Write an equation of the line that passes through (3,7) and is parallel to the line shown.
An equation of the parallel line is y=__.
at first we should find the equation of this line so we should find a in the equation of y = a x + b and we do not care about b as it is parallel so a = ( (4 -(-2)) ÷ 1 -(-2)) = 2 so y = 2 x + b and we put x = 3 and y = 7 the result is 7 = 2×3 + b and b = 7 - 6 = 1 the equation is y = 2x + 1

Triangle EFG has vertices E(–3, 4), F(–5, –1), and G(1, 1). The triangle is translated so that the coordinates of the image are E’(–1, 0), F’(–3, –5), and G’(3, –3).
Which rule was used to translate the image?
T4, –4(x, y)
T–4, –4(x, y)
T2, –4(x, y)
T–2, –4(x, y)
Answer:
C.) T2, -4(x, y)Step-by-step explanation:
did on edge :)
The rule of translation of the triangle EFG is (c) T-2,4(x,y)
How to determine the translation rule?We have:
Pre-image: E(–3, 4), F(–5, –1), and G(1, 1).Image: E’(–1, 0), F’(–3, –5), and G’(3, –3).Taking E and E', we have:
E = (-3, 4)
E' = (-1, 0)
Subtract E from E'.
So, we have:
(x, y) = (-1 + 3, 0 - 4)
Evaluate
(x, y) = (2, -4)
This can be rewritten as:
T-2,4(x,y)
Hence, the rule of translation is (c) T-2,4(x,y)

Eddie compared prices of two auto-rental agencies for the use of a mid-size auto for one week. Right Price Auto charged a flat fee of $386 plus $0.20 per mile driven. EconoCar charged a flat fee of $344 plus $0.35 per mile driven. Which equation is written correctly, for the company he used to determine the distance in miles, m, that would make the total charges of both auto-rental agencies equal. Group of answer choices
Answer:
A. 386 + .20m = 344 + .35m
280 miles
Step-by-step explanation:
A. 386 + .20m = 344 + .35m
B. 344 + .20m = 386 + .35m
C. 344 + 20m = 386 + 35m
D. 386 + 20m = 344 + 35m
Right Price Auto charged a flat fee of $386 plus $0.20 per mile driven.
Right price auto = fixed charge + variable charge
= 386 + .20m
Where m = number of miles
EconoCar charged a flat fee of $344 plus $0.35 per mile driven.
EconoCar = fixed charge + variable charge
= 344 + .35m
Where m = number of miles
Equate the total charges of both auto-rental agencies
Right price auto = EconoCar
386 + .20m = 344 + .35m
Collect like terms
386 - 344 = .35m - .20m
42 = .15m
Divide both sides by .15
m = 42 / .15
= 280
m = 280 miles

Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60
Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60

Step-by-step explanation:
Two cars travel at the same distance. The first car travel at 50 miles per hour and reaches its destination at t hours. The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car how long does it take for the first car to reach its destination
Answer:
The first car reaches its destination in 6 hours.
Step-by-step explanation:
Speed of the first car = 50 miles per hour
Time taken = t hours
Distance travelled = Speed × Time = 50 t
Speed of the second car = 60 miles per hour
Time taken = [tex](t-1)[/tex] hours
Distance travelled = Speed × Time = [tex]60(t-1)[/tex]
As two cars travel the same distance,
[tex]50t=60(t-1)\\50t=60t-60\\60=60t-50t\\60=10t\\t=\frac{60}{10}\\t=6[/tex]
So, the first car reaches its destination in 6 hours.
It would take the first car 6 hours to reach its destination.
Speed is the ratio of distance to time. It is given by:
Speed = distance /time
Since the two cars travel at the same distance, let d represent this distance.
The first car travel at 50 miles per hour and reaches its destination at t hours. Hence:
50 = d / t
d = 50t (1)
The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car. Hence the time = t - 1. Hence:
60 = d / (t - 1)
d = 60(t - 1)
d = 60t - 60 (2)
Equating both equations gives:
50t = 60t - 60
10t = 60
t = 6 hours
Hence it would take the first car 6 hours to reach its destination

8. The total weight of a vase and its packaging is: 4 lb. 7 oz. The vase by itself
weighs 3 lb. 11 oz. What is the weight of the packaging materials?
(a) 8 lb. 2 oz.
(d). 6 oz.
(b) 12 oz.
(e) none of these
(c) 1 lb. 4 oz.
Please show the work
Answer:
E
Step-by-step explanation:
the weight of the packaging materials is 12 oz. There are 16 oz in a pound. If the vase weighs 3 lb 11 oz, it would take 5 more oz to reach the next pound, and there was another 7 oz after that. You would then do 5 + 7, which is 12, so the packaging materials weigh 12 oz.
What compound inequality describes this graph
Answer:
0≥x<4
Step-by-step explanation:
first, let's look at this number line.
there is a closed circle at 0 and an open circle at 4. this means that 0 is included (≤ or ≥) and that 4 is not included (< or >).
these are the endpoints, meaning that in this compound inequality, the numbers next to the symbols are 0 and 4.
x is in the middle of this compound inequality.
0 x 4
now, we have to figure out the symbols in between. i wrote out our choices above for each number. the highlighted portion is greater than or equal to 0 and less than 4, so we can write this compound inequality as the following:
0≥x<4
x is greater than or equal to 0, but less than 4

If Casey deposits $16 into his lunch account each week, how much will be deposited in 5 weeks? If Casey decides to buy lunch for his friend at $3.00 per lunch, how many lunches can he buy his friend?
Answer:
The exact number would be 26.66666667 but it would be 26.
Step-by-step explanation:
Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.
