174/3=58 miles in one hour 7*58=406 miles
or you and do 7/3*174=406
All of the equations contain -4 in their range.
A) -4 = sqrt(x) - 5
1 = sqrt(x)
x = 1; valid
B) -4 = sqrt(x) + 5
-9 = sqrt(x)
x = 81; valid
C) -4 = sqrt(x + 5)
16 = x + 5
x = 11; valid
D) -4 = sqrt(x - 5)
16 = x - 5
x = 21
I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.
Answer:
associative
combining
commutative
Step-by-step explanation:
1. <em>associative property of addition</em> since the grouping is changed
2. <em>combining like terms</em> since it's the addition of 4 and 6
3. <em>commutative property of addition</em> since it's a change of order
Answer:
B, C, and F
Step-by-step explanation:
y = 1/2x
y = 1/2(4)
y = 2
y = 1/2x
y = 1/2(-2)
y = -1
y = 1/2x
y = 1/2(2)
y = 1
