I assume first equation is x-y=1. Solve for x in the first one in terms of y so you get x=y-1 so then you plug it in for x to get y-1+2y=8 then solve for y to get y=3 and then plug it into first equation to get x-3=1 and solve for x
Answer
x=4
y=3
Answer:
3x +2=14
subtract 2 from both sides
3x + 2-2=14-2
3x=12
Step 2:Divide both sides by 3.
3x/3 = 12/3
x = 4
Step-by-step explanation:
Midpoint (m) = (x₁ + x₂)/2 , (y₁ + y₂)/2
= (3 - 11)/2, (-5 + 1)/2
= -8/2 , -4/2
= -4 , -2
distance (d) = √[(x₁ - x₂)² + (y₁ - y₂)²
=√ [(-4 - (-2))² + (-2 - 4)²
= √[(-2)² + (-6)²]
= √[4 + 36]
= √40
= 2√10
Answer:
Step-by-step explanation:
A ∪ B = Q (set of rational numbers)
A ∩ B = Z (set of integers)
Answer:
Step-by-step explanation:
A= 1/2 bh
10.98 = 1/2b (3.6)
10.98=b/2 (3.6)
10.98=b (1.8)
10.98/1.8=b
6.1=b
