24. Use the intercepts to graph the equation.
romanna [79]

Answer:

See below ~

Step-by-step explanation:

<u>Finding x-intercept</u>

  • Take y = 0
  • 2x - 5(0) = 10
  • 2x = 10
  • x = 5
  • x-intercept is at (5, 0)

<u>Finding y-intercept</u>

  • Take x = 0
  • 2(0) - 5y = 10
  • -5y = 10
  • y = -2
  • y-intercept is at (0, -2)

<u>Graph (with points marked)</u>

An arithmetic sequence has a first term of 6.3 and a second term of 8.8 Which term has a value of 78.8?
slega [8]
First term [ a ] = 6.3

Common difference [ d ] = 8.8 - 6.3 = 2.5 

Using general term formula,

t_{n} = a + (n-1)d

78.8 = 6.3 + (n-1)*2.5

2.5*(n-1) = 72.5 [ Dividing both sides by 2.5 ]

n-1 = 29

n = 30

Hence, 78.8 is the 30th term in the arithmetic series.
