hope it helps
Answer:
Since the question says the number is positive,the number is 1
Step-by-step explanation:
x+x²=2
x²+x-2=0
(x+2)(x-1)=0
x=-2 or 1
8 times 9 = 72 is the answer cuz 72 divided by 8 = 9 and 72 divided by 9= 8
Answer:
y= 1.06x
Step-by-step explanation:
We can write an expression for a direct variation equation as
y=kx
K= constant of proportionality
Then, to write direct variation equation that relates x liters to y quarts, we know that k= 1.06 quarts. which is constant, if we substitute we have
y= 1.06x
