Answer:

x = 8

Step-by-step explanation:

Add $\frac{1}{3}x$ to both sides.

x + 1 = 9

Subtract one on both sides.

x = 8

Find the real and/or imaginary solutions by factoring

SIZIF [17.4K]

Answer:

Step-by-step explanation:

1) (x-3),(x-8)

2) 3x^3+3x^2=27x

3 ( x 3^3+ x ^2 − 9 x − 9 )

3 ( x ^2 ( x + 1 ) − 9 ( x + 1 ) )

3 ( ( x + 1)( x ^2 − 9 ) )

3 ( ( x + 1 ) ( x ^2 − 3 ^2 ) )

3 ( x + 1 ) ( x + 3 ) ( x − 3 )

What is an equation of a parabola with the given vertex and focus? vertex: (5, 4) ; focus: (8, 4)

artcher [175]

The parabola is opens upward.

a = (8 – 5)

= 3

Using the standard form:

(x – h)^2 = 4a(y – k)

(x -5)^2 = 12( y – 4)

In general form

x^2 -10x +25 =12y – 48

x^2 -10x -12y + 73 =0

. Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain

Anettt [7]

Answer:

1. $x-3=-15$
2. $2x=-24$
3. $2x-3=-27$

Step-by-step explanation:

Given the following question:

$2x+9=-15$

To find three equations that have the same solution as the given equation we have to first solve the equation.

$2x+9=-15$
$9-9=0$
$-15-9=-24$
$2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

Equation one:
$x-3=-15$
$-3+3=0$
$-15+3=-12$
$x=-12$

Equation two:
 $2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

Equation three:
$2x-3=-27$
$-3+3=0$
$-27+3=-24$
$-24\div2=-12$
$x=-12$

Hope this helps.
