They give you the slope - 1/5
y=-1/5x+b
Now plug in the two coordinates of x and y to find b
7=-1/5(-5)+b
7=1+b
b=6
So the answer is y=-1/5x+6

the cost of 21 articles is equal to selling price of 18 articles. find the profit or loss percent.
Answers
Answer:
If all the items are sold, the profit percentage is 14.28%.
Step-by-step explanation:
Given that the cost of 21 articles is equal to selling price of 18 articles, to find the profit or loss percent the following calculation must be performed:
21 = 100
21 - 18 = X
21 = 100
3 = X
(3 x 100) / 21 = X
300/21 = X
14.28 = X
Therefore, if all the items are sold, the profit percentage is 14.28%.

A news story needs to be shared 1,500,000 times in 5 days to get featured on a talk show. The exponential model y=5⋅7x represents the number of shares, y, a news story receives in x days.
About how many days will it take for a news story to reach 1,500,000 shares?
Answers
Answer:
It will take 8.17 days for a news story to reach 1,500,000 shares.
Step-by-step explanation:
Note: The correct exponential model is as follows:
y = 5⋅7^x ......................................... (1)
Where:
y = 1,500,000
x = ?
Substituting y = 1,500,000 into equation (1), we have:
1,500,000 = 5⋅7^x ........................ (2)
Taking the natural log of both sides of equation (2) and solve for x, we have:
ln1,500,000 = xln5.7
x = ln1,500,000 / ln5.7
x = 14.2209756660724 / 1.7404661748405
x = 8.17241379310345
Approximating to 2 decimall places, we have:
x = 8.17
Therefore, it will take 8.17 days for a news story to reach 1,500,000 shares.

Maya and Zack built the tent below in their backyard how much material did they use to build the tent
Answers
Answer:
[tex]Area = 279ft^2[/tex]
Step-by-step explanation:
Given
See attachment for tent
Required
The material needed
This implies that we calculate the surface area of the tent.
This is calculated as:
Area = 2 * Area of Congruent triangles + 2 * Area of Congruent Rectangles + Area of Base Rectangle
So, we have:
[tex]Area = 2 * \frac{1}{2} * 6 * 8 + 2 * 10.5 * 7 + 10.5 * 8[/tex]
[tex]Area = 48 + 147 + 84[/tex]
[tex]Area = 279ft^2[/tex]

Kelly Slater and Andy Irons are in a surf competition among 10 competitors.
If all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place
2nd? Write your answer as a simplified fraction.
Answers
Answer:
The probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
Step-by-step explanation:
Since Kelly Slater and Andy Irons are in a surf competition among 10 competitors, to determine, if all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place 2nd, the following calculation must be performed:
1/10 x 1/9 = X
0.1 x 0.11 = X
0.01111 = X
1/90 = 0.011111 = X
Therefore, the probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
Help plz ! find the measure of the central angle of an arc with length 5pi units and radius of 4.5 units
Answers
Answer:
Angle of Arc θ = 200°
Step-by-step explanation:
Given:
Length of arc = 5π
Radius of circle = 4.5 unit
Find:
Angle of Arc θ
Computation:
Using length of arc formula
Length of arc = [θ/360][2πr]
Putting value or length of arc and radius in given formula;
5π = [θ/360][(2)π(4.5)]
5π = [θ/360][9π]
5 = [θ/360][9]
5 = [θ/40]
θ = 40 x 5
θ = 200
Angle of Arc θ = 200°

The value of y-intercept of the given function is (0,0).
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, We know that;
When a function intersects the y-axis then the point of intersection is called y-intercept of the function,
Also, for y-intercept x = 0.
That is, if f(x) is the function then its y-intercept is (0, f(0) )
By the given table for x = 0, f(x) = 0
Hence, tWhen a function intersects the y-axis then the point of intersection is called y-intercept of the function,
Also, for y-intercept x = 0.
That is, if f(x) is the function then its y-intercept is (0, f(0) )
By the given table for x = 0, f(x) = 0
Hence, the y-intercept of the given function is (0,0),
Thus, The value of y-intercept of the given function is (0,0).
