Answer:
$2.50
Step-by-step explanation:
Let's take a look at the 4 orders and check the price per pup cake in each order:
Order 1: $5 for 2 cakes, so $2.50 per cake.
Order 2: $7.50 for 3 cakes, so $2.50 per cake.
Order 3: $12.50 for 5 cakes, so $2.50 per cake.
Order 4: $20.00 for 8 cakes, so $2.50 per cake.
Jake has a very consistent pricing of his cakes... they're always $2.50 each.
That price is the relation between the price asked and the number of cakes sold, that's the constant of proportionality in this case.
Answer:
nein
Step-by-step explanation:
We are given linear equation y=−0.7x−28.
We need to find the coordinates of its intersection with the x- and y-axes.
<em>Note: The coordinate at which line intersect x-axis is called x-intercept and The coordinate at which line intersect y-axis is called y-intercept.</em>
In order to find y-intercept, we need to plug x=0 and solve for y.
Plugging x=0
y= −0.7(0)−28 = 0-28 = -28.
<h3>Therefore, the coordinate where line intersect y-axis is (0,-28).</h3>
In order to find x-intercept, we need to plug y=0 and solve for x.
Plugging y=0
0 = −0.7x−28
Adding 28 on both sides, we get
0+28 = −0.7x−28+28
28 = -0.7x
Dividing both sides by -0.7, we get
x=40.
<h3>Therefore, the coordinate where line intersect x-axis is (40,0).</h3>
Answer:
$7.99 each
Step-by-step explanation:
Divide the package price by the package units to get your answer.
(23.97 / 3 = 7.99)

SEQUENCE: 6, 18, 54, 162
18/6 = 3
54/18 = 3
162/54 = 3
then, r (common ratio) = 3

RECURSIVE RULE: r = 3
an = a(n - 1) × r [formula]
ANSWER: an = a(n - 1) × 3
_________________________________________
ITERIATIVE RULE: r = 3, a1 = 6
an = a1 × r^(n - 1) [formula] [ ^(n-1) is an exponent]
ANSWER: an = 6 × 3^(n - 1)
