Answer:

1. Linear; 2. C = 2.50x + 40  

Step-by-step explanation:

1. Prediction

Yes, it is a linear function, because each additional photo adds the same amount to the cost.

2. Equation

         Let C = the cost of the photo package

         and x = the number of photos

Then 2.50x = the cost of the photos

    And $40 = cost of photo shoot

      Then C = 2.50x + 40

The figure below shows that the graph of your equation is a straight line.

Choose three intervals on the real number line that contain both rational and irrational numbers. Do you think that any given in
Helen [10]

Any real number line ranges from negative infinity to positive infinity. A real number number line consists of all the rational and irrational numbers. Let us take three intervals which contain both the rational and irrational numbers.

First interval:  [3,4]

Since every integer is a rational number, 3 and 4 are both rational. In this interval there occurs the value of π (3.14159..) which is an irrational number.

Second interval :  [0,2]

0 and 2 are integers and hence are rational. In this interval, occurs √2 (1.41421...) is an irrational number.

Third interval : [2,3]

In this interval, Eulers number 'e' lie whose value is (2.718281.. )

Hence we can conclude that, there occurs an irrational number between any two rational number.

Given the arithmetic sequence with the following two
kondor19780726 [428]

Answer:

aₙ = -15 + 10 * (n-1)

Step-by-step explanation:

aₙ = a₁ + (n-1)*d       a₁: first term     d: common difference

a₅  a₁ + 4d =25 .... (1)

a₁₁  a₁ + 10d = 85   ...(2)

(2) - (1)     6d = 60

d = 10

a₁ = -15

Formula: aₙ = -15 + 10 * (n-1)
