What is the slope of the line?<br> 2x - 5y = 9<br> Choose 1 answers<br> 5<br> 2<br> O
Zepler [3.9K]

9514 1404 393

Answer:

  D.  2/5

Step-by-step explanation:

The slope is the x-coefficient when the equation is solved for y.

  2x -5y = 9 . . . . . . . given

  -5y = -2x +9 . . . . . .subtract 2x

  y = (-2/-5)x +9/(-5) . . . . divide by -5

  y = 2/5x -9/5

The coefficient of x is 2/5. That is the slope of the line.

The slope is 2/5.

To describe a specific arith-
Bezzdna [24]

Answer:

f(x) = 7x + 30

Step-by-step explanation:

We need at least two points to write the equation of a straight line.

The recursive formula that Elijah wrote is:

f(0) = 30

f(n + 1) = f(n) + 7

When we substitute n=0, we get:

f(0 + 1) = f(0) + 7

f(1) = 30 + 7

f(1) = 37

The points (0,30) and (1,37) lies on this line.

The equation of this line is of the form:

f(x) = mx + b

where b =30 is the y-intercept and m=7 is the slope.

We plug in these values to get:

f(x) = 7x + 30

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.

You could also use the two points to find the slope:

m =  \frac{37 - 30}{1 - 0}  = 7

Scan domain, range and graph of the following functions:
FinnZ [79.3K]
Sorry can't include the graphs, just subsitute y for f(x) and graph by subsituting values


so domain is the set of numbers you are allowed to use
range is the set of number you get from inputing the numbers from the domain into the function


so normally the domain is all real numbers
you must exclude number from the domain that make mathematical  undifined impossible stuff exg dividing by zero so
not sure about the ranges so I will leave that out


a. denomenator is x-2
cannot be zero
x-2=0
add 2
x=2

domain: all real numbers except for 2




b. x+2=deomenator
x+2=0
subtract 2
x=-2
x acannot be -2

domain: all real numbers except for -2

c
x cannot be 0
domain: all real numbers except for 0


d. x cannot be -1
domain: all real numbers except for -1


e: x cannot be a negative number or 0
domain: all real numbers greater than zero


f: x cannnot be -2
domain: al real numbers except -2

g: x cannot be 0
domain: all real number except 0

h: x cannot be zero
domain: all real numbers except 0

i: x cannot be 1
doman: all real number except 1

j: 5x-2=0
add 2
5x=2
divide 5
x=2/5

x cannot be 2/5
domain: all real numbers except for 2/5
