Answer:
If it is number 5. the answer is 13
Step-by-step explanation:
take the largest number and subtract the smallest number.
You posted a lot of questions. I'll do the first four problems to get you started.
============================
Problem 1
This sequence is arithmetic because we add the same amount (4) each time to get the next term. The first term is -2. The first five terms are: -2, 2, 6, 10, 14
============================
Problem 2
This sequence is geometric. We multiply each term by 1/4 to get the next term. We start with 8 as the first term. The first five terms are 8, 2, 1/2, 1/8, 1/32.
============================
Problem 3
Similar to problem 1. This time we're adding -19 to each term to get the next one. The starting term is -6. This sequence is arithmetic and the first five terms are -6, -25, -44, -63, -82
============================
Problem 4
Similar to problem 2. This sequence is geometric with common ratio 2/3. First term is 6. The first five terms are 6, 4, 8/3, 16/9, 32/27
Answer:
(x+4)(x+5)
Step-by-step explanation:
Before we figure out the problem, we must know that the two numbers in the expression must equal the middle number when added and that when multiplied they must equal the last number.
To do this, we list the multiplies of 9 and 20.
9: 1,9,3
20:1,20,2,10,4,5
From there, you go through both lists and follow the given rules stated at the top. When you do that you get, <u><em>(x+4)(x+5)</em></u>.
To check this answer, you can do a various amount of proofs but the most effective one to me is the F.O.I.L. (first, inner, outer, last) and voila.
Answer:
Equation: y=$3(x)+$30
Total cost $42
Step-by-step explanation:
Calculation to Find the total cost of 4 hours at the aquarium using this formula
y=mx+b
Where,
y intercept=Total cost
m=$3 per hour
b=$30 Tickets
x=4 hours
Let plug in the formula
First step is to form the equation
y=$3(x)+$30
Second step is to substitute 4 hours for m and b
y=$3(4)+$30
Hence:
y=$12+$30
y=$42
Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42
