Answer:

y=1 3/5x+-5

Step-by-step explanation:

So the y intercept is where your slope meets the middle, basically the y. So it hit the y on -5. And the rise and run 8/5 rise is 8 and run is 5. 8/5= 1 3/5. in equation it is y=1 3/5x+-5.

(3xy)^2x^4y simplifying an expression

DerKrebs [107]

Answer:

$36x^6y^3$

Step-by-step explanation:

The problem needs application of law of indices

$1. (xy)^m = x^my^m$

This means common power for terms can be applied to each term individually.

$x^a x^b = x^(a+b)\\$

Separate power for the terms having same base can be added together.

_______________________________________________________

we will be using these law of indices in the problem

$(3xy)^2x^4y \\=> 3^2x^2y^2x^4y$

applied the first rule of indices as mentioned above

$3^2x^2y^2x^4y\\=>9*x^(2+4)4y^(2+1)\\=>9*4x^6y^3\\=>36x^6y^3$

applied the second rule of indices as mentioned above

Thus, simplified form of (3xy)^2x^4y is $36x^6y^3$ .

What is 172 over 96.75 simplified?

Katyanochek1 [597]

$\frac{172}{96.75}=172:96.75=172:96\frac{3}{4}=172:\frac{387}{4}=172\cdot\frac{4}{387}=4\cdot\frac{4}{9}=\frac{16}{9}=1\frac{7}{9}$

$\frac{172}{96.75}=\frac{17200}{9675}=\frac{16}{9}=1\frac{7}{9}$

Pls help with #14 and #15!!!Asap 15 points

inna [77]

Answer:

14. -g + 10, 15. 12k + 3

Step-by-step explanation:

I'm assuming you want to simplify the equation. For 14, we distribute -2. This gets us -2g + 10 + g. We can simplify that to -g + 10. We can't simplify that, so our answer is complete. For 15, we combine 8k and 4k to get 12k + 3. That can't be simplified, so we are done.
