The number = 7
(2x-5)4=36
2x-5=9 <----- divide by 4
2x=14 <----- add 5
x=7 <----- divide by 2

What is the equation of the line that is parallel to 3x-5y=7 and passes through the point (-10,8)

Karo-lina-s [1.5K]

Answer: y= 3/5 + 18

Step-by-step explanation: Bruh i legit learned this a hour ago at my tuition, ok so basically simply to slope intercept from ye? so it would be y=-3/5x+7

and then you would use the distance formula and ye distance formula is square root of x sub 2 - x sub 1 squared+ y sub 2 - y sub 1 squared

What is the invers function of f(x)=(n+1)^3?

zimovet [89]

Answer:

$f^{-1}(x)=\sqrt[3]{x}-1$

Step-by-step explanation:

$f(x)=(x+1)^3\\\\y=(x+1)^3\\\\x=(y+1)^3\\\\\sqrt[3]{x}=y+1\\\\y=\sqrt[3]{x}-1\\ \\f^{-1}(x)=\sqrt[3]{x}-1$

Graphing both inverses, they will be symmetrical about the line $y=x$ .

What is the constant of proportionality for m=32•g

lina2011 [118]

Answer:

∴ Constant of Proportionality is 32

Step-by-step explanation:

Here Given;

$m=32\times g$ (equation-1)

$\frac{m}{g}=32$ (equation-2) (divide with 'g' on both side)

We know,

The Constant of Proportionality equation is given;

$y=k\times x$ (equation-3)

Where 'k' is known as Constant of Proportionality.

Comparing equation-1 and equation-3;

$y=m$ and $x=g$

Now equation-2 become;

$k=\frac{y}{x}$

Plug $y=m$ and $x=g$ in above equation;

$\frac{m}{g}=k$ (equation-4)

By comparing equation-2 and equation-4;

$k=32$

So Constant of Proportionality is 32
