Solve the equation for x:

1 answer:

8 0

3x - 17 = 9x + 7

Rearrange on same sides
-17 - 7 = 9x - 3x
-24 = 6x

Divide by 6 on either sides to isolate 6
$-\frac{24}{6} = \frac{6x}{6}$
6 and 6 cancels out
-4 = x

Answer is:
B. x = -4

What is the axis of symmetry of the parabola y= 1/3 (x-10)^2 - 6

GalinKa [24]

Answer:

The equation of the axis of symmetry is equal to

$x=10$

Step-by-step explanation:

we have

$y=\frac{1}{3}(x-10)^2-6$

This is the equation of a vertical parabola written in vertex form open upward (because the leading coefficient is positive)

The vertex represent a minimum

The axis of symmetry is equal to the x-coordinate of the vertex

we have that

The vertex is the point (10,-6)

The x-coordinate of the vertex is 10

therefore

The equation of the axis of symmetry is equal to

$x=10$

Shaun is 4 years older than her sister Charmaine. If the sum of their ages is 16, how old is Charmaine?

skad [1K]

Step-by-step explanation:

$let \: the \: age \: of \: charmaine \: be \: x$

$according \: to \: question$

$4 + x = 16$

$x = 16 - 4$

$12$

$so \: the \: age \: of \: shaun \: is \:$

$x + 4$

$12 + 4$

$16$
