The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.
SVEN [57.7K]

Answer:

n = -3

Step-by-step explanation:

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.

I'm going to call the number "n."

n² - 24 =  5n      subtract 5n from both sides to get the equation equal to zero

- 5n        -5n

n² - 5n - 24 = 0   factor the trinomial into the multiplicatin of two binomials

                          we need factors (numbers that multiply) to -24 that add up to

                          -5.  The only factors for -24 that will add up to -5 are -8 and 3.

(n-8)(n+3) = 0     set each binomial equal to zero and solve for n

n-8  =  0     or    n+3  =  0

 +8    +8               -3     -3

 n   =  8     or        n  = -3       n = -3 is the negative solution

4x+y=10 missing value
hoa [83]

Answer:

Step-by-step explanation:

Set each axis to 0

4(0)+y=10

y=10

4x+0=10

divide the equation by 4

x=2.5

if both axis' need to be the same number, they are equal to 2

Given the table of data, determine the function that would most appropriately model the data. x 0 1 2 3 f(x) 1.5 2 2.5 3 linear
azamat

Answer:

  linear

Step-by-step explanation:

The x-values are evenly spaced (1 apart), so it is helpful to look at the differences of the f(x) values.

Successive f(x) values all differ by the constant 0.5, a characteristic of a linear function.

_____

<em>Comment on differences</em>

The differences of successive y-values are called "first differences". The differences of those are called "second differences". And the differences of those are "third differences." The "degree" of the differences that are constant is the degree of the function describing the sequence.

That is, a sequence (like this one) with constant first differences can be described by a first-degree polynomial, a linear function. If third differences are constant, the sequence is described by a third-degree polynomial, a cubic function.

A square root function will have first differences that decrease by a decreasing amount. Successive differences of differences will continue to decrease, never becoming constant.

An exponential function will have first differences with a common ratio.
