please help guys no spam :( The total amount of money (in cents) in x dimes, (x+2) nickels, and 2x quarters. The total amount of money is ____ cents. (Hint: value of a dime is 10 cents, nickel is 5 cents, and a quarter is 25 cents.)

Answer :

five x plus ten

Answer:

x=2 and y=11

Step-by-step explanation:

Okay so subtitution method

y=5x+1

2y-6x=10

Plug in the y

2(5x+1

)-6x=10

10x+2-6x=10

4x+2=10

4x=8

x=2

now plug in for y

lets use first equation

y=5(2)+1

y=10+1

y=11

Answer:

d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))

Step-by-step explanation:

To find the derivative of f(t), we have to find the derivative of each component of the function to make it easier.

d(8/(t^7))/dt = d(8xt^-7)/dt = –7 x 8 x t^-8 = –56t^-8 = -56/(t^8)

d(5/(t^(1/6)))/dt = –(1/6) x 5 x t^(-7/6) = –(5/6)/t^(7/6)

d(3t^4)/dt = 4 x 3 x t^3 = 12t^3

d(t²)/dt = 2t

d(t^⅓)/dt = ⅓t^(-2/3) = (1/3)t^(2/3))

d(12)/dt = 0.

Therefore,

d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))

Answer: d≤69

Step-by-step explanation:

You would plug in all the values for d into the inequality

40(81) + 240 ≤ 3000

40(81) + 240 = 3000

3240+240=3000

3480=3000 false

40(75) + 240 ≤ 3000

40(75) + 240 = 3000

3000+240=3000

3240=3000 false

40(69) + 240 ≤ 3000

40(69) + 240 = 3000

2760+240=3000

3000=3000 true

You don't need to try the last one because you already found this one!

The inequality expresses the maximum number of days Marisa can pay the expenses for her bike trip will be d ≤ 69.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Marisa saved $3000 to take a bike trip from Florida to California.

She estimated her expenses to be $40 per day.

The cost of a ticket to fly back is $240.

The inequality below can be used to find the maximum number of days (d) for which Marisa can pay the expenses on the bike trip.

40d + 240 ≤ 3000

Substitute all the values for d into the inequality

For, d≤81

40(81) + 240 ≤ 3000

40(81) + 240 = 3000

3240+240=3000

3480=3000 false

For, d≤75

40(75) + 240 ≤ 3000

40(75) + 240 = 3000

3000+240=3000

3240=3000 false

For, d≤69

40(69) + 240 ≤ 3000

40(69) + 240 = 3000

2760+240=3000

=3000

therefore, LHS = RHS

Hence, d ≤ 69 is true.

Answer:A

Step-by-step explanation:

The vertex of the image L'(6,8) is the greatest distance from the origin.

When a graph is reflected along an axis, say the x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.

Since each point is equidistant from the axis of reflection as that of the image of that point. Thus, if we reflect a point (x,y) along the x-axis, then its x abscissa will stay the same but y ordinates will negate. Thus (x,y) turns to (x, -y)

Given that a triangle with vertices L (-2,5), E (1,4), and D (2,-2) is translated 4 units left, 3 units up, and then reflected over the line y=4 to form the image triangle L’E’D'.

If we subtract 4 from each x number and add 3 to each y number and then reflect over the line y=4 so then that would give each distance.

L (-2,5) --  L (-2 - 4,5 - 4 )

L'(6,8)

Resulting that L'(6,8) being the farthest from the origin (0,0)
