Answer:

m∠DBC = 86°

Step-by-step explanation:

Find the variable, x.  First, combine like terms. Like terms are terms with the same amount of the same variable:

3x + 4x + 67 + 50 = 180

(7x) + (117) = 180

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis,

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 117 from both sides of the equation:

7x + 117 (-117) = 180 (-117)

7x = 180 - 117

7x = 63

Next, divide 7 from both sides of the equation:

(7x)/7 = (63)/7

x = 63/7 = 9

x = 9

Next, plug in 9 for x in the angle DBC:

m∠DBC = 4x + 50

             = 4(9) + 50

             = 36 + 50

             = 86°

m∠DBC = 86°

5) Consider the equation : y=7x+8
vekshin1

The correct students about the function are;

B: The function represented by the table has a greater rate of change.

C: The function y = 7x + 8 has the greatest  y-intercept.

<h3>How to Interpret the Function Table?</h3>

We are looking at the equation;

y = 7x + 8

The general equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, the slope of the given equation is 7 while the y-intercept is 8.

From the table, the rate of change which is also  is simply the slope from the formula;

m = (y₂ - y₁)/(x₂ - x₁)

m = (32 - 16)/(4 - 2)

m = 8

Looking at the given options, only options that are correct are Options B and C.
