Consider the system of equations.

Mathematics
1 answer:
Xelga [282]3 years ago
3 0

Answer:

D and C

Step-by-step explanation:

Given the 2 equations

3x - y = 5 → (1)

2x + 3y = - 15 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

9x - 3y = 15 → (3)

Add (2) and (3) term by term to eliminate y

11x + 0 = 0

11x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

The value of an industrial machine has a decay factor of 0.75 per year. After six years, the machine is worth $7,500. What was t
Digiron [165]
If the value was initially v, then after a year it is 0.75v, after 2 years it’s 0.75²v, and so on. So after 6 years it’s 0.75⁶v.
So 0.75⁶v=7500, and v=7500/0.75⁶=$42,139.92 approximately. This is close to $42,140.

Masteriza [31]

Answer:

  • All four of the remaining faces will be 4 inches wide.

Step-by-step explanation:

A right rectangular prism with square base and top with sides of 4 in.

It has four sides of 4 in wide each and of equal height of unknown measure.

<u>Options:</u>

All four of the remaining faces will have a height of 4 inches.

  • Incorrect, the height is unknown.

There is not enough information to tell what the other faces will look like.

  • Incorrect, all the other faces are rectangular.

Two of the remaining faces will be 4 inches wide.

  • Incorrect, all the faces are 4 in wide.

All four of the remaining faces will be 4 inches wide.

  • Correct.

A skyrocket is launched from a 30–foot-high platform, with initial speed 300 ft/s. If the polynomial −16t2 + 300t + 30 gives the
Stella [2.4K]

Answer:

566 ft

Step-by-step explanation:

Given the polynomial equation

-16t² + 300t + 30 = 0

We're asked to find how high the rocket would rise in a 2 second fuse rise. This is a simple instruction that can be obtained by setting the unknown, t, in the equation to 2. Doing this, we have

-16 * 2² + 300 * 2 + 30

-16 * 4 + 600 + 30

-64 + 630 = 566 ft

Then, we can therefore conclude that the rocket will rise high up to a distance of 566 ft

Can someone please help i dont understand
Sloan [31]

Answer:

x = 12

Step-by-step explanation:

Angle 1 = 8x - 17

Angle 2 = 5x + 19

These are congruent which means they are the same so the equation is:

8x - 17 = 5x + 19

3x - 17 = 19

3x = 36

x = 12
