9xh = total cost of the hat 
9 per hat - 4 = $5 each scarf

h = hat 
s = scarf
(9xh) + (5x s)
(9x7) + (5x9) = 108

108 is the answer because each scarf is $5

Type the correct answer in the box. Use numerals instead of words.
Mandarinka [93]

Answer:

34

Step-by-step explanation:

We are here given a modulus expression and we need to find out the value when m = -5 and n = 3 .

<u>Modulus</u><u> </u><u>:</u><u>-</u> It always gives positive value . For example ,

\rm\implies |-a| = a

\rm\implies |a| = a

<u>The </u><u>given</u><u> </u><u>modulus </u><u>expression</u><u> is</u><u> </u><u>:</u><u>-</u><u> </u>

\rm\implies |m^2+ n^2|

As the number inside the modulus operator are already squared therefore they will always give positive value for real numbers . Here we can omit the modulus .

\rm\implies m^2 + n^2

Plug in the given values ,

\rm\implies (-5)^2 + 3^2

Solve 5² and 3² and add them ,

\rm\implies 25 + 9

On adding ,

\rm\implies 34

Therefore ,

\rm\implies \boxed{\blue{\rm |m^2+n^2| = 34 }}

<u>Hence</u><u> the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>34</u><u> </u><u>.</u>

Write an equation in point-slope form of the line that passes through the given point and with the given slope, m
bearhunter [10]
Equation format for a slope, m and a point (x1, y1)

y - y1  = m(x - x1)      (Try and memorize this formula)

8) for (3,-4),  m = 6.    x1 = 3,  y1 = -4, Substituting
y - y1  = m(x - x1)
y - (-4)  = 6(x - 3)
y + 4  = 6x - 18
y = 6x - 18 - 4
y = 6x - 22

10) for (-2,-7),  m = 4/5.    x1 = -2,  y1 = -7, Substituting
y - y1  = m(x - x1)
y - (-7)  = (4/5)*(x - (-2))
y + 7  = (4/5) *(x +2)                      4/5 = 0.8
y + 7  = 0.8x  + 1.6
y = 0.8x + 1.6-7
y = 0.8x - 6.4
y = (4/5)x - (64/10)
y = (4/5)x - (32/5)

So same approach to solve others. Cheers.
