Start by plugging both points within each parenthesis into x and y. Do it interchangeably also!
2(1)+5(1)= 7, which means it isn’t going to prove true. Because 7 isn’t greater than 7.
Since both are 1 it is already interchangeable.
2(-1)+5(4)=-2+20, which is 18. This means the solution doesn’t work, because 7 isn’t greater than 18.
2(4)+5(-1)=8+-5, which is 3. This one must work because 7 is greater than 3!
Please vote my answer brainliest! Thanks.
To solve for y get it by it’s self
y=-2x-4
to solve for x get it by it’s self
2x=-y-4
divide by 2
x=-1/2y-2
Answer:
Survace area = 24in
Step-by-step explanation:
I think its 6in x 4in
so like since the green cylinder is 6in i think you multiply it with the purple
(sorry if its wrong)
Answer:
- demand: p = -9/8x +200
- supply: p = 9/4x -43
Step-by-step explanation:
The 2-point form of the equation for a line can be used as a starting place for writing these equations. For dependent variable p and independent variable x, it will be ...
p = (p2 -p1)/(x2 -x1)(x -x1) +p1
a) Two points on the demand curve are (x, p) = (56, 137) and (72, 119). Then the equation is ...
p = (119 -137)/(72 -56)(x -56) +137
p = -18/16(x -56) +137
p = -9/8x +200
__
b) Two points on the supply curve are (x, p) = (80, 137) and (72, 119). Then the equation is ...
p = (119 -137)/(72 -80)(x -80) +137
p = -18/-8(x -80) +137
p = 9/4x -43
Answer: 4 x 4; 16 x 1; 2 x 8
Step-by-step explanation: You could find all the factors of 16 and done it that way. :)
