Hey there! :)
Answer:
y = x - 3.
Step-by-step explanation:
Given:
Slope = 1
Point on line: (8, 5)
Plug these into the formula y = mx + b, where:
m = slope
x = x coordinate of point
y = y coordinate of point
5 = 1(8) + b
5 = 8 + b
Subtract both sides by 8:
5 - 8 = 8 -8 + b
-3 = b
Rewrite the equation:
y = x - 3.
Given:
The sequence is 8, 10, 12.5, 15.625,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
8, 10, 12.5, 15.625,...
Here, the first terms is 8.
The common ratio is 1.25. So, the given sequence is a geometric sequence.
The explicit formula for a geometric sequence is:
Where, a is the first term and r is the common ratio.
The explicit formula for the given geometric sequence is:
Therefore, the correct option is A.
put all numbers on the left
third equation is the answer
multiply by 3
3x-y=0
The answer would be 1.7 because the tenth place is the first one after the decimal and the 6 rounds up to become a 7.
Answer:
$10 per hour
Step-by-step explanation:
As you can see, at (2, 20) the employee earns 20 dollars for 2 hours and at (4, 40) we can see the employee earn $40 per 4 hours. So we can find the slope of these two points to get the answer.
Slope formula y1-y2/x1-x2
so plug it in
40-20/4-2 and we get 20/2 =10
