Select the linear equation represented in the graph.

AleksAgata [21]

Answer:

$y = \frac{1}{2} x + 3$

Step-by-step explanation:

use y = mx + b

slope(m) = $\frac{1}{2}$

y-intercept(b) = 3

so,

$y = \frac{1}{2} x + 3$

1. If quadrilateral ABCD is rotated 270° clockwise about the origin, find the coordinates of B'.

Zielflug [23.3K]

Answer:

The coordinates of B' are (-3, 5).

Step-by-step explanation:

For every 90 degrees rotated, the coordinate numbers switch and one is multiplied by -1, when clockwise it's the 2nd one, and when counterclockwise, it's the 1st.

The generic equation of the line is:

$H-H0 = m (T-T0)$

Where,

m: slope of the line

(T0, H0): ordered pair belonging to the line.

The slope of the line is:

$m =\frac{H2-H1}{T2-T1}$

Substituting values we have:

$m =\frac{15-17}{5-3}$

Rewriting:

$m =\frac{-2}{2}$

$m = -1$

Then, choosing an ordered pair we have:

$(T0, H0) :( 5, 15)$

Substituting values we have:

$H-15=-(T-5)$

Rewriting the equation:

$H-15=-T+5$

$H=-T+5+15$

$H=-T+20$

Then, for 8 hours we have:

$H=-8+20$

$H=12$

Answer:

a linear equation to model the relationship between height H of the candle, and T time is:

$H=-T+20$

the candle will be 12 inches after burning 8 hours
