Find x and y intercept and plot
set x to zero and find y
set y to zero and find x
tada, 2 points

if x=0, then y=-4
if y=0, then x=-16
we havee the points
(0,-4) and (-16,0)

or
y=-1/4x-4

Daniel looks at the prices of 5 guitars. The prices are $137, $159, $127, $188 and $680. These prices contain one extreme value
brilliants [131]

Answer:

D. Mean absolute deviation

Step-by-step explanation:

Median gives us : 159

Range gives us: 680 - 127 = 553

mean gives us :

127+137+159+188+680 = 1291

1291 / 5

= 258.2

MAD gives us the mean deviation (avg change from the mean):

mean

= 258.2

258.2 - 127 =131.2

258.2 - 137 =121.2

258.2 - 159 =99.2

258.2 - 188 =70.2

680 - 258.2

=421.8

Find the mean of the variances:

70.2+99.2+121.2+131.2+421.8 = 843.6

843.6 / 5

= 168.72

Mad = 258.2 +- 168.72

Which is the simplified form of the expression (6-4)-9
Veseljchak [2.6K]

I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>

First you had to calculate with parenthesis first.

(6-4)=2-9

Then you add and subtract from left to right.

2-9=-7

Final answer \boxed{=-7}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

X²+x=0<br> x³-25x=0<br> x²=4x<br> 4x²-4x=1
-BARSIC- [3]

Answer:

x²+ x = 0

x ( x +1 ) = 0

x = -1

x³-25x=0

x ( x² - 25 ) = 0

x² = 25

x = 5

x²=4x

x² - 4x = 0

x ( x- 4 ) = 0

x = 4

4x²-4x=1

4x²-4x - 1 = 0

4 x² - 2x - 2x - 1 = 0

2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0

2x- 1 ) ² = 0

2x = 1

x = 1/ 2
