GIVE OUT BRAINLY 2) Kathleen is a sales associate in a jewelry store. She earns $560/wk plus an 8% commission on sales. How much
aev [14]

700<=560+0.08x

x is total sales $

the 560 is the constant weekly pay, since we're only calculating for one week.

we're adding 0.08x to account for the 8% of the total sales

solve it for x:

700-560 <= 0.08x

140 <= 0.08x

1750 <= x

or x >= 1750

meaning she needs $1750 worth of sales that week to earn atleast $700

as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.

Can someone help me with my math I don't understand it
MArishka [77]

Answer:

  317°

Step-by-step explanation:

The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.

  (7x +1)° +90° +(9x -7)° = 180°

  16x = 96 . . . . . divide by °, subtract 84

  x = 6 . . . . . . . . divide by 16

Then angle AOD is ...

  (7·6 +1)° = 43°

Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.

  arc ACD = 317°

WILL MARK BRAINIEST!!!!!! Given: f(x) = 5x3 - x2 - 5x + 1
Vadim26 [7]

Answer:

steps below

Step-by-step explanation:

f(x) = 5x³ - x² - 5x + 1

Local extremes: 15x²-2x-5=0  .. gradient=0

x = (2 ± √2²-4*(15)*(-5)) / (2*15)

  = (2 ± √304) / 30

  = (2 ± 4√19) / 30

  = (1 ± 2√19) / 15

  = (1 ± 8.718) / 15

local maximum: (1 + 8.718) / 15 = 0.648

local minimum: (1 - 8.718) / 15 = - 0.515

the interval(s) where the graph is increasing: x < - 0.515 or x > 0.648

the interval(s) where the graph is decreasing: - 0.515 < x < 0.648

What does the expression 5n represent?
Brut [27]

Answer:

5 x n

Step-by-step explanation:

The variable n can be any number, so by saying 5n, you are multiplying 5 by that variable n.

Example below

If n = 1, 5n = 5*1 = 5

If n = 2, 5n = 5*2 = 10

If n = 3, 5n = 5*3 = 15

If n = 4, 5n = 5*4 = 20

Hope this helps!
