Determine the pattern rule for the table and write it - 1

Answers

Answer 1
Answer:

Answer:

The rule is: y = -10x+85

Step-by-step explanation:

The rule is given by:

y = mx+b

Here m is the gradient and b is the y-intercept.

We have to take two pairs of input-output to find the rule

Let the two pairs be:

(x1,y1) = (1,75)

(x2,y2) = (2,65)

Slope is found using the formula:

m = (y_2-y_1)/(x_2-x_1)

Putting the values

m = (65-75)/(2-1)\nm = -10

Putting the value of slope

y = -10x+b

Putting a pair of input-output in the equation (1,75)

75 = -10(1) +b\n75 = -10+b\nb = 75+10\nb = 85

Putting the value of b

y = -10x+85

Hence,

The rule is: y = -10x+85

What X !!!!!!!!!!!!!!!!!! Help me please!!!!

Answers

Answer:

x=135°

Step-by-step explanation:

Accordingtotheproblem,

45° + x = 180° [Linearpair]

=> x = 180° - 45°

=> x = 135° (Ans)

Answer:

The value of x is 135°.

Step-by-step explanation:

This figure displays a straight angle, meaning that its measure is 180°.

180° - 45° = 135°

Since angle x is indeed an obtuse angle, the answer is correct! Hope this helps; have a great day.

A DVD store charges $4.70 for each day, a DVD is rented. The store also gives you a dollar off if the DVD is returned before 5 days. a.Write a rule to represent the rental charges. b. How much will you pay if you return the DVD after 4 days? 7 days?

Answers

Answer:

For four days it would be $19.8. For seven days it would be $24.9

Step-by-step explanation:

4 days:

$4.70 x 4 + 1= 19.8

7 days:

$4.70 x 7 = $24.9

I took away 1 from the 4 day equation because the question said you get a dollar off if you return the dvd before 5 days.

Hope this helps!
