Vertex formula = -b/2a
-18/1 = 18.
However, this is just the x value, the vertex is (x,y)
-18*2 + 18(18) - 72 = 576

Complete the point slope equation of the line through(-1,-10)and(5,2).<br>y-6=

Lynna [10]

Answer:

Step-by-step explanation:

The point-slope of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the poinys (-1, -10) and (5, 2). Substitute:

$m=\dfrac{2-(-10)}{5-(-1)}=\dfrac{12}{6}=2$

Put the value of the slope and the coordinateso f the point (5, 2), to the equation of a line:

$y-2=2(x-5)$

In the question we have y - 6 = ...

Therefore

$y-2=2(x-5)$ <em>subtract 4 from both sides</em>

$y-6=2(x-5)-4$ <em>use the distributive property</em>

$y-6=2x-10-4$

$y-6=2x-14$ <em>distributive</em>

$y-6=2(x-7)$

The distance y (in centimeters) a spring is compressed by a force x (in kilograms) is given by

kirza4 [7]

Answer:

(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}

Graph C represents the table of values

Step-by-step explanation:

To complete the table, substitute each value of x into the equation, $y = 0.065x$ , to find each corresponding y-value.

Thus:

✔️When x = 20:

$y = 0.065x$

$y = 0.065(20)$

$y = 1.3$

✔️When x = 40:

$y = 0.065x$

$y = 0.065(40)$

$y = 2.6$

✔️When x = 60:

$y = 0.065x$

$y = 0.065(60)$

$y = 3.9$

✔️When x = 80:

$y = 0.065x$

$y = 0.065(80)$

$y = 5.2$

✔️When x = 100:

$y = 0.065x$

$y = 0.065(100)$

$y = 6.5$

✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>

Solve for 3+y/2=-212

Lyrx [107]

You have the following equation:

$3+\frac{y}{2}=-212$

In order to solve the previous equation for y, proceed as follow:

3 + y/2 = -212 subtract 3 both sides

y/2 = -212 - 3 simplify right side

y/2 = -215 multiply by 2 both sides to cancel the denominator left side

y = -215(2)

y = -430

Hence, the solution for y in the given equation is y = -430
