-√5 ≈ -2.23 . . . . calculator

There are many ways to describe the result of a comparison of numbers: difference, percentage difference (using either as a base), greater/less than, ratio, and more.

We'll take the simplest, and say

... -1.96312 > -√5

Can someone help me with (a) and (c)? Thanks! ;D
BaLLatris [955]

Answer:

Step-by-step explanation:

a) Mark any two points in line a

(0,7)  ; (5,-3)

Find the slope

slope = y2 - y1 /x2-x1

=\frac{-3-7}{5-0}\\\\=\frac{-10}{5}\\\\=-2

Equation: y-y1 = m(x-x1)

y - 7 = -2(x - 0)

y - 7 = -2x

y = -2x + 7    --------> line a

c) equation of line b

(2,-1);  slope = -2  {as b line is parallel to line a}

y - y1 =m(x-x1)

y -(-1) = -2*(x - 2)

y + 1 = -2x - 2*-2

y + 1 = -2x + 2

y = -2x + 2 -1

y = -2x +1   ------> equation of line b

Robin can clean 72 rooms in 6 days how many rooms can robin clean in 9 days
galben [10]

Hello!

Robin can clean 72 rooms in 6 days. How many rooms can Robin clean in 9 days?

We have a proportional magnitude (directly proportional), if we increase the number of days for cleaning, obviously we will have more rooms cleaned, then:

clean rooms __________ days

72 ----------------------------------- 6

y ------------------------------------- 9

\dfrac{72}{y} = \dfrac{6}{9}

multiply the means by the extremes

6*y = 72*9

6\:y = 648

y = \dfrac{648}{6}

\boxed{\boxed{y = 108}}\Longleftarrow(clean\:rooms)\end{array}}\qquad\checkmark

Answer:  

108 clean rooms in 9 days

What are the slope of the y intercept of the line represented by the points shown on the table
Art [367]
The Y intercept is where the function passes/ intercepts the y axis. On a table, it is where x is 0, in this case the y intercept is -20. The slope is found by change in y over change in x. So choose any two coordinates to find change. 10/5=2. So your answer is A.
