Answer:
y = 11
Step-by-step explanation:
-5x+3y=-6
9x-4y=1
try adding them together and get
9x-5x+3x-4y=1-6
4x-y=-5
multiply the equation by 3
12x-3y=-15
add this euation to -5x+3y=-6 and get
12x-5x+3y-3y=-6-15
7x=-21
divide both sides by 7
x=-3
subsitute x=-3 for x in any equation
9x-4y=1
9(3)-4y=1
27-4y=1
-4y=-26
divide both sides by -4
y=6 and 2/4 or 6.5
x=-3
y=6.5
Answer:
Step-by-step explanation:
The given question is that the volume of a cube depends on the length of its sides.This can be written in function notation as v(s). What is the best interpretation of v(3)=27.
Solution:
According to the question the volume of a cube depends on the length of its sides. According to the statement we will apply the formula of volume of a cube.
V(s)=s³
In this question we have given s=3ft.
So, we will put the value of 's' in the formula.
V(s)=s³
V(3)=3³
Multiply 3 three times to get the answer.
V(3)=3*3*3
V(3)=27 ft³
This means that the cube has a volume of 27ft³ with the length of its sides 3ft....
