Find the slope and reduce p=(-2,-1) q=(6,5)
Delicious77 [7]

Answer:

3/4

Step-by-step explanation:

Given two points , we find the slope using the formula

m = (y2-y1)/(x2-x1)

   = ( 5 - -1)/ ( 6 - -2)

   = (5+1)/( 6+2)

   = 6/8

   = 3/4

What are the first four terms of the sequence modeled by the recursive formula an=an-1+5 when a1=-3?
vodomira [7]

Given sequence: a_n=a_{n-1}+5

a_1= -3..

We need to find first four terms of the sequence.

We already given first term -3.

Let us find second term a_2.

Plugging n=2.

a_2=a_{2-1}+5 = a_1+5= -3+5 = 2.

Now taking n=3.

a_3=a_{3-1}+5 = a_2+5= 2+5 = 7.

Now, n=4.

a_4=a_{4-1}+5 = a_3+5= 7+5 = 12.

We got terms -3, 2, 7 and 12.

<h3>Therefore, correct option is B) –3, 2, 7, 12.</h3>

Given: g(z)=5z+2.1
Olin [163]

Answer/Step-by-step explanation:

Given the function, g(z) = 5z + 2.1, the table can be completed by substituting the given value of z as follows:

Question 2: z = -7

g(-7) = 5(-7) + 2.1

g(-7) = -35 + 2.1

g(-7) = 32.9

Question 3: z = -8

g(-7) = 5(-8) + 2.1

g(-7) = -40 + 2.1

g(-7) = 37.9
