The two ys must be the same. Equate the two right hand sides.
-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4
Now solve for y
y = x + 2
y = 4 + 2
y = 6
Use the other equation to check it.
y = - x + 10
y = -4 + 10
y = 6
Answer:
It is the 35% percent of 365 miles.
Step-by-step explanation:
Use formula,
35%*x=127 3/4
Step-by-step explanation:
The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
Answer:
(1,40) equation: y=40x
(2,50) equation: y=25x
(4,70) equation: y=17.5x
(7,80) equation: y=11.43x
does not represent a proportional relationship because they all have different equations.
