Answer:
14.9 miles
Step-by-step explanation:
If the road was created, the 3 different roads would form a right triangle where the new road would be the hypotenuse and the other 2 roads would be the legs.
We can use the pythagorean theorem to find the length of the hypotenuse, or the new road:
a² + b² = c²
14² + 5² = c²
221 = c²
14.9 = c
= 14.9 miles
I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
Answer:
x= -1/2
Step-by-step explanation:
-3/4x+9/4-5=1/8x-1/8
-3/4x-11/4=1/8x-1/8
x=9/4-11/4
x=-1/2
x = sqrt{y}k
K is the constant of proportionality.
128 = sqrt{16}k
128 = 4k
128/4 = k
32 = k
x = sqrt{y}k
x = sqrt{36}•32
x = 6 • 32
x = 192
Find y when x = 48.
x = sqrt{y}k
48 = sqrt{y}32
48/32 = sqrt{y}
(48/32)^2 = [sqrt{y}]^2
2.25 = y
