The question is asking you to find the slope. Slope intercept form is writen:
y = mx + b (m being the slope and b being the y-intercept)
The slope would be 5 and the y-intercept would be 0.
So, your answer would be y = 5x also known as C. y = 5x
Hope I helped! :)
Answer:
80000 square meters
Step-by-step explanation:
perimeter + dividing fence = 800
let a = length
let b = width
let c = length of dividing fence
perimeter = 2*a + 2*b
let's say...
c is the same as the length
2a + 2b + c = 800
2a + 2b + a = 800
3a + 2b = 800
area = length*width
area = a*b
area / b = a
3*(area/b) + 2b = 800
3*(area/b) = 800 - 2b
area/b = (800 - 2b)
area = (800 - 2b)*b
To make the area large, we make the right hand side large.
800b - 2b^2
If you put in terms of x, y it looks like a downward opening parabola, so the max area is at the vertex. Half way between the roots.
y = -2x^2 + 800x
y = -x^2 + 400x
0 = x*(-x + 400)
roots are x= 0 and x = 400
vertex is at x, aka b = 200
area at b=200 is (800 - 400)*200 = 80000
and a is area/b... 80000/400 = 200
Answer: C
Step-by-step explanation:
A monomial is a expression where in it is x to the power of something, and x cannot be a denominator
A line that is parallel to x=0 has to be x=k where k is a constant. In (4,2), x=4. Therefore, the answer is x=4.
(x+40):12=88-78
(x+40):12=10
x+40=10*12
x+40=120
x=120-40
x=80
