What are the leading coefficient, constant term and degree, if any, of the algebraic expression -7
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the degree of a certain polynomial will be the largest degree of any term.
For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 7x⁵ has the highest exponent of x i.e. 5. Thus, the polynomial has a degree of 5.
We also know that the coefficient of the term with the largest degree of the polynomial is called the leading coefficient of the polynomial.
For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 7x⁵ has the highest degree of 5. Thus, the leading coefficient of the polynomial
will be 7.
We also know that the constant term of a polynomial has the degree zero. i.e. the term which involves no variable.
For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 3 does not have any variable involved in it. Thus, the constant term of the polynomial
will be 3.
Coming back to the question:
Given the expression
-7
As the expression has only 1 constant term i.e. -7 which does not involve any variable, hence the expression -7 has the degree zero.As the expression does not involve any variable, so it does not have any leading coefficient.As the expression contains only 1 term i.e. -7, and the term does not involve any variable. Thus, the expression has the constant term -7.Answer:
leading coefficient: -7
constant term: -7
degree: 0

Need help writing the standard form of the equation
Answers
Explanation:
Start with the slope-point form: (y - y1) = m(x -x1)
With the point (3,5) and slope 5/3 to get:
Y - 5 = 5/3 (x - 3)
Our target form is the standard form: Ax + By = C
Multiplying both sides of our slope-point form by 3 and expanding the left side:
3y - 15 = 5x - 15
Re-arrange into standard form:

Answer:
29.) y = -1.5x - 20
30.) y = 6 - 3x
Step-by-step explanation:
29.) For parallel lines; M1 = M2
put the equation in the form y = mx + c
the equation becomes 2y = 14 - 3x
therefore y = 7 - 1.5x.
For the points, introduce another point; (x,y) and the initial (-6,-11)
(y - - 11) ÷ ( x - - 6) = -1.5
y+11 = -1.5x - 9
y= -1.5x - 20
30.) still following the same procedure, only that M1 × M2 = -1
M1 = 1/3, M2 = -3
(y + 9)/(x - 5) = -3
y + 9 = 15 - 3x
y = 6 - 3x

A paint color requires the ratio of green paint to yellow paint to be 4 : 9. A container of this paint has 36 pints of yellow paint. How many pints of paint are in the container all together? *
Answers
Answer:
16:36
Step-by-step explanation:
If the ratio is 4:9 and yellow paint is 36 that means you have multiple 9 by a number and that number would be 4 to get 36 and you just multiply 4 by 4 which is 16 and your new ratio will be 16:36
Answer:
16
Step-by-step explanation:
If the ratio is 4:9 and there is 36 pints of yellow then it would be 4:9=x:36. 36 divided by 9 is 4 so you would multiply 4 to 4 and get 16.
