-2.2+0.3z = 3-0.5z-0.8z

-2.2 = 3-0.5z-0.8z-0.3z

-5.2 = -1.6z

z = -5.2 / -1.6

z = -3.25

-2.2 + 0.3z= 3 -0.5z -0.8z \\ \\ 0.3z - 2.2 = 3 - 0.5z - 0.8z \\ \\ 0.3z - 2.2 = 3 - 1.3z \\ \\ 0.3z = 3 - 1.3z + 2.2 \\ \\ 0.3z = -1.3z + 5.2 \\ \\ 0.3z + 1.3z = 5.2 \\ \\ 1.6z = 5.2 \\ \\ z = 3.25 \\ \\

The final result is: z = 3.25.

Given b(x) = [X+41, what is b(-10)?<br> – 10<br> -6<br> 6<br> 14
OLEGan [10]

Option C: 6 is the value of b(-10)

Explanation:

The given expression is b(x)=|x+4|

We need to determine the value of b(-10)

To find the value of b(-10), let us substitute x=-10 in the given expression.

Thus, substituting x=-10 in the expression, we have,

b(-10)=|-10+4|

Adding the terms, we get,

b(-10)=|-6|

Since, we know the absolute rule that |-a|=a and the simplified expression is of the form |-a| , let us apply the absolute rule in the simplified expression.

Thus, we have,

b(-10)=6

Thus, the value of b(-10) is 6.

Hence, Option C is the correct answer.

Answer quick find the coordinates
Mekhanik [1.2K]

Answer:

  (-4, -3), (4, -1), (8, 0), (12, 1)

Step-by-step explanation:

The x- and corresponding y-values are listed in the table. Put each pair in parentheses, <em>x-value first</em>. (That is an <em>ordered pair</em>.)

  (x, y) = (-4, -3) . . . . from the first table entry

  (x, y) = (4, -1) . . . . from the second table entry

  (x, y) = (8, 0) . . . . from the third table entry

  (x, y) = (12, 1) . . . . from the last table entry
