What value of x makes the equation true?

Mathematics

Answer:  The correct option is

(A) -4.

Step-by-step explanation:  We are given to find the value of x that makes the following equation true :

1.4x+2.6x=-16~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the value of x, we must solve the given equation.

The solution of equation (i) is as follows :

1.4x+2.6x=-16\\\\\Rightarrow (1.4+2.6)x=-16\\\\\Rightarrow 4x=-16\\\\\Rightarrow x=-\dfrac{16}{4}\\\\\Rightarrow x=-4.

Thus, the required value of x is -4.

Option (A) is CORRECT.

x= -4 because 1.4 times -4=- 5.6 and 2.6 times -4=-10.4 and when we add to numbers postive or negative numbers it stays positive or negative depnding on the problem and 10.4 + 5.6 + 16 however becuase both were negative the answers stays negative making the answer _ 16 and it says 1.4x+2.6x=-16 so the correct answer is x= -4

Find the following <br> (u•w)(2)=<br> (w•u)(2)=
Viefleur [7K]

Answer:

(u \circ w)(2) = -34

(w \circ u) = -49

Step-by-step explanation:

We are given these following functions:

u(x) = 4x + 2

w(x) = -5x + 1

The first step to solve this question is finding the composite functions. So

(u \circ w)(x) = u(w(x)) = u(-5x+1) = 4(-5x + 1) + 2 = -20x + 6

(w \circ u)(x) = w(u(x)) = w(4x + 2) = -5(4x+2) + 1 = -20x - 9

At x = 2

Now we replace x by 2 in each of the functions. So

(u \circ w)(2) = -20(2) + 6 = -40 + 6 = -34

(w \circ u)(2) = -20(2) - 9 = -40 - 9 = -49
