What does X equal. HELP PLEASE!!

Mathematics
1 answer:
Anton [14]3 years ago
4 0

Answer:

x=3

Step-by-step explanation:

8x-28-2x=-10

We move all terms to the left:

8x-28-2x-(-10)=0

We add all the numbers together, and all the variables

6x-18=0

We move all terms containing x to the left, all other terms to the right

6x=18

x=18/6

x=3

Mar 12: 3
erastovalidia [21]

Answer:

  • Mar 18: 125
  • Mar 19: 318
  • Mar 20: 743
  • Mar 25: 15,070

Step-by-step explanation:

The six seemingly arbitrary points have no common difference or ratio, so cannot be modeled by a linear or exponential function.

The differences of the differences are not constant at any level, so the only polynomial model is 5th-degree. It is ...

  (6n^5 -95n^4 +600n^3 -1825n^2 +2814n -1320)/60

where n = days after Mar 11. (Mar 12 corresponds to n=1.) The domain is n ≥ 1.

____

The 5th-degree polynomial increases very fast, but not as fast as an exponential function would.

The values for Mar 12 through Mar 25 are ...

  3, 8, 11, 16, 25, 50, 125, 318, 743, 1572, 3047, 5492, 9325, 15070

On a diagram of the arena, the car park's length is 15 cm. The scale is 1:100.
faltersainse [42]

If a diagram has a scale of 1:100, that means that the real thing is 100 times larger. To find how long the real thing is, that means that we need to multiply the length on the diagram by 100. 100 * 15 is 1500. But, that is 1,500 cm. To convert it into meters, we need to divide by 100. That's because there's 100 centimeters in every meter. 1500/100 is 15, which means that the actual length of the car park is 15 meters.

Jeremy’s pay started at a $500 per week. Every year his pay will increase by $25 per week. Write an equation that models his wee
algol [13]

Answer:

W = 500 + 25x

Step-by-step explanation:

Jeremy’s pay started at $500 per week. Every year his pay will increase by $25 per week.

Now, after x years his pay per week will increase by $(25x).

Therefore, if we model the weekly payment of Jeremy by an equation, then it will be given by

W = 500 + 25x

where W is his weekly payment after x years. (Answer)

The standard form of the equation of a parabola is y = x2 - 8x + 29. What is the vertex form of the equation?
Bess [88]
Y = x² - 8x + 29
y = (x² -8x +4²) + 29 -4² . . . . add and subtract the square of half the x-coefficient
y = (x -4)² + 13 . . . . . . . . . . . . simplify

The appropriate choice is
  C. y = (x - 4)² + 13
