Write an equation whose graph has intercepts at x= -4 and x= 4 and is symmetric with respect to the origin.

1 answer:

7 0

Since the x-intercepts are already given, we can figure out the equation of a line quite easily.
it would be:
(x-4)(x+4)=y
if you want it not in factored form, just distribute the terms. you will get:
x^2-16=y

both are the same thing, just in different forms.
hope this helped!! xx

I need help this question?

Masja [62]

Answer:

Correct answer: F. graph F or x ∈ |-5 ; 5| (including endpoints)

Step-by-step explanation:

Let us first define the absolute value:

| x | = 1. { x with condition x ≥ 0 }

or 2. { - x with condition x < 0 }

This is a linear inequality

1. x ≤ 5 ∧ x ≥ 0 ⇒ 0 ≤ x ≤ 5 or interval x ∈ |0 ; 5| (including endpoints)

2. - x ≤ 5 when we multiply both sides of the equation by -1 we get:

x ≥ -5 ∧ x < 0 ⇒ -5 ≤ x < 0 or interval x ∈ |-5 ; 0) (including -5)

The solution to this linear inequality is the union of these two intervals:

x ∈ |-5 ; 0) ∪ |0 ; 5| ⇒ x ∈ |-5 ; 5| (including endpoints)

x ∈ |-5 ; 5| (including endpoints)

God is with you!!!

-12x + 12 = 4 - 15x + 9

emmainna [20.7K]

Answer:

x = 1/3

Step-by-step explanation:

-12x + 12 = 4 - 15x + 9

Combine like terms

-12x +12 = -15x+13

Add 15x to each side

-12x+12 +15x = -15x+15x+13

3x+12 = 13

Subtract 12 from each side

3x+12-12 = 13-12

3x = 1

Divide by 3

3x/3 = 1/3

x = 1/3

Find the Area of the shaded part.

Westkost [7]

To find the area of the shaded part we have to subtract the rectangle area from the triangle area :

$s = \frac{1}{2} \times (8x + 2)(6x) - (x)(3x + 1) \\$

$s = \frac{1}{2} \times (48 {x}^{2} + 12x) - (3 {x}^{2} + x) \\$

$s = \frac{48}{2} {x}^{2} + \frac{12}{2} x - 3 {x}^{2} - x \\$

$s = 24 {x}^{2} + 6x - 3 {x}^{2} - x$

$s = 24 {x}^{2} - 3 {x}^{2} + 6x - x$

$s = 21 {x}^{2} + 5x$

And we're done

Have a great day ♡
