Answer:
<h2>x = 60°, y = 50°</h2>
Step-by-step explanation:
We know: the angles measures in a triangle add up to 180°.
<em>(look at the picture)</em>
z + 50 + 60 = 180
z + 110 = 180 <em>subtract 110 from both sides</em>
z = 70°
x + 50 + 70 = 180
x + 120 = 180 <em>subtract 120 from both sides</em>
x = 60°
Angles x, y and z are on one side of a straight line. Therefore they add to 180°.
x + y + z = 180
60 + y + 70 = 180
y + 130 = 180 <em>subtract 130 from both sides</em>
y = 50°
Answer:
it means y
its just another way of saying it
Answer:
18 : 39
Step-by-step explanation:
36 to 78
Divide both sides by 2.
=> 18 : 39
6(x^2-1)(6x-1/6(x+1))
On factoring (x^2-1)=(x+1)(x-1)
= 6(x-1)(x+1)(6x-1/6(x+1))
Cancelling (x+1) from numerator and denominator we get,
= 6(x-1)(6x-1)/6
Cancelling 6 we get,
= (x-1)(6x-1)
If these are the missing choices:
<span>The ordered pair
that is the solution to the system lies in Quadrant I .
The ordered pair that is the solution to the system lies in Quadrant II .
The x-coordinate of the solution is −3 .
The y-coordinate of the solution is 3.

Given:
<span>1st equation: 8x + 6y = 48
2nd equation: 2x - 3y = -6</span>
<span>My solution:</span>
<span>We need to zero out one variable to get the value of the
other. In this case, we need to multiply the 2nd equation by 4 to
zero out variable x.</span>
<span>4(2x – 3y) = 4(-6)</span>
8x – 3y = -24
<span>We then subtract the answer of the 2nd equation
from the 1st equation.</span>
8x + 6y = 48
-(8x -3y = -24)
8x + 6y = 48
<u>-8x + 12y = + 24</u>
<span> 0 + 18y = 72</span>
y = 72 / 18
y = 4
<span>We then substitute y by its value in the 1st
equation to get the value of x.</span>
8x + 6(4) = 48
8x + 24 = 48
8x = 48 – 24
8x = 24
x = 24/8
x = 3
the coordinate point is (3,4).
<span>Of the 6 choices, the following choices are TRUE:</span>
<span>The ordered pair
that is the solution to the system lies in Quadrant I .
The x-coordinate of the solution is 3.
The y-coordinate of the solution is 4. </span>
