Answer:
irst, solve for two points which solve the equation and plot these points:
First Point: For
x
=
0
f
(

f
(

)
=
−

or
(

)
Second Point: For

)
We can next plot the two points on the coordinate plane:
graph{(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}
Now, we can draw a straight line through the two points to graph the line:
graph{(y + 2x + 3)(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}
Step-by-step explanation:
Answer:
Brian Peters worked for total of 45 hours.
Step-by-step explanation:
Let the total number of hours worked be 'x'.
Now Given:
Hours spent on other projects = 18 hours.
Also Given:
60% of a week's time working on drawings for a new apartment building.
Hours spent on new apartment building = 
We need to find the total hours worked.
Solution:
Now we can say that;
total number of hours worked is equal to sum of Hours spent on new apartment building and Hours spent on other projects.
framing in equation form we get;
Combining like terms we get;
Now Dividing both side by 0.4 we get;
Hence Brian Peters worked for total of 45 hours.
Not to sure what you mean by factored but 3/4=6/8 so the answer would be 11/8
Answer:
1/2 or .5
Step-by-step explanation:
solve for x in the bottom equation
x = 4 - 8y
substitute the equation for x back into the top equation
4(4- 8y) - y = 3y + 7
solve for y
36y = 9
y = 1/4
substitute y back into the equation solving x
x = 4 - 8(1/4)
solve for x
x = 4 - 2
x = 2
xy = 1/4 * 2
xy = 1/2
You have no number values there; the best I can do is tell you that c = 360-a-b-d. Since b and d are the same measure, we can rename d as b, so your equation is c=360-a-2b. But since a and c are the same, rename a as c to get an equation of c=360-c-2b. Now add c to both sides to give you 2c=360-2b and c=180-b. Can't do anything else with no values.
