Write the equation of the line with slope 5/2 through the point (8, -2) in slope intercept
Answer:
Y = 5/2x - 22
Step-by-step explanation:
The equation of the line with slope 5/2 through the point (8, -2) in slope intercept will be y = (5/2)x – 22.
What is the equation of line?The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
The slope is 5/2, then the equation will be
y = (5/2) x + c
The equation of line passing through (8, -2).
-2 = (5/2)(8) + c
-2 = 20 + c
c = -22
Then the equation will be
y = (5/2)x – 22

You want to buy a new pair of Kickin’ sneakers and you see the following ads: Store A All Sneakers 25% Off! Kickin’ Brand priced at $80 Store B All Sneakers 20% Off! Kickin’ Brand priced at $80 Coupon for Store A Good for an additional 10% off on any sneaker purchase. Coupon for Store B Good for an additional 15% off on any sneaker purchase. Which store would you go to in order to get the best deal on your sneakers? Explain your reasoning.
Answer:
store a
Step-by-step explanation:
Store A: 25% off on $80 is $20, so the sneakers would be $60. Take 10% of $60 to get $6 off. The sneakers at Store A would cost $60 - $6 = $54. Store B: 20% off on $80 is $16, so the sneakers would be $64. Take 15% of $64 to get $9.60 off. The sneakers at Store B would cost $64 - $9.60 = $54.40.
Answer:
Store A
Step-by-step explanation:
Store A: 25% off on $80 is $20, so the sneakers would be $60. Take 10% of $60 to get $6 off. The sneakers at Store A would cost $60 - $6 = $54. Store B: 20% off on $80 is $16, so the sneakers would be $64. Take 15% of $64 to get $9.60 off. The sneakers at Store B would cost $64 - $9.60 = $54.40.

Kelsie works at a concert arena. When the price of a ticket is $30, a concert will be attended by 2,500 people. Each time the price is raised by an increment of $5, there will be 100 fewer people at the concert. Kelsie uses the equation R=(30+5n)(2500−100n)R=\left(30+5n\right)\left(2500-100n\right) R=(30+5n)(2500−100n) to determine R, the total concert revenue in dollars when there have been n $5 increases in ticket price. Which conclusion is valid? The total concert revenue decreases when the price of a ticket is greater than $30. The number of people attending the concert is represented by 2500-100n The number of times the price is raised is represented by 30+5n The cost per concert ticket must be less than $55.
Answer:
B
Step-by-step explanation:
IF A= (10i-16j)m/s, B=(3i+8j)m/s, C=6i+20j)m/s determine a and b Such that aA+bB+C=0
Step-by-step explanation:To determine the values of a and b such that aA + bB + C = 0, we can equate the coefficients of the i and j components separately.
Given:
A = (10i - 16j) m/s
B = (3i + 8j) m/s
C = (6i + 20j) m/s
The equation becomes:
(a * 10i - a * 16j) + (b * 3i + b * 8j) + (6i + 20j) = 0
Now let's equate the i and j components separately:
For the i component:
10a + 3b + 6 = 0
For the j component:
-16a + 8b + 20 = 0
We now have a system of linear equations:
10a + 3b + 6 = 0 -- (1)
-16a + 8b + 20 = 0 -- (2)
We can solve this system of equations to find the values of a and b.
Multiplying equation (1) by 8 and equation (2) by 3, we get:
80a + 24b + 48 = 0 -- (3)
-48a + 24b + 60 = 0 -- (4)
Subtracting equation (4) from equation (3), we eliminate b:
128a - 12 = 0
128a = 12
a = 12/128
a = 3/32
Substituting the value of a in equation (1), we can solve for b:
10(3/32) + 3b + 6 = 0
30/32 + 3b + 6 = 0
3/32 + 3b = -30/32
3b = -30/32 - 3/32
3b = -33/32
b = -33/32 * 1/3
b = -11/32
Therefore, the values of a and b such that aA + bB + C = 0 are:
a = 3/32
b = -11/32

What kind of congruent triangles are the Reebok and Adidas logo? (ASA) (SSS) (SAS)
And how can you tell?
The Reebok and Adidas logos are congruent triangles that exhibit the SSS (Side-Side-Side) congruence criterion.
Congruent triangles are triangles that have the same shape and size. They can be superimposed on each other by a combination of translations, rotations, and reflections. In order to determine the type of congruence between the Reebok and Adidas logos, we need to analyze the corresponding sides and angles of the triangles.
When comparing the Reebok and Adidas logos, we observe that the triangles formed by their respective designs have three pairs of corresponding sides that are equal in length. This indicates the SSS (Side-Side-Side) congruence criterion, which states that if the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent.
In the case of the Reebok and Adidas logos, the SSS criterion applies because the lengths of the corresponding sides of the triangles in both logos are equal. This means that the triangles have the same shape and size, and they can be superimposed on each other.
Therefore, the Reebok and Adidas logos exhibit SSS congruence, indicating that the corresponding sides of their triangles are equal in length, leading to their overall congruence.

You are traveling on I-40 in Tennessee and you are stopped by a state trooper for speeding. In Tennessee, the cost of your ticket is determined by the city and/or county in which the ticket is issued. The city council of the city in which you were stopped used the formula c=1.50s-17.5 where c is the cost of the ticket and s is the speed you were traveling. Show how you used the formula c=1.50s-17.5 to solve both problems.
1) Use the formula c=1.50s-17.5 to determine the cost of your ticket if you were traveling at 75mph.
• The ticket for traveling 75 mph would cost
$ ______ ??
2) Use the formula c=1.50s-17.5 to determine how fast you were traveling if the ticket cost $105.50.
• If the ticket cost $105.50 you were traveling at a speed of _____ mph ??
Answer:
1. 1.50(75) - 17.5
112.5-17.5 = $95
2. $105.50 = 1.50s - 17.5
+17.5 +17.5
$123.00 = 1.50s
$123/1.50 1.50/1.50

You are trying to understand the error surrounding the precipitation estimate that you obtained from one of your rain gages. You have determined that for this gage you have a standard error of 30%. For a precipitation event of 5 inches, what is the probability that the actual event is less than 6.5 inches (please assume a normal distribution) (please also provide the response without a percent sign and in the following numerical format: 00.00)
Answer:
The probability that the actual event is less than 6.5 inches is 0.9999.
Step-by-step explanation:
We are given that you have determined that for this gage you have a standard error of 30%.
For a precipitation event of 5 inches, we have to find the probability that the actual event is less than 6.5 inches.
The z-score probability distribution for the normal distribution is given by;
Z = [tex]\frac{X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = mean precipitation event = 5 inches
standard error = [tex]\frac{\sigma}{\sqrt{n} }[/tex] = 0.30
Now, the probability that the actual event is less than 6.5 inches is given by = P(X < 6.5 inches)
P(X < 6.5 inches) = P( [tex]\frac{X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\frac{6.5-5}{0.30}[/tex] ) = P(Z < 5) = 0.9999
The above probability is calculated by looking at the value of x = 5 but in the z table the last value of x is given as 4.40 so we take the area of that value only which has an area of 0.9999.
