Is the sequence 5, 9, 15, ... an arithmetic sequence? Explain. Type your answer below.

1 answer:

No it is not an arithmetic sequence because there is no common difference.

9-5=4 and 15-9=6

4!=6

So there is no common difference.

In 1993 eggs cost $0.87 a dozen. In 2003 it cost $1.56 a dozen. How much did the eggs appreciate (percent of increase)?

rusak2 [61]

Answer:

190%

Step-by-step explanation:

$1.56 is close to nearly 2x the value of $0.87

You can start by multiplying $0.87 by 2 to get $1.74

Now put $1.56 / $1.74

This gets you 0.89655172

By rounding this, you can get to 0.90

Move the decimal places two spots over to get a percentage = 90%

Since the eggs didn't decrease in value, you can add the 100% from the beginning of the problem.

100+90=190%

Line CD passes through points C(1, 3) and D(4, –3). If the equation of the line is written in slope-intercept form, y = mx + b,

enot [183]

Answer:

b = 5

Step-by-step explanation:

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = C(1, 3) and (x₂, y₂ ) = D(4, - 3)

m = $\frac{-3-3}{4-1}$ = $\frac{-6}{3}$ = - 2, hence

y = - 2x + b ← is the partial equation of the line

To find b substitute either of the 2 points into the partial equation

Using (1, 3), then

3 = - 2 + b ⇒ b = 3 + 2 = 5
