Answer:
- leading coefficient: 2
- degree: 7
Step-by-step explanation:
The degree of a term with one variable is the exponent of the variable. The degrees of the terms (in the same order) are ...
6, 0, 7, 1
The highest-degree term is 2x^7. Its coefficient is the "leading" coefficient, because it appears first when the polynomial terms are written in decreasing order of their degree:
2x^7 -7x^6 -18x -4
The leading coefficient is 2; the degree is 7.

<em>Additional comment</em>
When a term has more than one variable, its degree is the sum of the exponents of the variables. The term xy, for example, is degree 2.
Let the steaks = X and the salmon = y.
Set up two equations:
15x + 18y = 559.81
19x + 9y = 583.66
Now using the elimination method:
Multiply the second equation by -2, then add the equations together.
(15x+18y=559.81)
−2(19x+9y=583.66)
Becomes:
15x+18y=559.81
−38x−18y=−1167.32
Add these equations to eliminate y:
−23x=−607.51
Divide both sides by -23 to solve for x:
x= -607.51 = -23 = 26.413478
Now you have the cost for a steak.
To solve for the cost of the salmon, replace x with the value in the first equation and solve for y.
15(26.413478) + 18y = 559.91
396.202174 + 18y = 559.81
Subtract 396.202174 from both sides:
18y = 163.607826
Divide both sides by 18:
y = 163.607826 / 18
y = 9.089324
Round both x and Y to the nearest cent:
X (Steaks) =$26.41
Y (Salmon) = $9.09
Answer:
Step-by-step explanation:
From the question, we are informed that 15⋅324=4,860. Thee exact product of 1.5⋅3.24 will be:
= 1 × 5 × 3 × 24
= 360
The answer will therefore be 360
Answer:
5
Step-by-step explanation:
To solve for hypotenuse we use the Pythagorean theorem:
In this theorem:
c= hypotenuse
a = leg
b = leg
Substitute into theorem:
(square root both sides)
Therefore the hypotenuse has a length of 5.
