-2x^2 + 500x - 350
You need to plug in the equations for C(x) and R(x) into the equation P(x)= R(x) - C(x) and solve.
Answer:
Step-by-step explanation:
(x-3)^2 + (y+2)^2 = 7^2
Answer:
y = 3/4x - 3
Step-by-step explanation:
If you write the equation in slope-intercept form, you will need the slope(m) and the y-intercept(b):
y = mx + b
To solve this, you first need to know the slope of the line in the given equation. In order to do this, change it to slope-intercept form for easy analyzation:
-3x + 4y = 4
= 4y = 3x + 4
= y = 3/4x + 1
Now, you know the slope(m) is 3/4, so you have this much of the slope-intercept equation:
y = 3/4x + b
At this point, you need to find the y-intercept. This can be done by plugging in the given point in the equation and solving for b:
using (4, 0) and y = 3/4x + b,
(0) = 3/4(4) + b
0 = 3 + b
b = -3
So, that means that the equation for the line is:
y = 3/4x - 3
Answer:75

i believe so
Answer:
x=8.499
y=0.167
Step-by-step explanation:
the equation says:x^2-9y^2=72....(1)
x+3y=9.......(2)
divide (2) from (1),it becomes:
x-3y=8
making x subject of formula,
x=8+3y....(3)
submitting (3) into (1),it becomes
(8+3y)^2-9y^2=72
64+48y=72
48y=72-64=8
y=8/48=0.167......(4)
submitting (4) into (2),it becomes
x+3(0.167)=9
x+0.501=9
x=9-0.501
x=8.499
