a) The linear equation to find the price p of a share of XYZ Corporation stock w weeks from now is p = 3w + b

b) Price of a share of stock five weeks ago is $ 65

<em><u>Solution:</u></em>

The equation of line (in slope intercept form) is given as:

y = mx + b

Where "m" is the slope and "b" is the y - intercept

<u><em>The equation of a line for price p of a share of XYZ Corporation stock w weeks from now is:</em></u>

p = mw + b

where y = the price of the stock, w = weeks, m is the slope and b is the y-intercept and "p" is the price of share

Given that  price of a share of stock in XYZ Corporation was $74 two weeks ago. Seven weeks ago, the price  was $59 a share

So we have two points (-2, 74) and (-7, 59)

<em><u>The slope "m" can be found as:</u></em>

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\text{ here } x_1 = -2 ; y_1 = 74 ; x_2 = -7 ; y_2 = 59

\begin{aligned}m &=\frac{59-74}{-7-(-2)} \\\\m &=\frac{-15}{-5}=3\end{aligned}

Thus the equation becomes:

p = 3w + b

To find b, plug in either known point:

Substitute (w, p) = (-2, 74)

74 = 3(-2) + b

74 = -6 + b

b = 80

Thus equation becomes:

p = 3w + 80

<em><u>b. Estimate the price of a share of stock five weeks ago</u></em>

Here w = -5

p = 3(-5) + 80

p = -15 + 80

p = 65

Thus price of a share of stock five weeks ago is $ 65

BC is parallel to DE<br> What is AC?
DaniilM [7]
ΔABC ~ ΔADE
AC/AE = AB/AD
AC/(AC+15) = 8/18
18AC = 8(AC+15)
18AC = 8AC + 120
18AC - 8AC = 120
10AC = 120
AC = 120/10
AC = 12

Jabian buys pencils as souvenirs from his vacation to give to his friends. He starts with 90 pencils and gives away 15 each hour
Sidana [21]
You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.

"starts with 90 pencils" implies that the y-intercept is (0,90).

"gives away 15 pencils" implies a slope of -15 pencils per unit of time

Thus, the # of pencils Jabian still has is   P(x) = 90 - (15 pencils / time unit)x
