The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7

HELP...... rewrite the equation by completing the square.<br> x ^2 +10x+16=0
Sonbull [250]

Answer:

(x+5)^{2} = 9

Step-by-step explanation:

To complete the square you need to add \frac{b}{2}^{2}to both sides. (Parenthesis around b/2)

b = 10

b/2 = 5

(b/2)^2 = 25

x^{2} +10x + 16 = 0

subtract 16 to both sides

x^{2} + 10x = -16

add 25 to both sides

x^{2} +10x + 25 = 9

Perfect Square Trinomial Factoring

(x+5)^{2} = 9

Answer:

the y-value of the vertex = 1,125

Step-by-step explanation:

The table is as shown at the attached figure.

By graphing values in an x-y plane and observe the graph.

From the illustration, locate the vertex. The vertex of the parabola is (5, 1,125). So, the y-value of the vertex of the parabola that models the data is 1,125.

See the graph between x and y.
