Answer:
A, B, C
Step-by-step explanation:
The variables in a polynomial term are non-negative integers.
A: x is to 1/2 power (square root) . . . not a polynomial
B: x is to -2 power . . . not a polynomial
C: x is to -2 power . . . not a polynomial
D: x is to powers of 2 and 1 . . . is a polynomial
(2,-1)(8,4)
slope = (4-(-1) / (8-2) = (4 + 1)/6 = 5/6
y - y1 = m(x - x1)
(8,4)...x1 = 8 and y1 = 4
slope(m) = 5/6
now we sub
y - 4 = 5/6(x - 8) <==point-slope form
y - 4 = 5/6x - 20/3
y = 5/6x - 20/3 + 4
y = 5/6x -20/3 + 12/3
y = 5/6x - 8/3
-5/6x + y = - 8/3...multiply by -6
5x - 6y = 16 <==standard form
In this question , it is given that p represents cost of 1 container of popcorn . Therefore cost of 5 containers of popcorn = 5p and cost of 3 containers of popcorn = 3p .
And g represents cost of 1 container of granola bars. THerefore cost of 4 containers of granola bars = 4g and cost of 6 containers of granola bars = 6g .
According to the given question, the required linear equations are
5p+4g=42.50 , 3p+6g =34.50 .
And these are the the required system of linear equation .
Answer:
20 square units
Step-by-step explanation:
You count how many across the parallelogram is (which is 4) and you count how high it is (which is 5). Then you multiply 5×4* which equals 20 square units.
*The reason you do this is because base×hieght=area
Answer:
no
Step-by-step explanation:
To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.
10(1) - 6 = 10 - 6 = 4 ≠ - 6
- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30
Then (1, 6 ) is not a solution to the system
