You cannot "solve for f" here. However, you can find the zeros/roots of f. Set f = to 0. Then, one by one, set each of the factors = to 0 and solve for x:
x+1=0 results in x=-1; x-5=0 results in x=5, and so on.
Thus, the solutions of f(x)=0 are {-1, 5, -3, 4, 8}
We have that
4x²-25y²<span>-8x+50y-121=0
</span><span>Group terms that contain the same variable, and move the constant to the opposite side of the equation
</span>(4x²-8x)+(-25y²+50y)=121
Factor the leading coefficient of each expression
4(x²-2x)-25(y²-2y)=121
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
4(x²-2x+1)²-25(y²-2y+1)²=121+4-25
Rewrite as perfect squares
4(x-1)²-25(y-1)²=100
<span>Divide both sides by the constant term to place the equation in standard form</span>
(4/100)(x-1)²-(25/100)(y-1)²=100/100
(1/25)(x-1)²-(1/4)(y-1)²=1
[(x-1)²]/25-[(y-1)²]/4=1
the answer is
[(x-1)²]/25-[(y-1)²]/4=1
If you mean fraction,
Tom: 2/3
Sam: 1/4
Now we change the denominator.
Tom: 6/12
Sam: 3/12
6/12 + 3/12 = 9/12
9/12 can be simplified, so 3/4 of the pie was eaten.
4/4 - 3/4 = 1/4
The answer is 1/4.
Answer:
x= -5
Step-by-step explanation:
1 cup = 128 grams
X cups = 96 grams
Cross multiply
128X = 1*96
X=96/128 cups = 6/8 = 3/4 cups.
If she has already added 1/2 cups, then she needs to add (3/4-1/2)=1/4 cup more sugar.
Also please remind her to do the calculations before adding ingredients to avoid ruining a recipe.
