explanation:
Graph the solution of the inequality
we know that
The solution is the interval ---> (-∞,-4]
All real numbers less than or equal to -4
In a number line the solution is the shaded area at left of t=-4 (closed circle, because the number -4 is included in the solution))

Answer:
0.4kg, 1.4kg and 1.8kg
Step-by-step explanation:
Given parameters:
Mass of alloy = 3.6kg
Ratio of elements in the alloy = 2:7:9
Unknown:
Mass of each element in the alloy = ?
Solution:
To find the mass of each element in the alloy, first find the sum of the ratio;
2+7+9 = 18
Mass of nickel = x 3.6 = 0.4kg
Mass of zinc = x 3.6 = 1.4kg
Mass of copper = x 3.6 = 1.8kg
The mass of each metal is 0.4kg, 1.4kg and 1.8kg
It follows from the definition of the derivative and basic properties of arithmetic. Let <em>f(x)</em> and <em>g(x)</em> be functions. Their derivatives, if the following limits exist, are
The derivative of <em>f(x)</em> + <em>g(x)</em> is then
