infinetly many because
for example if 5=5 on a graph. both lines would always touch
You would first start by eliminating one of the variables in order to find the other one.
I chose to eliminate Y, so i multiplies the second equation by -2, in order to cancel Y out.
you would then solve for X, the same you would a one step equation. X =4
You then take one of the original equations, plug X in, and solve for y. Y=5
Hope this helps!
Answer:
u = 150
Step-by-step explanation:
Number of vertices:
10
Find the sum of the interior angles:
180(n - 2)
180(10 - 2)
180(8)
1440
To find u:
u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)
u = 1440 - (1290)
u = 150
Answer:
see explanation
Step-by-step explanation:
Sum the 3 consecutive integers and equate to 36
x + x + 2 + x + 4 = 36
3x + 6 = 36 ( subtract 6 from both sides )
3x = 30 ( divide both sides by 3 )
x = 10
The 3 consecutive integers are
10, 10 + 2, 10 + 4, that is
10, 12, 14
