11 / 1/3
11 * 3/1
33/1
Fraction Form: 33/1
Simplified Form: 33
basically you treat y like a number and not a variable
Answer:
a is 4
b is 2y
c is -10y²+9
discriminant is 4(41y²-36)
Step-by-step explanation:
4x²+2xy-10y²+9=0
rewrite in standard form of a quadratic equation like ax² + bx + c = 0
4x²+2yx-10y²+9=0
basically you treat y like a number and not a variable
a is the number with the x²
right away we know a is 4 because of 4x²
b is the one with x so in this formula b is 2y
c is the number without the x which in this case is -10y²+9
discriminant is
b² - 4ac
(2y)²- (4)(4)(-10y²+9)
4y²-(16)(-10y²+9)
4y²-(16)(-10y²+9)
4y²+160y²-144
164y²-144 =
4(41y²-36)
Answer:
-4 1/4 , -3 , 3.3, 3 1/3, 4 1/4
Step-by-step explanation:
make all fractions decimals
4 1/4 = 4.25
3 1/3 = 3.33333..
-4 1/4 = -4.25
4.25 , -3 , 3.3 , 3.33... , 4.25
