Needs to be factored
Answer:
y=-2x+7
Step-by-step explanation:
y-y1=m(x-x1)
y-5=-2(x-1)
y=-2x+2+5
y=-2x+7

Part B: Write an inequality to represent the amount of money charged per lawn, the cost of the lawnmower and the profit.
Answer:
I got 65
Step-by-step explanation:
The profit will be given as:
P=$15x−$225
(where we subtracted the cost of the mower) so that P=$750
x will be the required number of needed lawns.
We need to solve:
$750=$15x−$225
rearranging:
x=$750+$225 / $15 =65 lawns
−8xy2 + 4x4y2 + 3x3
x4y2 + 4x3y5 + 10x4
x6y2 + 4x3y8 + 10x7
Answer:
Option A is the correct option.
Step-by-step explanation:
Polynomials given in the question are
1)
2)
3)
4)
In a standard form of a polynomial term with the highest degree should be written first, then second highest degree term and similarly other terms should be written.
Here 1st polynomial is in the standard form only in which degree of terms are as followed.
1 term degree of term = (5 +2) = 7
2nd term degree of term = (3 +1) = 4
3rd term 10x² degree of term = 2
So the answer is option A.
