What is the product (9t-4)(-9t<br> -4)

r-ruslan [8.4K]

Hey Tro2,

Lets find the product of your equation together,

The question we are encountering is : What is the product (9t-4)(-9t<span>-4)?

Lets simplify this step by step, shall we.

$\left(9t-4\right)\left(-9t-4\right)$ : Equation

$\mathrm{Distribute\:parentheses\:using}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$ .

Where : $a=9t,\:b=-4,\:c=-9t,\:d=-4$ .

This leads to $9t\left(-9t\right)+9t\left(-4\right)-4\left(-9t\right)-4\left(-4\right)$ .

Now we have to $\mathrm{Apply\:minus-plus\:rules}$ .

</span>Where: $-\left(-a\right)=a,\:\:\:\:+\left(-a\right)=-a$

$-9t\cdot \:9t-9t\cdot \:4+4\cdot \:9t+4\cdot \:4$

$=-81t^2+16$

Find the inverse of y=1/2x+6

Komok [63]

Answer:

$y = 2x - 12$

Step-by-step explanation:

We want to find the inverse of

$y = \frac{1}{2}x + 6$

We interchange x and y.

$x = \frac{1}{2}y + 6$

We need to solve for y, so let us multiply through by 2.

$2x = y + 12$

Subtract 6 from both sides.

$y = 2x - 12$

Therefore the required inverse is

$y = 2x - 12$
