How Long will it take each student plan to be paid down to $1000?
Alex_Xolod [135]

The corresponding answers for each student plan are:

plan A: 15 years

plan B: 5 years

plan C: 10 years

plan D: 9 years

Thus, first, the graph corresponding to each of the plans must be analyzed. The Y-axis corresponds to money and the x-axis corresponds to the time in years.

Thus, in-plane A, it can be observed that to reach the desired value, the graph will be projected in exponential, so it will be close to 15 years. In plan B, this projection will be reached around 5 years. In plans C and D, this projection will be 10 years and 9 years respectively.

(SUPER EASY ANSWER QUICK 30 POINTS!)
harina [27]

\frac{35}{4} feet below the surface

adding the 2 quantities

3 \frac{1}{2} + 5 \frac{1}{4}

= (3 + 5 ) + (\frac{1}{2} + \frac{1}{4})

= 8 + (\frac{2}{4} + \frac{1}{4})

= 8 + \frac{3}{4} = 8 \frac{3}{4} = \frac{35}{4}

NEED THIS ASAPWrite the standard form of the equation of each line given the slope and y-intercept
Mama L [17]

<em>Note:</em>

<em>Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.</em>

                                            Question 2

Answer:

The equation in the standard form is:

  • 2/3x + y = -4

Please also check the attached graph.

Step-by-step explanation:

We know that the equation in the standard form is

Ax + By = C

where x and y are variables and A, B and C are constants

Given

  • Slope m = -2/3
  • y-intercept = -4

To determine

  • Write the equation in the standard form

We know that the slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

In our case:

  • Slope m = -2/3
  • y-intercept = -4

substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation

y = mx+b

y = -2/3x  + (-4)

y = -2/3x - 4

Writing the equation in the standard form

2/3x + y = -4

Therefore, the equation in the standard form is:

  • 2/3x + y = -4

Please also check the attached graph.
