Answer:
x=−4/5 or x=−3
Step-by-step explanation:
Step 1: Factor left side of equation.
(5x+4)(x+3)=0
Step 2: Set factors equal to 0.
5x+4=0 or x+3=0
x=−4/5 or x=−3
Answer:
<u>262,144</u> goes in the blank
Step-by-step explanation:
8^6 = 262,144
4^11 = 4,194,304
4,194,304 + 262,144 = 4,456,448
4,456,448 ÷ 17 = 262,144
Answer:
The correct option is;
Step function
Step-by-step explanation:
The given information are;
The cost of mailing a letter for the first ounce= $0.37
The cost for each additional ounce = $0.23
Therefore, the cost of mailing a letter can be found from the relation;
y = (N-1) × $0.23 + $0.37
The step function can be represented as follows;
f(x) = a[b(x - h)] + k
Where;
(h. k) = The starting points
a = The vertical step separation
b = The horizontal step separation
Therefore, in the question, we have;
a = $0.23
b = 1
h = 1
k = $0.37
Which gives;
f(x) = $0.23 × [1(x - 1)] + $0.37 = $0.23 × (x - 1) + $0.37
f(x) = $0.23 × (x - 1) + $0.37 which is similar to y = (N-1) × $0.23 + $0.37
Therefore the function that models the situation is step function.

=================================================
Explanation:
Let's consider the expression (x-y)^2. It expands out to x^2-2xy+y^2. The terms are:
Each of those terms either has a single variable with an exponent of 2, or has the exponents add to 2. Think of 2xy as 2x^1y^1.
In short, this means that the degree of each monomial term is 2.
----------
Now consider (x-y)^3. It expands out into x^3-3x^2y+3xy^2+y^3.
We have terms that either have a single variable and the exponent is 3, or the exponents add to 3. The degree of each term is 3.
----------
This pattern continues.
In general, for (x-y)^n, where n is any positive whole number, the degree of each term in the expansion is n. If you picked any term, added the exponents, then the exponents will add to n.
