<span>The value of y when x=3 when the value of y varies directly with x^2, and y = 150 when x = 5 is 54. Since the value of y varies directly with x2, then: y = k * x^2, where k is constant. When y = 150 and x = 5, the value of constant is: 150 = k * 5^2. 150 = k * 25. k = 150/25. k = 6. Thus, when x = 3, the value of y will be: y = 6 * 3^2. y = 6 * 9. y = 54.</span>
D. (5,-4)
you can eliminate the 5x and -5x because they are opposites
Then you add the two equations together
you get -9y = 36
solve for y and you get -4
plug -4 into one of the original equations
Ex. 5x+3 (-4)=13
Solve for x
you get 5x = 25
then you finish solving and get x=5
Okay well in fraction for it would be 2121/10000 because the last number behind the decimal is in the ten thousandths spot. ANSWER:2121/10000

Answer:
6.9
Step-by-step explanation:
Since you are supposed to decrease the number in the ratio 3:8 or 3/8 you take the small number that is 3 to be the numerator and 8 to be the denominator then multiply it by 18.4.
That is 18.4×3:8= 184/10×3/8=6.9
So to decrease a number you multiply it with the smallest number as the numerator and the big number as the denominator
To increase a number you multiply it with the big number as the numerator and the small number to be the denominator
