Answer:
![x=-2 \ \ \ and \ \ \ y=1](https://tex.z-dn.net/?f=x%3D-2%20%20%5C%20%5C%20%5C%20and%20%5C%20%5C%20%5C%20%20y%3D1)
Step-by-step explanation:
Suppose numbers are <em>x</em> and <em>y</em>
<u>Product of </u><em><u>x</u></em><u> and </u><em><u>y</u></em><u> is </u><em><u>-2</u></em>
<u />![xy=-2](https://tex.z-dn.net/?f=xy%3D-2)
And sum of <em>x</em> and <em>y</em> is <em>-1</em>
![x=-2 \ \ \ and \ \ \ y=1](https://tex.z-dn.net/?f=x%3D-2%20%20%5C%20%5C%20%5C%20and%20%5C%20%5C%20%5C%20%20y%3D1)
Answer:
x= 2 and y = -4
Step-by-step explanation:
8x + 3y = 4 ---------------------------------(1)
-7x + 5y = -34 -----------------------------(2)
Multiply through equation (1) by 5 and multiply through equation(2) by 3
40x + 15y = 20 ----------------------------(3)
-21x + 15y =-102----------------------------(4)
Subtract equation (4) from equation (3)
61x = 122
Divide both-side of the equation by 61
61x/61 = 122/61
(At the left-hand side of the equation 61 will cancel-out 61 leaving us with just x, while at the left-hand side of the equation 122 will be divided by 61)
x = 122/61
x=2
Substitute x= 2 into equation (1)
8x + 3y = 4
8(2) + 3y = 4
16 + 3y = 4
Subtract 16 from both-side of the equation
16-16 + 3y = 4-16
3y = -12
Divide both-side of the equation by 3
3y/3 = -12/3
y = -4
x= 2 and y = -4
Vertical line has no slope. so only look at the x value. x=-4.
Answer: The perimeter of the triangle is 33b - 8
Step-by-step explanation:
Answer:
So, the answer in short is B) (6,1)
Step-by-step explanation:
If you graph the points, then you see that point A is 8 points away from point B on the X-axis. If you take 8 and divide it by 4, you get 2, so that means that the 1/4 way point is 2 points away from point A, giving you 6 as your x-axis point for this new point. B is the only one with 6 as its spot on the x axis, leaving B as the only choice. BTW you're pretty cute ;)
