Answer:
A. there is exactly one solution. the solution set is {(2, 0)}.
Step-by-step explanation:
3x + 8y = 6
3x - 8y = 6
when we add these 2 equations, we get
6x + 0 = 12
6x = 12
x = 2
now we use one of the original equations to get y :
3×2 + 8y = 6
6 + 8y = 6
8y = 0
y = 0
-29
-5(6) + 1
-30 + 1
-29
hope this helps !
Answer:
3,4,5 forms a right triangle
1,2 ,9 does not form a triangle
Step-by-step explanation:
Three side lengths that will form a triangle
3,4,5
This is a Pythagorean triple. It forms a right triangle
3^2 +4^2 = 5^2
9+16=25
25=25
Three side lengths that will not form a triangle
1,2 9
The sum of the two smaller sides must be greater then the third
1+2 < 9 not greater
They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>
Answer:
Step-by-step explanation:
8x + 12 = 3x + 5x + 12
8x + 12 = 8x + 12
Bringing like terms on one side
8x - 8x = 12 - 12
x = 0
