For the first one yes because you add essentially 1, but three times so you have 3x's whish is 3x. for problem two you get 8xy because of the common base number. number two is no. for number three. no,because you distribute the negative which woukd make negative x minus 8. number problem 4 yes because distrubute the 4 to the x and 5
Answer:
<h2>y = -9x - 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em> - slope
<em>b</em> - y-intercept (0, b)
We have the slope <em>m = -9</em> and the y-intercept (0, -2) → <em>b = -2</em>.
Substitute:
<em>y = -9x + (-2) = -9x - 2</em>
For slightly greater clarity, write this expression as
sqrt(6x^8y^9) 6x^8y^9
-------------------- This is equivalent to sqrt[ -------------------- ]
sqrt(5x^2y^4) 5x^2y^4
Reduce the quantity inside the square brackets, obtaining:
6*x^6*y^5
sqrt[ ---------------- ]
5
This simplifies as follows: sqrt[ 6/5 ] * [ x^3 * y^(5/2)
which can be simplified even further if you wish.
The answer is 13 ft because 39 times 4 is 156 and 156 divided by 13 is 12
Step-by-step explanation:
It might be easier thinking of "rate of change" as the slope. Since you'll be finding a slope, then, use the formula 
and substitute the values.
