Answer:
the desired equation is
y = (1/2)x - 21/2
Step-by-step explanation:
Looks as tho' you may have typed in an extra 'y' here. I will proceed under the assumption that you meant y = (1/2)x - 4. This line has a slope of 1/2.
Any line parallel to it also has a slope of m = 1/2.
Start by replacing y, x, m and b in y = mx + b with the knowns:
y = mx + b becomes -6 = (1/2)(9) + b.
Clear this of fractions by multiplying all 3 terms by 2:
-12 = 9 + 2b, or:
-21 = 2b. Dividing both sides by 2 results in b = -21/2.
Thus, the desired equation is
y = (1/2)x - 21/2
Answer: “samuel earns $20 for each lawn he mows”
Step-by-step explanation:
Y = 2x - 17, comparing to y = mx + c, slope m = 2.
If perpendicular, the new slope would be -1/2, that is the negative reciprocal of 2.
And passing through (-8 , 1).
using y = mx + c, and x = -8, y = 1, m = -1/2
1 = -1/2*-8 + c
1 = 4 + c
1 - 4 = c
c = -3
y = mx + c, substituting m = -1/2, and c = -3, y = -(1/2)x - 3.
Option C.
Let's start with classifications:
monomial: there's only one term, so not + or -
examples: 
or 
binomial: there are two terms, so only one + or one -
examples: 
or 
trinomial: there are three terms
examples: 
or 
Now the degree of a term is the number of variables multplied on that term.
example: 
is degee three, because
and there are three x's.
example: 
really means 
, so that's degree 2.
Finally, the degree of a polynomial (which is what this is asking for) is the degree of the highest degree term.
example: has a 5th degree term and 1st degree term, so this is a degree 5 polynomial, since that's the greatest.
