Each piece = (4/5) yards
(4/5) yards * 3 feet = 2.4 feet each piece
which equals 2 feet 4.8 inches each
Answer a = 5 and b = 2.
Procedure
Initially means x = 0, then
5 = a*b^0 = a*1 = a, then a = 5
When x = 1, the height is the double of 5, i.e 10 and
10 = a.b^1 = a.b ⇒ b = 10/a = 10/5 = 2
The a = 5 and b = 2, so the equation is y =5(2)^x
Y=-2x-5
You can divide by -2 on both sides of the equal sign getting the answer above.
Y=-sqrt(x)+1
x must be greater than or equal to zero (positive): x>=0
Options Graphs 1 and 2
when x=0→y=-sqrt(0)+1=-0+1→y=1, then the graph must pass through the point (0,1)
Answer: Graph 2
Answer:
x=1.6
Step-by-step explanation:
first follow PEMDAS
so you multiply -2 into the parentheses
-8x and +10
so now it is
5x+3x=-8x+10
add 5x +3x
get 8x
then we have
8x=-8x+10
add -8 to the other side
get 16x
so now 16x=10
divide 16 by 10
get x=1.6
