It’s b because negative 9 turns into positive 9 to cancel out the number to isolate variable. Then you also add positive 9 to 15 and that makes 24. But don’t forget about 4x which divide into 4x/4 and 24/4 to again isolate the variable. Then 24/4 = 6

4x - 9 = 15

Add 9 on both sides (-9 + 9 cancels out and 15 + 9 = 24)

4x = 24

Divide by 4 on both sides (4 / 4 cancels out and 24 / 4 = 6)

x = 6

<u>The answer is B</u>

Construct a linear equation for the linear data presented in the table
yaroslaw [1]

Answer:

y = -7x

Explanation:

Take two points from table: (-4, 28), (-3, 21)

Find slope:

\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\rightarrow \sf slope\ (m):   \dfrac{21-28}{-3-(-4)}  = -7

Now find equation:

\sf y - y_1 = m (x - x_1)

\rightarrow \sf y - 21 = -7(x - (-3))

\rightarrow \sf y  = -7(x +3) + 21

\rightarrow \sf y  = -7x -21 + 21

\rightarrow \sf y  = -7x

How do graphs and equations reveal information about a relationship between two quantities
ohaa [14]
When two quantities have a relationship, there is a corresponding equation that could describe it. These two quantities may be expressed in variables of x and y. When you plot the graph, you may see a line or a curve. This presents the trend of the relationship of the two quantities when the independent variable changes.

Please help meee and show all steps please!!!ty
kolbaska11 [484]

Answer:

x = -4 and x = 5

Step-by-step explanation:

Since x^2 + 2x and 3x + 20 both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

x^2 + 2x = 3x + 20

Now we solve the equation.

x^2 + 2x = 3x + 20

x^2 - x = 20

x^2 - x - 20 = 0

(x + 4) (x - 5) = 0

x + 4 = 0 ; x -5 = 0

x = -4 ; x = 5
