In a certain year, the average e-mail user sent or received 114 e-mails each day. The number of e-mails received was 6 more then
Tems11 [23]

Answer:

78 emails

Step-by-step explanation:

Given

Represent sent emails with x and received with y.

So, we have:

x + y = 114 -- First statement

y = 6 + 2x -- Second statement

Required

Determine the number of emails received (y)

Make x the subject in x + y = 114

x = 114 - y

Substitute 114 - y for x in y = 6 + 2x

y = 6 + 2(114 - y)

Open bracket

y = 6 + 228 - 2y

Collect Like Terms

2y+y = 6 + 228

3y = 234

Divide by 3

y = 234/3

y = 78

For the functions f(x)=−7x2−x and g(x)=9x2−4x, find (f−g)(x) and (f−g)(1).
siniylev [52]

Step-by-step explanation:

f(x) = -7x² - x

g(x) = 9x² - 4x

(f - g)(x) = (-7x² - x) - (9x² - 4x)

(f - g)(x) = (-7x² - 9x²) + (-x + 4x)

(f - g)(x) = -16x² + 3x

(f - g)(1) = -16(1)² + 3(1)

(f - g)(1) = -16.1 + 3

(f - g)(1) = -16 + 3

(f - g)(1) = -13
