Answer:
Step-by-step explanation:
F(x)=x³-27/x²-9
F(x)=(-9)³-27/(-9)²-9
F(x)=-729-27/-81-9
F(x)=-756/-90
F(x)=42/5
Answer:
298-275 = 23 cm thus D) is the answer
Step-by-step explanation:
First Box:
length l = 9.5 cm
width w = 5 cm
height h = 7 cm
diagonal d = 12.8160056 cm
total surface area S_tot = 298 cm2
lateral surface area S_lat = 203 cm2
top surface area S_top = 47.5 cm²
bottom surface area S_bot = 47.5 cm²
volume V = 332.5 cm³
Second Box:
length l = 7.5 cm
width w = 5 cm
height h = 8 cm
diagonal d = 12.0519708 cm
total surface area S_tot = 275 cm²
lateral surface area S_lat = 200 cm²
top surface area S_top = 37.5 cm²
bottom surface area S_bot = 37.5 cm²
volume V = 300 cm³
Answer:
I think that statement is false
Answer:
P=.75n
Step-by-step explanation:
P=(1-discount)n
=(1-.25)n

Answer:
4x − 5y = 2
13x − 8y = 26
Step-by-step explanation:
The equivalent system must have the same solution as the given system of equations:
4x − 5y = 2
3x − y = 8
Here we have that:
y = 3x - 8
4x - 5y = 2
4x - 5(3x - 8) = 2
4x - 15x + 40 = 2
-11x = -38
Now, we have to verify which of these systems have this answer:
4x − 5y = 2
13x − 8y = 4
13x - 8y = 4
4x − 5y = 2
10x + 3y = 15
10x + 3y = 15
4x − 5y = 2
13x − 8y = 26
4x - 5y = 2
13x - 8y = 26
This is the correct answer
So this is the correct answer
4x − 5y = 2
7x + 6y = 10
