Answer:
a. 146
Step-by-step explanation:
{4*[72-6*(3+2)]}-22
=[4*(72-6*5)]-22
=[4*(72-30)]-22
=(4*42)-22
=168-22
=146
SIMILARITIES
Some similarities are that for linear and non-linear systems of equations, you need the same number of equations as unknowns to solve the system and find the only solution for each variable.
DIFFERENCES
Some differences are
The linear system of equations has degree "1" in each of its variables.
The non-linear system of equations has degree "n" in each of its variables.
where n = 1,2,3, ..., i, ..., n.
Answer:
Step-by-step explanation:
First, what's a polynomial? It's an algebraic expression whose only independent variable is x, and in which all the x powers are either zero or positive and are integers: x^3, x^2, x^1, x^0 (for example).
Looking at possible answer choice A, we immediately reject this because that power of x is in the denominator, representing 2x^(-3). This negative power of x is not allowed. Reject A.
In B, we have the powers x^2, x^1 and x^0. Great. This is a polynomial.
In C, we have x^2 + 1 in the denominator of the final fraction. Reject this because of the final term.
In D, we have x^2 + 2x + √
Answer:
y = 2
Step-by-step explanation:
-7x - 5y = -60
plug in 10 where x is
-7(10) - 5y = -60
multiply -7 and 10
-70 - 5y = -60
add 70 to both sides
-5y = 10
divide both sides by -5
y = -2
