Answer:
- Y=2+√4x+28 -
Step By Step:
Ok so, the original expression is 2(x - 2)² = 8(7 + y).
First you Rewrite the expression as 7 + y = (2/8)*(x-2)² = (1/4)*(x-2)²
So know its; y = (1/4)(x-2)² - 7
To find the inverse, switch x and y, and solve for y.
x = (1/4)(y-2)² - 7
Then you Multiply through by 4
4x = (y-2)² - 28
(y-2)² = 4x + 28
y - 2 = √(4x + 28)
y = 2 +/- √(4x + 28)
The third side is = 4
This is a perfect square. Also, using the Pythagorean theorem you can find the third side
3squared + xsquared = 5 squared
9 + xsquared = 25
xsquared = 16
sqrt of 16 = 4
Answer:
Decimal expansion of 1/5 = 0.2
Since variables x and y are in direct proportion,
Y = 12.5/25 x 40
Y = 0.5 x 40
Y = 20.
Answer:
c=4n+9/ Pedro played 12 games at the carnival.
Step-by-step explanation:
After writing the equation( c= 4n+9) you would place 57 in the c variable and solve for n.
57=4n+9
48=4n
12=n
