( x -3 )² = y - 4
y = ( x - 3 )² + 4
One solution is located at the vertex: ( 3, 4 ).
y = - x + b
4 = - 3 + b
b = 7
( x - 3 )² = - x + 7 - 4
x² - 6 x + 9 = - x + 3
x² - 5 x + 6 = 0
x² - 2 x - 3 x + 6 = 0
x ( x - 2 ) - 3 ( x - 2 ) = 0
( x - 2 ) ( x - 3 ) = 0
x 1 = 2, x 2 = 3
y 1 = 5, y 2 = 4.
In order for this solution to be reasonable, the 2nd equation must be:
y = - x + 7
Answer:
x =-27
Step-by-step explanation:
X/3= -9
or,X=-9×3(cross multiplication)
or, X=-27
Answer:
It doesn't make sense and their no picture that provides us with clear evidence on how to answer this better then how your explaing
Step-by-step explanation:
I don't know how to know how to answer this lol, because I need a better explination
Answer:
She made She made 100 grams of 45% sugar syrup.
Step-by-step explanation:
Genna added 45 grams of sugar into 55 grams of water.
Total amount she mixes = 45 + 55 = 100 grams.
Percentage of sugar in total mixture (sugar syrup) = 45 grams sugar in 55 grams syrup.
Here, Solute is sugar and Solvent is water.
mass of solute = 45
mass of solute + mass of solvent = 100
Putting values, we get,
Thus, She made She made 100 grams of 45% sugar syrup.
