Answer:

The correct answer is "y = 3/4x"

Step-by-step explanation:

Slope-intercept form is y2-y1/x2-x1. If you place the points into slope-intercept form you get 6-3/8-4. After reducing the fractions you will get 3/4. So the equation is y = 3/4x.

Answer:

(x, y) = (5, 2)

Step-by-step explanation:

Given:

LP = x

MP = 2y+3

NP = y+3

KP = 3x -8

KP = MP, LP = NP

Find:

x, y

Solution:

The given relations between the segment lengths let us write two equations:

KP = MP

3x -8 = 2y +3 ⇒ 3x -2y -11 = 0 [eq1]

LP = NP

x = y +3 ⇒ x -y -3 = 0 [eq2]

Subtracting 3 times [eq2] from [eq1] gives ...

(3x -2y -11) -3(x -y -3) = 0

y -2 = 0 . . . . . . . . simplify

y = 2 . . . . . . . . . . add 2

Substituting this value into [eq2] gives ...

x = 2 + 3 = 5

The values of x and y are ...

x = 5, y = 2

Determine the sum of the first 9 terms in the geometric series where r= -0.25 and a1= 256.

Damm [24]

$\bf \qquad \qquad \textit{sum of a finite geometric sequence} \\\\ S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ r=\textit{common ratio}\\ ----------\\ r=-0.25\\ a_1=256\\ n=9 \end{cases}$

$\bf S_9=256\left(\cfrac{1-(-0.25)^9}{1-(-0.25)} \right)\implies S_9=256\left( \cfrac{1+0.25^9}{1+0.25} \right) \\\\\\ S_9=256\left( \cfrac{52429}{65536}\right)\implies S_9=\cfrac{52429}{256}\implies S_9=204.80078125$

Suppose the a mountain bike that sells for $419 is on sale for 20.5% off.

nata0808 [166]

Regular price: $419
Sale price: (1-0.205)($419) = $333.11

The bike will cost $333.11 before tax. You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be

(1.00 + rate as a decimal fraction)*$333.11.

Example: If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).
