A: Slope is 3.90
b: it means each person costs 3.90
c and d i don’t understand what they’re trying to get to i’m sorry
60/360*pi*6^2=6pi. (Area of a sector)
1/2*6*6*sin(60)=9root3. (Area of a triangle)
So it must be the top one
Answer: 106
Step-by-step explanation:
53-(-53)
= 53 + 53 [ the product of - and - gives +]
= 106

The expression which represents Sherly's total income is 7e + 13n.
<h3>What is Cost Price?</h3>
The cost price represents the specific value that represents unit price purchased.
Here,
total pair of earrings = e
total pair of necklaces = n
Cost of 1 pair of earring = $ 7
Cost of 1 necklace = $ 13
earning from earring = 7e
earning from necklace = 13n
Total earning = earning from earring + earning from necklace
Total earning = 7e + 13n
Thus, the expression which represents Sherly's total income is 7e + 13n.

Answer:
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula 
. Substitute the x and y values of the given points into the formula and solve:
Thus, the slope is 
.
2) Now, use the point-slope formula 
to write the equation in point-slope form (from there we can convert it to slope-intercept). Substitute values for 
, 
, and 
.
Since represents the slope, substitute for it. Since and represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, the end result will be the same) and substitute its x and y values into the formula as well. (I chose (4,1), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the answer.
