Which is the best estimate for the sum 2/9 +10/11? I need this now please helpppppp! Thxx -UrLocalDummy
Answer:
The best estimate is 0+1=0
Step-by-step explanation:
estimate
2/9 < 1/2 and close to 0 so 2 /9 = 0
10/11 < 1 but close to 1 so 10 /11 = 1
so it's 0 + 1 = 1

Hope this helped!The quadratic function f(x) has a vertex at (5,-5) and opens downward.
If g(x) = (x + 5)2 + 5, which statement is true?
A. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = -5.
B. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = -5.
C. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = 5.
D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = 5.
Answer:
The correct answer is A.
Step-by-step explanation:
We're told that f(x) has its vertex at 5, -5 and opens downward. This tells us that it's axis of symmetry is x = 5.
The format of the function g(x) shows us that its axis of symmetry is x = -5. We're shown this because of the (x + 5)² component.
So the correct answer is A.
Using the properties of the quadratic function we can review the different answers, the correct one is
D. The axis of symmetry of f(x) is x = -5,
the axis of symmetry of g(x) is g(x) = 5.
The quadratic function is a quadratic polynomial that has a parabolic form and a general equation
g (x) = a x² + bx + c
where a, b, c are the coefficients, x is the independent variable and g the dependent
If the function has real roots it can be written in vertex form
g (x) = a (x-h) ² + k
where (h, k) are the coordinates of the vertex
The quadratic function has several properties:
The graph of this function opens up if the coefficient "a" is positive and down if it is negative, The axis of symmetry is parallel to the y axis, passing through the vertex of the function The vertex of the parabola corresponds to the maximum or minimum of the curveThe function can be written as a vertex value that cancels the binomial is where the symmetry axis passes
in this case, for the parabola to open downwards, the curve must be:
g (x) = - (x + 5) ² + 5
this is the expression in vertex form, let's find the value that cancels the binomial,
x + 5 = 0
x = -5
at this point where the axis of symmetry passes
The value of the function for this point is
x = -5
g (x0 = - (-5 + 5) ² + 5
g (x) = 5
Using the properties of the quadratic function we can review the different answers, the correct one is
D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is
g(x) = 5

Answer:
y = 8; x = 6 [tex]\frac{7}{8}[/tex] ; n = 1 [tex]\frac{2}{23}[/tex] ; p = 55
Step-by-step explanation:
First proportion
// How to solve it
// firstly, multiply both sides by y, so that y would be in numerator
[tex]\frac{16}{16} * y[/tex] = [tex]\frac{8}{y} * y[/tex]
// now we get
[tex]\frac{16y}{16}[/tex] = 8
// secondly, divide both sides by [tex]\frac{16}{16}[/tex], so that we'd have y on one side and the expression on the other side
y = [tex]\frac{16}{16}*8[/tex]
// since [tex]\frac{16}{16}[/tex] = 1
y = 8
Second proportion
// divide both sides by 22, so that there'd be unknown variable x on one side and the expression on the other side
x = [tex]\frac{10*22}{(y*4)}[/tex]
Is this y from the first proportion?
If so, then x = [tex]\frac{10*22}{(8*4)}[/tex] = [tex]\frac{220}{32}[/tex] = [tex]\frac{55}{8}[/tex] = 6 [tex]\frac{7}{8}[/tex]
Third proportion
// divide both sides by 5
n = [tex]\frac{5}{23} * 5[/tex] = [tex]\frac{25}{23}[/tex] = 1 [tex]\frac{2}{23}[/tex]
Fourth proportion
// divide both sides by 10
p = [tex]\frac{22}{4} *10[/tex] = 55

2x² + 5x - 42 = 0 * PLEASE SHOW YOUR WORK *
Answer:
x = - 6, x² = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0
2x^{2} (x + 6) - 7 (x + 6) = 0
(x + 6) x (2x - 7) = 0
x + 6 = 0
2x - 7 = 0
x = - 6
x = [tex]\frac{7}{2}[/tex]
x = - 6, x² = [tex]\frac{7}{2}[/tex]
6+n/5=9
What is happening to the variable?
How do you solve for the variable?
Answer:
n=15
Step-by-step explanation:
(subtract 6 from both sides of the equation.)
6+n/5=9
6+n/5-6=9-6
(Now you will have to simplify.)
n/5=3
(You will have to multiply all terms by the same value to eliminate fraction denominators.)
n/5=3
5xn/5=5x3
(You will now have to simplify.)
n=15
And that's how you get your answer.
