Write a rule for the linear function in the graph Plz help

Mathematics
1 answer:
Scilla [17]3 years ago
4 0

Answer:

  y = -x +4

Step-by-step explanation:

The y-intercept of the line is at +4, so the only viable choice is the last choice.

___

Each of the equations is shown in slope-intercept form:

  y = mx + b

where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...

  y = (some x-term) +4

If you want to spend more brain power on the problem, you can compute the slope of the line as ...

  m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1

Now, you know for sure the equation of the line is ...

  y = -x +4

X + y = 8<br> 3x - y = 12
Virty [35]

Answer:

x = 5 and y = 3

Step-by-step explanation

y crosses out so you are left with

4x = 20 (divide by 4)

x = 5

plug x into either equation

5 + y = 8 (subtract 5)

y = 3

Round 2.71828 to the hearest thousandth.
Colt1911 [192]

Answer:

2.718

Step-by-step explanation:

The thousandths place is 3 to the right of the decimal (the 8).

Since the next number is 2, the number stays the same and does not round up.

Hope this helps :)

Which of the following represents
stealth61 [152]

Answer:

The correct option is (c).

Step-by-step explanation:

The given number is -0.904.

We need to represent the number in scientific notation.

Any number can be written in scientific notation as follows :

a\times 10^b

Where

a is a real number and b is an integer

We can write it as follows :

-0.904=-9.04\times 10^{-1}

Hence, the correct option is (c).

G(n)=-50-15n(n)=−50−15n, Complete the recursive formula of g(n)
UkoKoshka [18]

Answer:

  g(1) = -65; g(n) = g(n-1) -15

Step-by-step explanation:

Using n = 1, 2, 3, we can find the first three terms of the sequence:

  g(1) = -50 -15 = -65

  g(2) = -50 -15(2) = -80

  g(3) = -50 -15(3) = -95

The first term of the arithmetic sequence is -65, so that is g(1). Each next term is 15 less than the one before, so the recursive formula is ...

  g(n) = g(n-1) -15

The complete recursive function definition requires both parts:

  g(1) = -65

  g(n) = g(n-1) -15
