Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

To begin with, let's convert this problem into an equation as displayed below:

Let certain number = x

59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7

59 / 7 - ( x + 8 / 7 ) = 19 / 7

59 / 7 - x - 8 / 7 = 19 / 7

- x = 19 / 7 - 59 / 7 + 8 / 7

- x = - 32 / 7

x = 32 / 7

ANSWER:

Therefore, the certain number is 32 / 7.

Hope this helps! <3

11. Find all relative extrema for f(x) = 3x + 7x2 + x +5.
igomit [66]

Answer:

Rel. Minimum- -0.3

Rel. Maximum - None

Increasing on: -0.3, infinity

Decreasing on: -Infinity, -0.3

Step-by-step explanation:

f(x) = 3x + 7x2 + x +5

To find the relative minimum, punch the equation into your graphing calculator and you should get -2/7 as your minimum. (Divide it for a decimal number)

There is no relative maximum because of this parent function type.

Increasing on: -2/7, infinity

And Decreasing on: -infinity, -2/7

MrMuchimi

Answer:

Okay so, one pen equals to 25p, one rubber equals to 10p, and Erica bought a pencil, a rubber, and a ruler for 1 pound, which means 25p+10p equals to 35p, and 100-35= 65p, so one ruler costs 65p, so Horace bought a pencil, a ruler and a pen, we know one pencil equals 25p, a ruler costs 65p, and a pen also equals 25p, so 25+65+25 = 115, so 1pound 15 p
