Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

Over her 17 day winter break, Lindsay want to read the last book in the Harry Potter seriees, which has 759 pages. If she reads
Alex Ar [27]

Answer: Yes, she will finish before winter break is over.

Explanation:

Since we have given that

Number of days in winter break = 17

Number of pages she read in each day = 75

Number of pages in the Harry Potter series she wants to read = 759

Now, we'll use unitary method,

in 1 day , she read = 75 pages

in 17 days , she read is given by

17\times 75=1275\text{ pages}

and 759 pages is less than 1275 pages.

So, she will finish before winter break is over.

If 5+6i is a root of the polynomial function f(x),which of the following must also be a root of f(x)
Lostsunrise [7]
The complex conjugate root theorem states that if a+bi (with a and b being numbers) is a root, then a-bi is also a root. Plugging that in here, this means that 5-6i is also a root
