The complete table of values for the x values in function h(x) is
x | -2 -1 0 1 2
h(x) | 3 2 1 0 -1
How to complete the table of the function h(x)?From the question, the definition of the function is given as
h(x) = 1 - x
Also, from the table of the values;
We have the following x values
x = -2, -1, 0, 1 and 2
The next step is that
We substitute each value of x in the equation h(x) = 1 - x
So, we have
When x = -2
h(-2) = 1 + 2
Evaluate
h(-2) = 3
When x = -1
h(-1) = 1 + 1
Evaluate
h(-1) = 2
When x = 0
h(0) = 1 + 0
Evaluate
h(0) = 1
When x = 1
h(1) = 1 - 1
Evaluate
h(1) = 0
When x = 2
h(2) = 1 - 2

Brand A granola is 25% nuts and dried fruit and brand B granola is 20% nuts and dried fruit. How much of sweet item A and sweet item B should be mixed to form a 10-lb batch of sweetsthat is 22% nuts and dried fruit?The batch of sweets should contain of Brand A granola and of Brand B granola.
Answers
The batch of sweet should contain 4 lb of Brand A granola
The batch of sweet should contain 6 lb of Brand B granola
Explanations:Total amount of sweet items = 10 lb
Let the amount of brand A granola be x
Amount of brand B granola = 10 - x
Amount of nuts and dried fruits in the total sweet items = 22% of 10
Amount of nuts and dried fruits in the total sweet items = 0.22 x 10
Amount of nuts and dried fruits in the total sweet items = 2.2lb
Amount of nuts and dried fruits in brand A granola = 25% of x
Amount of nuts and dried fruits in brand A granola = 0.25x
Amount of nuts and dried fruits in brand B granola = 20% of (10-x)
Amount of nuts and dried fruits in brand B granola = 0.2(10 - x)
Amount of nuts and dried fruits in brand A granola + Amount of nuts and dried fruits in brand B granola = Amount of nuts and dried fruits in the total sweet items
0.25x + 0.2(10 - x) = 2.2
0.25x + 2 - 0.2x = 2.2
Collect like terms
0.25x - 0.2x = 2.2 - 2
0.05x = 0.2
x = 0.2 / 0.05
x = 4 lb
The batch of sweet should contain 4 lb of Brand A granola
Amount of brand B granola = 10 - x
Amount of brand B granola = 10 - 4
Amount of brand B granola = 6 lb
The batch of sweet should contain 6 lb of Brand B granola

Using the Factor Theorem, the polynomial function with the desired characteristics is given by:
f(x) = -x(x² + 9)(x - 1)(x - 2).
Factor TheoremThe Factor Theorem states that a polynomial function with roots(also called zeros) [tex]x_1, x_2, \codts, x_n[/tex] is given by the rule presented as follows.
[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]
In which a is the leading coefficient of the polynomial, determining if it is positive(a positive) or negative(a negative), determining the end behavior of the function.
For this function, we have:
Two complex roots, hence a factor of (x² + 9).A root at x = 0, hence f(x) = ax(x² + 9).The two other roots are free, hence I am going to attribute x = 1 and x = 2, hence the equation is:
f(x) = ax(x² + 9)(x - 1)(x - 2).
The end behavior is that the function increases to the left and decays to the right, meaning that the leading coefficient is negative, hence a possible function is given by:
f(x) = -x(x² + 9)(x - 1)(x - 2).

On the last four holes, he scores 5 over par, 3 under par, 6 over par, and 3 underpar.Part 1 out of 3Enter and find the value of an expression that gives Cameron's score for 4 holes of golf.The expression is? Cameron's score is?Can someone please help?
Answers
Let the numbers over par is (+) and the numbers under par is (-)
he scores 5 over par, 3 under par, 6 over par, and 3 under
par.
so, the expression is : (5) + (-3) + (6) + (-3)
So, the result will be:
over par = 5 + 6 = 11
under par = 3 + 3 = 6
subtract under par from over par
so, 11 - 6 = 5
So, the Cameron's score = 5

so, we can represent this as

Define a variable, used let statements, set up an equation, then solve. Morgan is making two cookie recipes. Recipe A calls for one-third third less than twice the number of cups of sugar that Recipe B calls for. If she needs four and one-sixths cups of sugar in all, how many cups will she need for Recipe A?
Answers
EXPLANATION
Let's see the facts:
-Morgan is making ----------------> 2 cookie recipes.
Recipe A ---> A = 2RecipeB -(1/3) 2RecipeB
-She needs-----------> Recipe A + Recipe B = 4 1/6 cups of sugar
Now, we have a system of equations:
(1) A = 2B -(1/3)2B
(2) A + B = 4 1/6
Multiplying both sides of (1) by 3:
3A = 6B - B
Simplifying:
3A = 5B
Isolating B:
B = 3/5 A
Substituting B-value in (2)
