Answer:
y < 25x , or y = kx { where k < 25 } , or choosing a time saving worker {as fee is in terms of hours}
Step-by-step explanation:
Services cost : y = 25x , where y is the total fee and x is the number of hours worked.
If customer is looking to choose the less expensive cleaning service ; he / she has following options -
- Choosing fee structure where y < 25x
- Choosing y = k x , where k per hour fee is lesser
- Choosing time efficient worker, as fee is in regards hours utilised.
Answer:
I think it's
D. AC/GI = BC/HI
Step-by-step explanation:
Angles that are congruent don't necessarily mean they're similar. But this is what I saw that is associated with similarity with triangles.
AC and GI are corresponding sides and BC and HI are corresponding sides as well so, yeah. D.
I think.
I guess.
I don't know.
I didn't pay attention, tbh. LOL

Answer:
x = 2 + sqrt(5) or x = 2 - sqrt(5)
Step-by-step explanation using the quadratic formula:
Solve for x over the real numbers:
7 (x^2 - 4 x - 1) = 0
Divide both sides by 7:
x^2 - 4 x - 1 = 0
Add 1 to both sides:
x^2 - 4 x = 1
Add 4 to both sides:
x^2 - 4 x + 4 = 5
Write the left hand side as a square:
(x - 2)^2 = 5
Take the square root of both sides:
x - 2 = sqrt(5) or x - 2 = -sqrt(5)
Add 2 to both sides:
x = 2 + sqrt(5) or x - 2 = -sqrt(5)
Add 2 to both sides:
Answer: x = 2 + sqrt(5) or x = 2 - sqrt(5)
