Answer:

  D.  J(x) = 1/4(-x)^3

Step-by-step explanation:

Reflection across the y-axis replaces x with -x. Then if Fr(x) represents the reflected function, we have ...

  Fr(x) = (-x)^3.

Compression by a factor of c < 1 multiplies the function value by c. Then ...

  J(x) = 1/4·Fr(x)

  J(x) = (1/4)(-x)^3

Answer:

[tex](x - 6)(x + 5) = {x}^{2} - x - 30 \\ or \\ a {x}^{2} + bx + c\\ {x}^{2} +( x_{1} + x_{2}) x + x_{1} .x_{2} \\ b = x_{1} + x_{2} = 5 - 6 = - 1 \\c = x_{1} .x_{2} = - 6 \times 5 = - 30 \\ \therefore \: {x}^{2} - x - 30[/tex]

Answer:

Step-by-step explanation:

D = Donuts

B = Brust cut

P = Profit

B - 12D = $3

12D = $12 a donut, used $3 since it didnt say more than 3.

Plug it in

B - 12(10) = $3

B - 120 = 3

  +120    +120

B= $123

If Brust had 1/4 of the profit, do 4B to find profit

4B = P

4(123) = P

P = $492

Algebros made $492 selling fidget spinners.

The minimum possible profit for Algebros would be $60

An inequality in mathematics compares two values or expressions, showing if one is less than, greater than, or simply not equal to another value. The general equation of a straight line inequality is -

[y] < [m]x + [c]

[y] > [m]x + [c]

[y] ≥ [m]x + [c]

[y] ≤ [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line inequality can be also written as -

Ax + By + C > 0

By > - Ax - C

y > (- A/B)x - (C/A)

Given is Brust who took his cut (one-fourth) of the Algebros profit from selling fidget spinners to the store and bought 10 donuts for $12. He came home with more than $3.00.

Assume that Algebros had made $x profit. Then, we can write the  inequality as -

x/4 - 12 > 3

On solving, we get -

x/4 > 15

x > 60

Therefore, the minimum possible profit for Algebros would be $60

Answer:

Step-by-step explanation:

314+175= 489 round that it would be 500 so it would be less than 600

Please mark me brainliest

Hello there!

The sum of 314 and 175 = 489.

If we round it, we will get 500.

500 is less than 600.

So the sum of 314+175 is less than 600.

Hope this helps you!

Answer:

Sydney will be 154.94cm

Answer:

38 meters below sea level.

Step-by-step explanation:

if the sub dives 155 BELOW sea level, this equals -155.

then it RISES 117 meters, which equals +117.

we can make this into an  equation

-155+117=-38!

the location of the sub is 38 meters below sea level.
