Answer:
(3, 4 )
Step-by-step explanation:
3x - y = 5 → (1)
x + y = 7 → (2)
adding the 2 equations term by term will eliminate y
4x + 0 = 12
4x = 12 ( divide both sides by 4 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
3 + y = 7 ( subtract 3 from both sides )
y = 4
solution is (3, 4 )
Answer:
D=2.82
Step-by-step explanation:
Here we are given with two coordinates and asked to determine the distance between them.
Here we are going to use the distance formula, which is given as under
Where
Replacing these values in the distance formula
Hence the Distance is 2.82 units
Given the circumference formula for a circle, one can easily find the value of the ray 16:(2×3.14)
Knowing that and using the formula for the volume of a circle V= A×h where A is the surface and h the hight, one would be anxious to find out wether
V=3.14×(2.55)^2×10 could be expressed by 204
