Answer:

$\boxed{\sf x= -29.5}$

Step-by-step explanation:

$\sf \sqrt{-2x+5}-3=5$

$\sf \sqrt{-2x+5}=8$

$\sf -2x+5=64$

$\sf -2x=59$

$\sf \cfrac{-2x}{-2}=\cfrac{59}{-2}$

Therefore, x = -29.5.

The area of the rectangle is 6 square feet. If its width is 2 1/7 feet, find its length.

densk [106]

Answer:

L = 2 4/5 feet

Step-by-step explanation:

A = L x W

6 = L x 2 1/7

divide both sides by 2 1/7

6 divided by 2 1/7 = L (is the same as multiplying by the reciprocal)

6 x 7/15 = L

L = 14/5 or 2 4/5

Which graph represents the function f(x)=

zhenek [66]

Step-by-step explanation:

you don't show us the choices.

anyway, the real graph must be similar to the one you are showing, as it goes to - and + infinity for x = 2.

because the denominator "x-2" will be 0 for x = 2.

but the horizontal limits are both y = +3 (and not 0).

because (3x-2)/(x-2) goes more and more to 3/1 the larger (or smaller in the - direction) x gets.

All students = 700

Sedaia [141]

Answer:

See below

Step-by-step explanation:

Given:

Total number = 700
Off grid class = 450
Online class = 320
Both = 275

Based on the given we find the following

1) Off-grid class only:

450 - 275 = 175

3) Online class only:

320 - 275 = 45

2) None of the classes:

700 - (175 + 275 + 45) = 205

4) Not online:

700 - 320 = 380

5) Not off-grid:

700 - 450 = 250
