Answer:
Your question does not make much sense but that was only because you were missing one variable which was 4.25 which was what you picked up on Saturday. but anyways you just add 7.75 and 4.25 and you'd end up with 12 so she has 12 pints of the blueberries she needs and to find out the remanding you just subtract from the 20.5 but its better to look at it like 20.50 because that's what it is and then you subtract 12 from 20.50 and you are left with 8.50.
Your answer is 8.5
What is 9 squared?
Why?
Why do we call this "Squared"?
What is 5 cubed?
Why?
Why do we call this "Cubed"?
Answer:
The squared root of 9 is 3
Why - Half of 9 is 3
Why do we called this squared - It is the positive solution of the equation x2 = 9. The number 9 is a perfect square.
5 Cubed is equal to 125
Why - The number 125 on prime factorization gives 5 × 5 × 5. On combining the prime factors in groups of 3 gives 5
Why do we call this cubed = The cube of a number is that number times itself times itself. 5 cubed, denoted 53, is equal to 5×5×5, or 125.

The provided equation has no solution because the square of any number cannon is negative.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is:
Find a solution to the given equation
Please refer to the attached picture for the expression.
We have an expression:
[tex]\rm \dfrac{3}{\left(m+3\right)}-\dfrac{3}{\left(m-3\right)}=\dfrac{m^2+9}{\left(m^2-9\right)}[/tex]
3(m - 3) - 3(m + 3) = m² + 9
3m - 9 - 3m - 9 = m² + 9
m² ≠ -27
As the square of any number cannot is negative, so no solution to the provided equation.
Thus, the provided equation has no solution because the square of any number cannon is negative.

Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?
Answer:
[tex]x=1[/tex] ± [tex]i\sqrt{19}[/tex]
Step-by-step explanation:
First off let's state the quadratic formula
Quadratic formula
[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]
[tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]
For this question our quadratic equation is
[tex]x^2+20=2x[/tex]
Now before we can apply the quadratic formula we first have to set the equation equal to zero. We do this my moving everything to one side and setting it equal to zero.
In this case, we simply move the 2x to the other side making it negative and setting the equation equal to zero.
[tex]x^2-2x+20=0[/tex]
From here we plug in the values to the quadratic equation.
Now incase you don't know
[tex]a =[/tex] Coefficient of [tex]x^2[/tex] value
[tex]b=[/tex] Coefficient of [tex]x[/tex] value
[tex]c=[/tex] The Constant
Now plug in values
[tex]a=1[/tex]
[tex]b=-2[/tex]
[tex]c=20[/tex]
To get the values of x using the quadratic formula we have the plug in the values, we also have to both subtract and add the [tex]\sqrt{b^2-4ac}[/tex] to [tex]-b[/tex]
Plug in values into formula
[tex]\frac{2+\sqrt{(-2)^2-4(1)(20)} }{2(1)}[/tex]
[tex]\frac{2+\sqrt{-76} }{2}[/tex]
[tex]\frac{2+\sqrt{-1} *\sqrt{76} }{2}[/tex]
[tex]\frac{2+i *\sqrt{76} }{2}[/tex]
[tex]\frac{2+i *\sqrt{4(19)} }{2}[/tex]
[tex]\frac{2+i *\sqrt{2^2(19)} }{2}[/tex]
[tex]\frac{2+2i \sqrt{19} }{2}[/tex]
[tex]x=1+i\sqrt{19}[/tex]
Now repeat the steps except subtract from -b rather than add to it.
Final Answer
[tex]x=1[/tex] ± [tex]i\sqrt{19}[/tex]

The function is h(t) = 7/4 cos π/3 t + 9/4,
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
As, h(t) = x cos π/3 t +y
when t= 0, h(t) = 4
when t= 3, h(t) = 0.5
So,
x cos π/3 *0 +y=4
x cos π/3 *3 +y=0.5
and, x+ y = 4, -x+ y =0.5
Now,
2y= 4.5
y= 9/4
and, x= 4-9/4= 7/4.
Hence, h(t) = 7/4 cos π/3 t + 9/4

What is Function?The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here, given function;
f(x) = -x² - 4x + 6
1. If we take -1 common from the given function, we get
f(x) = -1 (x² + 4x - 6)
f(x) = -1 (x² + 4x) + 6
Thus, first block contains -1 and second block contains 4.
2. Then we add half of the coefficient of x², (b/2)², inside the bracket and subtract it outside a times, a(b/2)².
f(x) = -1 ( x² + 2. 2x + 2²) +2² + 6
f(x) = -1 ( x² + 4x + 2²) +4 + 6
Thus, first block contains -1, second block contains 4, third block contains 4, and fourth block contains 4.
3. Then we factorize the bracket and simplify outside the bracket;
f(x) = -1 (x + 2)² + 10
Thus, first block contains -1, second block contains 2 and third block contains 10.
