8. Write the equation of a line that is perpendicular to the given line and that passes through the

avanturin [10]

Y - 3 = 8/3(x + 2)...the slope here is 8/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3/8

y - y1 = m(x - x1)
slope(m) = -3/8
(-2,3)....x1 = -2 and y1 = 3
now we sub
y - 3 = - 3/8(x - (-2)...not done yet
y - 3 = -3/8(x + 2) <===

Answer:

$y=-4x+5$

Step-by-step explanation:

Step 1: Find the slope

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

$m=\frac{13-5}{-2-0}$

$m=-\frac{8}{2}$

$m=-4$

Step 2: Use point slope form

$(y-5) = -4(x-0)$

$y-5 + 5=-4x + 5$

$y=-4x+5$

Answer: $y=-4x+5$

Modern Appliances offers a one-year monthly installment plan for a refrigerator. The payment for the first month is $75, and the

Elena-2011 [213]

First month payment = $75
The amount to pay increases compound for the next 11 months

Number of months left on the instalment plan is 11 months

The increase is 6% = 0.06

Let F be final value and X be the value paid at the beginning of instalment, then

$F=X (1+0.06)^{n}$ , where 'n' is the number of months left to be paid

$F=75 (1.06)^{11} =142.4$
