<h3>Answer:</h3>

2(c +1/9c +1/9c -7) . . . or . . . 22c/9 -14
$921.00

<h3>Step-by-step explanation:</h3>

(a) The cost of one set of curtains, shade, and rods is the sum of the costs of these separate items:

... set cost = c + 1/9c + 1/9c -7 = (1 2/9)c -7

Then the cost of 2 sets is ...

... 2 × set cost = 2((1 2/9)c -7) = (2 4/9)c -14 = 22c/9 -14

(b) Putting 382.50 into this expression where "c" is, then doing the arithmetic, gives ...

... cost of 2 sets = 22·382.50/9 -14 = 8415/9 -14 = 935 -14 = 921 . . . . dollars

Rewrite the following equation in slope-intercept form. 17x + 15y = 5 Write your answer using integers, proper fractions, and im

Answer:
y = $\frac{-17}{15} x$ + $\frac{1}{3}$

Explanation:
The slope-intercept form of the equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
17x + 15y = 5

To put it in the slope-intercept formula, we should isolate the y as follows:
17x + 15y = 5
15y = -17x + 5
y = (-17/15) x + (5/15)
y = $\frac{-17}{15} x$ + $\frac{1}{3}$
where:
m is the slope = -17/15
c is the y-intercept = 1/3

Hope this helps :)
