You find the midpoint, which is just the average of the coordinates of the endpoints, mathematically:
mp=((x2+x1)/2, (y2+y1)/2)
I am not sure if i understand
Answer:
<h2>x = 0</h2><h2>y = - 2</h2>
Step-by-step explanation:
-5x + y = -2………… Equation 1
-3x + 6y = -12 ………… Equation 2
Using substitution
Make y the subject in equation 1 and substitute it into equation 2 and solve for x
That's
y = 5x - 2
We have
- 3x + 6( 5x - 2) = - 12
- 3x + 30x - 12 = - 12
27x = - 12 + 12
27x = 0
Divide both sides by 27
x = 0
Substitute x = 0 into y = 5x - 2
We have
y = 5(0) - 2
y = - 2
So the solutions are
<h3>x = 0 </h3><h3>y = - 2</h3>
Hope this helps you
I saw the image. QRST is a rectangle.
It has 4 right angles or 90° angles. ∠QRS ∠RST ∠STQ ∠TQR
Based on the image: ∠TQS and ∠RQS are complementary angles. This means that the sum of their angles is 90°
∠TQS is 24°. Thus, ∠RQS is 66°
90° - 24° = 66°
∠TQS + ∠RQS = 90°
Let first number = X and 2nd number = Y
Equation 1: 5X + 8Y = -13
Equation 2: 5X + 10Y = -15
Multiply equation 1 by -1 to get: -5X + -8Y = 13
Now add the 2 equations together:
-5X + 5X = 0
-8Y + 10Y = 2Y
13 + -15 = -2
The total of the 2 equations is 2Y = -2
divide both sides by 2 to solve for Y
Y = -2 / 2
Y = -1
Now we know the 2nd number is -1, so replace Y in the 1st equation and solve for X
5X +8(-1) = -13
5x + -8 = -13
Add 8 to both sides:
5x = -5
Divide both sides by 5 to get x
X = -5 / 5
X = -1
Both numbers are -1
To check replace X and Y with -1 and solve:
1st equation: 5(-1) +8(-1) = -5 + -8 = -13 TRUE
2nd equation: 5(-1) +10(-1) = -5 + -10 = -15 TRUE
Both numbers are -1
