-6.867
You do 13 divided by 15 the plug in the -6 in the front
1 3/4 oz is mixed with 1 gallon of water. With 5 2/5 gallons of water, since we multiplied the number of gallons by 5 2/5, we multiply the amount of chemical by 5 2/5 as well:
1 3/4 * 5 2/5
Convert to improper fractions:
7/4 * 27/5 (because 1*4+3=7 and 5*5+2=27)
189/20 = 9 9/20 (because 20 goes into 189 9 times with 9 left over)
Can u show me what the parallelogram below was
---------------------------------------------------------------------------------
Define Length and Width
---------------------------------------------------------------------------------
Let the width be x
Width = x
Length = 2x + 5
---------------------------------------------------------------------------------
Form equation and solve for x
---------------------------------------------------------------------------------
x(2x + 5) = 63
2x² + 5x = 63
2x² + 5x - 63 = 0
<span>(x+7)(2x-9) = 0
</span>x = -7 (rejected, length cannot be negative) or 2x - 9 = 0
2x - 9 = 0
2x = 9
x = 9 ÷ 2
x = 4.5 ft
---------------------------------------------------------------------------------
Find Length and Width
---------------------------------------------------------------------------------
Width = x = 4.5 ft
Length = 2x + 5 = 2(4.5) + 5 = 14 ft
---------------------------------------------------------------------------------
Answer: Width = 4.5 ft , Length = 14 ft
---------------------------------------------------------------------------------
Answer:
Step-by-step explanation:
Essentially, begin by flipping the x and y terms:
x = (1 - 2y)^2 + 5
Then, solve for y:
Because we know there is only 1 y-value for any given x-value, the inverse of the given function is also a function.
