The slope of the line that passes through the pair of point (5, 7), (2, 1) is 2
<em><u>Solution:</u></em>
Given that line that passes through the pair of point (5, 7), (2, 1)
To find: slope of the line
<em><u>The slope of line is given as:</u></em>
For a line passing through two points
and
slope is given as:

Here in this problem,

<em><u>Substituting the values in above formula,</u></em>

Thus the slope of given line is 2
Answer:
ln(5/256)
Step-by-step explanation:
Step 1, do the stuff in parenthesis:
1/5 (2ln5 + 3ln5) - 8ln2 = 1/5 (5ln5) - 8ln2
Step 2, remove parenthesis and simplify:
1/5 (5ln5) - 8ln2 = ln5 - 8ln2
Step 3, use this formula-
8*ln2 = ln2^8 = ln256
-to get:
ln5 - 8ln2 = ln5 - ln256
Step 4, use another formula:
ln(A) - ln(B) = ln(A/B), so the answer is ln(5/256) TADA!
this is the step I hope my answer help you .
He should evaluate the function f(x)=−1/3 x+4 for x=3 , Option D is the correct answer.
<h3>What in Interpolation ?</h3>
Interpolation is when the line of best fit is used to determine the value of a point that is within the range of plotted points.
It is given to find the value at Day 3 which lies in the range of the points used for plotting
The line for best fit is
f(x) = (-1/3)x +4
At x = 3
f(3) = (-1/3) * 3 +4
f(3) = -1+4 = 3
Therefore He should evaluate the function f(x)=−1/3 x+4 for x=3
Option D is the correct answer.

Answer:
Option a. Y=3x
Step-by-step explanation:
Let us use cross multiplication method.
Let the cost of 1 magazine be x.
No. of copies Cost
1)50 $150
2)1 x
50x=150 x 1 equation(1)
x=150/50
x=$3
Now see equation (1),
150=50x
150=50 x 3
Here let us represent the cost as y and no. of copies as x.
Y=3x
Therefore, a. Y=3x is the right answer.
Thank you!
