Write an equation in slope intercept form to model the situation.

Answer:

y=-\frac{1}{2}x + 10

Step-by-step explanation:

Slope intercept form is a way of modeling a quadratic equation, where the coefficient of the term (x) is the slope (change) of the line, and the constant is the y-intercept. In essence;( y=mx+b ), where (m) is the slope and (b) is the y-intercept.

The slope of the given line is (-\frac{1}{2}) because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is (\frac{1}{2}) because this is the rate of burning, the slope is also negative since the height is decreasing. (10) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is (y=-\frac{1}{2}x + 10), where the output (y) is the current height of the candle, and the input (x) is the time at which the measruement was taken.

If n = 11 and p = 5 what is the value of the expression 18 - n - 2 + p
yan [13]

Answer:

10

Step-by-step explanation:

If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.


The new equation would be 18 - 11 - 2 + 5.

Using PEMDAS, we get the answer of 10.  

18 - 11 = 7

7 - 2 = 5

5 + 5 = 10


Hope this helps!

May I please get help with my math lesson if possible I don't know why they are 4 answers if 1 of the answers don't apply to any
Doss [256]

Answer: S1:E7 ; S2:E1 ; S3:E5

Step-by-step explanation:

What we know:

  • 3 answers apply
  • We need to find which answers go with each question

**A lot of info is problem-specific.

How to solve:

Since we only need to write the equations, we simply need to find the x and y variables, and the total.

Process:

Problem 1:

  • Find the x                                                                     5.50
  • Find the y                                                                     3
  • Find the total                                                                145
  • Write equation                                                      5.50 + 3 = 145

Problem 2:

  • Find the x                                                                     2.50
  • Find the y                                                                     0.75
  • Find the total                                                                25
  • Write equation                                                      2.50 + 0.75 = 25

Problem 3:

  • Find the x                                                                     2
  • Find the y                                                                     5
  • Find the total                                                                50
  • Write equation                                                        2 + 5 = 50

Solution: S1:E7 ; S2:E1 ; S3:E5
