Answer:

(-6, -5)

Step-by-step explanation:

If you go left 9 times from 2, it goes to -6. Ex: 2, 1, 0, -1, -2, -3, -4, -5, -6. The same goes for 3 units up from -8.

nordsb [41]

Answer:

(y+1)/5

Step-by-step explanation:

you meant f^-1(x) ?

let y= 5x-1

Make x subject of formula

x=(y+1)/5

f^-1(x)=(x+1)/5 replace y by x

Simplify.

irina1246 [14]

We have,
(2y)^3 × y^-1

Simplify the term (2y)^3

= 8y^3 × y^-1

Now, multiply the terms with the same base y by adding their exponents.

Note: Using exponent product rule x^y × x^z = x^(y+z)

= 8y^{3+(-1)}
= 8y^(3-1)
= 8y^(3-1)
= 8y^2

5(x+6)+11=25-3x what is the answer?

Zolol [24]

This is how I did it:
$5(x + 6) + 11 = 25 - 3x$ use distribution
$5x + 30 + 11 = 25 - 3x$ use addition
$5x + 41 = 25 - 3x$ use addition and subtraction
$8x = -16$ use division
$x = -16/8$
$x = -2$

So your answer is $x = -2$
