$\\ \tt\hookrightarrow a/3=-5a$

$\\ \tt\hookrightarrow a=-15a$

Only 0 can be the solution

$\\ \tt\hookrightarrow 12-b=12.5b$

$\\ \tt\hookrightarrow 12=13.5b$

$\\ \tt\hookrightarrow b=12/13.5$

$\\ \tt\hookrightarrow b=0.8$

$\\ \tt\hookrightarrow -0.1=-10c$

$\\ \tt\hookrightarrow 10c=0.1$

$\\ \tt\hookrightarrow c=0.01$

Answer:

a = -15, b = -.5, c = -1

Step-by-step explanation:

1/3a = -5 --> multiply each side with 3 --> a = -15

12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5

.1 = -10c --> multiply each side with -10 --> c = -1

The person is a member for super for a female boss over in the and loss increased approximately linearly from 5% in 1974 to 9% i

natali 33 [55]

Answer:

1998

y=6x+1944

Step-by-step explanation:

The percentage of Male workers who prefer a female boss over a male boss increased approximately linearly from 5% in 1974 to 9% in 1998. Predict when 9% of male workers will prefer a female boss

it is explicit from the question that 9% of male workers prefer female boss in 1998. but we can predict a model for this by getting the slope of the graph

y=the year

x=the percentage of men who prefer a female boss

s=y2-y1/(x2-x1)

s=1998-1974/(9-5)

s=24/4

s=6

therefore we have

y=mx+c

y=6x+c........1

when y=1998,x=9

1998=6(9)+c

c=1944

from equation 1

y=6x+1944

in Mr. Rodgersd' Social Studies class the stuents took a test. The scores on the test were: 95, 85, 75, 90, 70, 95, 85, 80, 75,

Anettt [7]

The correct answer would be A) 80 because if we organize all the tests scores from smallest numbers to biggest, and cross out numbers from each side, and keep going till one is left, we see 80 is the last number in the middle. *below is a image of my work.

Given the function f(x)=x^4+8x^3+18x^2+7 determine the absolute minimum value of f on the closed interval [-4, 1].

Blababa [14]

Answer: 7

Step-by-step explanation:

To find the absolute minimum we must first take the derivative of the function and find where it equals zero. From there we can use the first derivative test to find where our possible minimum is. We then will test each endpoint and compare for the minimum for this function.

$f(x)=x^4+8x^3+18x^2+7\\f'(x) = 4x^3+24x^2+36x\\\\4x^3+24x^2+36x = 4x(x^2+6x +8)\\\\x = 0\\x = -4\\x = -2\\\\f(-4) = 39\\f(-2) =31\\f(0) = 7\\f(1) = 34$

The lowest value is 7. The absolute minimum of this function is 7. If you were to graph it, we'd see that the graph reflects that as well.
