Thanks.
Step-by-step explanation:
-5x-8y=40
This is a linear equation, and its graph is a right line, we only need two points, because by two points only goes trough only a right line:
1) For x=0→ -5(0)-8y=40
0-8y=40
-8y=40
Dividing both sides of the equation by -8:
-8y/(-8)=40/(-8)
y=-5
Point=(x,y)→Point=(0,-5)
2) For y=0→ -5x-8(0)=40
-5x-0=40
-5x=40
Dividing both sides of the equation by -5:
-5x/(-5)=40/(-5)
x=-8
Point=(x,y)→Point=(-8,0)
With these two points (0,-5) and (-8,0) we can draw the right line.
Answer:
y = 2
x = 7
Explanation:
<u>Make the coefficient of "y" in equation 1 same</u>
{ 5x + 3y = 41 } * 2 → 10x + 6y = 82 ........equation 1
→ 3x - 6y = 9 ........equation 2
<u>solving them using linear combination</u>
============
Find y:
Method 1:
Look at the picture.
is greater than 
Method 2:
Find the common denominator:
multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...
multiples of 9: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...
63 = 7 · 9
therefore
Answer:
Right so SAS means side angle side and the alternate angle theory is that any opposite angle is equal and the sides on the shape are parallel and to be honest thats all i know hope it kind of elps
Step-by-step explanation:
Answer:
4√2
Step-by-step explanation:
This is a special right triangle with angle measures 90° 45° 45° and the side lengths for the ones that sees 45° = a and the one that sees 90° = a√2 (hypotenuse)
