Answer:
It's discrete and non-linear
Step-by-step explanation:
it is not continuous and linear because it does not form a line going in one direction the entire time
Answer:
2) x = -2
, y = 2
3) no solution exists
Step-by-step explanation:
Solve the following system:
{-2 x - 3 y = -2
y = 2 x + 6
Hint: | Perform a substitution.
Substitute y = 2 x + 6 into the first equation:
{-2 x - 3 (2 x + 6) = -2
y = 2 x + 6
Hint: | Expand the left hand side of the equation -2 x - 3 (2 x + 6) = -2.
-2 x - 3 (2 x + 6) = (-6 x - 18) - 2 x = -8 x - 18:
{-8 x - 18 = -2
y = 2 x + 6
Hint: | Choose an equation and a variable to solve for.
In the first equation, look to solve for x:
{-8 x - 18 = -2
y = 2 x + 6
Hint: | Isolate terms with x to the left hand side.
Add 18 to both sides:
{-8 x = 16
y = 2 x + 6
Hint: | Solve for x.
Divide both sides by -8:
{x = -2
y = 2 x + 6
Hint: | Perform a back substitution.
Substitute x = -2 into the second equation:
Answer: {x = -2
, y = 2
360 tiles because you have to multiply 12x30.
Answer:
3
Step-by-step explanation:
1 1/2 can be rewritten as 3/2, so 3/2*2=3.
Answer:
4Z+16-Z²
Step-by-step explanation:
Given that,
D = Z+6
C = -2 + Z - Z²
We need to find the value of 3D+C.
So,
3D+C = 3(Z + 6)+(-2 + Z - Z²)
= 3Z+18-2+Z-Z²
= 4Z+16-Z²
So, the required expression is 4Z+16-Z².
