Answer:
1/16 or 0.0625
Step-by-step explanation:
we can take 4 outside the parentheses and we would get 4^(4-7+1)=4^(-2)= 1/(4^2)=1/16=0.0625.
Switch sides
4/5 (x+3)=y+6
Multiply both sides by 5
5*4/5 (x+3) = 5y+5*6
Simplify
4(x+3) = 57+30
Divide both sides by 4
4(x+3)/4 = 5y/4+ 30/4
Simplify
x+3 = 5y+30/4
Subtract 3 from both sides
x+3 - 3 = 5y+30/4 - 3
Simplify
x=5y+30/4 - 3
99
because 0.49 is less than 0.5(0), we round it down.
L= length
W= width
Perimeter= 2L + 2W
substitute the known numbers
34 ft= 2(8 ft) + 2W
34= 16 + 2W
subtract 16 from both sides
18= 2W
divide both sides by 2
9 ft= W
ANSWER: The width is 9 feet.
Hope this helps! :)
We are given the quadratic:

, with a=1, b=-8, c=15.
We know that the x-coordinate of the vertex, which is the point where the line of symmetry passes through is

.
Thus, the x-coordinate of the vertex is

.
Thus, the line of symmetry is x=4.
Answer: <span>B. The line of symmetry should have been 4 instead of –4. </span>
