Step-by-step explanation:

1/3.x+4=x-2

multiplying 3 to both sides

x+12=3x-6

12+6=3x-x

18=2x

x=9

A quadratic function is shown. f(x) = -x^2+7x-12 one factor of this function is (x-4). What is the other factor of the quadratic

Alexus [3.1K]

Answer:

The other term is (x-3)

Step-by-step explanation:

The quadratic function is:

$f(x)=-x^{2}+7x-12$

Factoring this function we will have:

$f(x)=-(x-4)(x-3)$

Therefore, the other term is (x-3).

Answer:

Option A: $-\frac{4}{3}$ is the correct answer.

Step-by-step explanation:

Given that:

Slope of the line = $\frac{3}{4}$

Let,

m be the slope of the line perpendicular to the line with slope $\frac{3}{4}$

We know that,

The product of slopes of two perpendicular lines is equals to -1.

Therefore,

$\frac{3}{4}.m=-1\\$

Multiplying both sides by $\frac{4}{3}$

$\frac{4}{3}*\frac{3}{4}m=-1*\frac{4}{3}\\$

m = $-\frac{4}{3}$

$-\frac{4}{3}$ is the slope of the line perpendicular to the line having slope $\frac{3}{4}$

Hence,

Option A: $-\frac{4}{3}$ is the correct answer.

6x+3(4x-2)=5(2x-8) the answer is -17/4 but can someone explain how to get that answer? plz help lol

Sergeu [11.5K]

Answer:

Step-by-step explanation:

$6x + 3(4x - 2) = 5(2x - 8)$

Expand the terms in the bracket and simplify

That's

$6x + 12x - 6 = 10x - 40 \\ 18x - 6 = 10x - 40$

Using the subtraction property subtract 10x from both sides of the equation

$18x - 10x - 6 = 10x - 10x - 40 \\ 8x - 6 = - 40$

Add 6 to both sides of the equation

$8x + 6 - 6 = - 40 + 6 \\ 8x = - 34$

Divide both sides by 8

$\frac{8x}{8} = - \frac{34}{8}$

Reduce the fraction with 2

We have the final answer as

$x = - \frac{17}{4}$

Hope this helps you
