Answer:

I don't know how they answered your question before, but the answer for this is y = -44

Suppose y varies directly as x. Write a direct variation equation that relates x and y. Then solve.

y1/x1 = y2/x2

We know y1 = 22, x1 = 8, and x2 = -16. Thus:

22/8 = y/-16, or

y = [(22)(-16)]/8

Thus, by multiplication and division:

y = -44

I hope this helps!! Goodluck!!

Answer:

when I worked it out I actually got -1466...

Step-by-step explanation:

Using order of operations you would multiply the 2 by 742, then subtract from left to right. 2 x 742 =1484 and 30 minus that is -1454. Subtracting 12 would give you -1466. I know that's not in the answer choices but that's what I got...

Twins Bruno and Charlie both work at the same restaurant for an hourly rate. Bruno earns minimum wage as a dishwasher, while Cha
Ostrovityanka [42]

Answer:

The difference in their wages is because the quantity of output produced by a unit of labor is higher for a cook than a dishwasher and also because Bruno is an unskilled labor while Charlie can be categorised as a semiskilled labor.

Step-by-step explanation:

Bruno is a dishwasher

Charlie is a cook

Bruno earnings=$x

Charlie earns $2 more than his twin Bruno

Charlie earnings= $x+2.00

At the same restaurant for an hourly rate

The difference in the wages of Bruno and Charlie is as a result of the productivity of labor

The quantity of output produced by a unit of labor is higher for a cook than a dishwasher and also because Bruno is an unskilled labor while Charlie can be categorised as a semiskilled labor.

egoroff_w [7]
First group rate is x+10, Second is x
First group made 160, Second made 120
Time the first group will take is 160/x+10, and second is 120/x
Equation is: 160/x+10 + 4 = 120/x
x=10, x=-30
The second group made 10 suits everyday.

Y=6/13X is a proportional relationship
Ivan

Answer:

x in (-oo:+oo)

Y = (6/13)*x // - (6/13)*x

Y-((6/13)*x) = 0

Y+(-6/13)*x = 0

Y-6/13*x = 0 // - Y

-6/13*x = -Y // : -6/13

x = -Y/(-6/13)

x = 13/6*Y

x = 13/6*Y

Suppose a baby food company has determined that its total revenue R for its food is given by R = − x 3 + 39 x 2 + 945 x where R
Paraphin [41]

Answer:

35,000 units

Step-by-step explanation:

Total revenue is:

R = -x^3+39x^2+945x

The maximum revenue is attained at the production level for which the derivate of the revenue function is zero:

R = -x^3+39x^2+945x\\R'=0=-3x^2+78x+945\\x=\frac{-b\pm\sqrt{78^2-(4*(-3)*945)} }{-6}\\x_1=35\\x_2=-9

Since production cannot be negative, revenue will be at a maximum when x = 35, or when the production level is 35,000 units.
