Please help me with this.​

Answer:

I put 4, 5, & 6 in order in the photos.

7-8-9 are all linear functions which are written in the y=ax+b format, the ones I put in bold are the equations and I listed the values just in case I'm not sure how your teacher makes you write them.

7.

-0.6=a(-3)+b

0.2=a(1)+b

1.4=a(7)+b

a=0.2,b=0

y=0.2x

8.

-10=a(-5)+b

-1=a(-2)+b

17=a(4)+b

b=5, a=3

y=3x+5

9.

8=a(-5)+b

2=a(-2)+b

-18=a(8)+b

b=-2, a=-2

y=-2x-2

The domain and range is negative infinity to infinity.

For a basic subscription, a cable television provider charges an activation fee of $60, plus $125 per month. What linear function represents the total cost of basic cable subscription for t months? What is the total cost for two years of service?

y=125x+60

$310 for 2 months

$3060 for 2 years

Step-by-step explanation:  let x be the number of months

y=125x+60

y=125(2)+60

y=310 dollars for two months

y=125(24)+60

y=3060 dollars for two years

Arrays are dataset that are represented in rows and columns. Rosa's claim is correct.

An array is a linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations.

From the question, we have:

6 rows and 8 columns

The number (n) of elements in the array is: n = Rows × Columns.

So, we have: n = 6 × 8 =48

Express as sum of three numbers, that is n=12+16+20

Express each term as a product, that is n=2 × 6 + 4 × 4 + 4 × 5

The above expression means that, the array can be split to:

An array of 2 by 6

An array of 4 by 4

An array of 5 by 4

Hence, Rosa is correct.

Answer: d bc I can't tell what  is supposed to say.

Answer:

32,000 or 32 thousand

Step-by-step explanation:

When looking at thousands, we must determine if the hundreds place has more than 5 which would be half of a thousand. So... if there would have been 32500, then the answer would have been 33,000 because there were 500.

Since there are only 450, we are going to have to round back to 32,000 since the number isn't large enough.

One-third of the number is at least 5 units from 31. The number is 78.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that one-third of a number is at least 5 units from 31. The unknown number is x.

( 1 / 3 )x + 5 = 31

x + 15 = 31 x 3

x + 15 = 93

x = 93 - 15

x = 78

Therefore, one-third of the number is at least 5 units from 31. The number is 78.

Let c represent the cost in 2003. Then we have the cost in 2004 is ...

  c + 0.10·c = 385

  1.1c = 385

  c = 385/1.1 = 350

The cost in 2003 was $350.

Answer:

f(- 4) = 13

Step-by-step explanation:

We require to find the value of t which makes f(t) = 13

Equating the right sides gives

- 2t + 5 = 13 ( subtract 5 from both sides )

- 2t = 8 ( divide both sides by - 2 )

t = - 4

Then

(f(- 4) = 13
