Math pretty much has its own language. In an expression, u have to " break it apart " to make each term
one more then the product of a number and 7 decreased by 5...
" product " means multiply.....so the product of a number and 7 would be 7n.
one more then the product....(7n + 1)....." decreased" means subtract....
so ur expression is : (7n + 1) - 5
(7n + 1) - 5....when n = 6
(7(6) + 1) - 5 =
43 - 5 =
38 <==
Answer:
(0, -2)
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis when x = 0. As shown in the graph, when x = 0, y = -2, so your answer is (0, -2).
Answer:
The function is f(x) = x + 2 when x > 4 and
x when x = 4
Step-by-step explanation:
Given - There were 4 people at the starting meeting. If those 4 people told
2 people about the march, and those 2 people told another 2,
To find - How would we write this function?
Proof -
As given, initially , Total number of people = 4
After that, those 4 people told 2 people about the march
This means,
Total people know about the march = 4 + 2 = 6
Now,
Those 2 people told another 2
This means,
Total people know about the march = 6 + 2 = 8
∴ we get
The function is f(x) = x + 2 when x > 4 and
x when x = 4

Answer: A) The product is rational</h3>
Explanation:
The number 4.56 is rational because any terminating decimal can be written as a fraction of two integers. For example, 4.56 = 456/100
The number is the same as where the '5's go on forever. Repeating decimals like this are rational. It turns out that which you can find through trial and error, or apply a bit of algebra. I'll skip showing those steps unless you need me to go over them.
Because both given numbers are rational, multiplying those two rational numbers will lead to another rational number
rational times rational = rational
I'll skip over the proof of this as well unless you need me to show it.
Answer:
(2.1)
Step-by-step explanation:
assuming your period (.) is actually a comma in the U.S. it would be the coordinate (2,1) where x =2 and y =1.
