$4x-3y=9\\
-3y=-4x+9\\
y=\dfrac{4}{3}x-3\\\\\\
m=\dfrac{4}{3}$

First put the equation into slope-intercept form. 4x -3y=9 -3y=9-4x -y=3-4/3x y=4/3x - 3 From there you can see that the number in front of x is your slope, so 4/3 in this case Hope that helps!!

Answer: is x = -8

this is how i got it ______

6 x - 3 - 11 - 8 x = 2

(simplify both sides and combine like terms)

(6x + -8x ) + ( -3 + -11) = 2

- 2x + -14 = 2

-2x - 14 = 2

( then you add 14 to both sides)

- 2x - 14 = 2

+14 +14

-2x = 16

( then you divide both sides by -2)

-2x / -2 = 16/ -2

x = -8

ta da!! happy to help!

it made it here. this is for the second one.

( first, we subtract 8n from both sides)

13n + 26 = 8n - 29

-8n -8n

5n + 26 = -29

( then we subtract 26 from both sides)

5n + 26 = -29

- 26 -26

5n = - 55

(after that we divide both sides by 5, we do this to make n alone )

5n/ 5 = -55/ 5

n = -11

Answer:

1.05 × 1.05 × 1.05 × 1.05 × 1.05 = 1.2762815625

Step-by-step explanation:

An exponent indicates how many times the base is a factor in the product. That is, 1.05 to the 5th power means ...

1.05⁵ = 1.05 × 1.05 × 1.05 × 1.05 × 1.05

This multiplication expression is evaluated in the usual way.

= 1.1025 × 1.05 × 1.05 × 1.05

= 1.157625 × 1.05 × 1.05

= 1.21550625 × 1.05

= 1.2762815625

All scientific and graphing calculators have a button for computing the power of a number. On my calculator its label is $\displaystyle \boxed{y^x}$ . The particulars of the function of this button can be found in the manual for your calculator.

For on-line calculators, such as the go.ogle calculator, or the Desmos graphing calculator, the caret (^) is used to signify an exponent. (See the input line in the first attachment for an example.)
