oh geez i hate i-ready's
Step-by-step explanation:
A linear function involves two variables which are in their first power form, such as x and y.
A nonlinear function may include two variables, one or more of which are of the 2nd or higher power.
y = x^2 - 2 is NOT a linear function, because of that power (2). Note how all the other choices show x to the 1st power.
Hello from MrBillDoesMath!
Answer:
0
Discussion:
For the quadratic ax^2 + b^x + c, the discriminant is b^2 - 4ac. In our case, the discriminant is
(-20)^2 - 4 (4)(25) =
400 - 4 (100) =
0
(This means the polynomial has a duplicate root. In fact it factors as (2x-5)^2 ).
Thank you,

Answer:
1. 
2. 
Step-by-step explanation:
Given
Variation: inverse Proportion
y = 7, x = 9
Required
- Write an equation connecting y and x
- Find y when x = 21
Given that thee variation is inversely proportional;
This implies that
Convert variation to equation
----------- Equation 1
Where k is the constant of variation
Substitute 7 for y and 9 for x in equation 1
Multiply both sides by 9
Substitute 63 for k in equation 1
Multiply both sides by x
Hence, the equation connecting x and y is
Solving for when x = 21
Substitute 21 for x in the above equation
Divide both sides by 21
Answer:
4
Step-by-step explanation:
There are 2 outcomes for the first flip and 2 outcomes for the second flip
Multiply
2*2 = 4
4(8x + 56) = 20
= 32x + 224 = 20
