what is the line of symmetry of the parabola y=x2+6×-9

x=6
x=-9
×=-3​

Answers

Answer 1

Answer:

x = - 3

Step-by-step explanation:

given a parabola in standard form y = ax² + bx + c (a ≠ 0 )

then the equation of the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 6x - 9 ← is in standard form

with a = 1, b = 6 , then the equation of the axis of symmetry is

x = - [tex]\frac{6}{2}[/tex] = - 3 , that is x = - 3

[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

Step-by-step explanation:

Given

[tex]Backpack = 18\frac{7}{9}kg[/tex] --- with math book

[tex]Backpack = 14\frac{7}{8}kg[/tex] --- without math book

Required

Determine the weight of her math book

To do this, we simply calculate the difference in the weights given.

Math Book= Backpack(with math book) - Backpack (without math book)

[tex]Math\ Book = 18\frac{7}{9} - 14\frac{7}{8}[/tex]

[tex]Math\ Book = \frac{169}{9} - \frac{119}{8}[/tex]

Take LCM

[tex]Math\ Book = \frac{8 * 169 - 9 * 119}{72}[/tex]

[tex]Math\ Book = \frac{1352 - 1071}{72}[/tex]

[tex]Math\ Book = \frac{281}{72}[/tex]

[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

One factor of a polynomial p(x) is (x + 7).
What is the numerical value of p(-7)?
Dene-
My Progress

Answers

p(x) = (x + 7)
p(-7) = -7 + 7
p(-7) = 0

The required value of function p(x) at x = -7, p(-7) is zero.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
As given that one factor of a polynomial p(x) is (x + 7).,
Since factor x, + 7 also represents one of the zeros of a polynomial function p(x).

So, when one put the value x = -7 in the function, the function gives zero in the outcome.

Thus, the required value of function p(x) at x = -7, p(-7) is zero.

Answers

Answer:

Carlos spent [tex]\frac{5}{16}[/tex] hours in practicing piano

Step-by-step explanation:

Carlos spent hours in doing his maths homework =[tex]1 \frac{1}{4}[/tex]

Carlos spent hours in doing his maths homework = [tex]\frac{5}{4}[/tex]

We are given that He spent 1/4 of his time practicing piano

So, Time spent by Carlos in practicing piano = [tex]\frac{1}{4} \times \frac{5}{4}[/tex]

Time spent by Carlos in practicing piano = [tex]\frac{5}{16}[/tex]

Carlos spent hours in practicing piano =  [tex]\frac{5}{16} hours[/tex]

Hence Carlos spent [tex]\frac{5}{16}[/tex] hours in practicing piano
