(7x^3 – 4x^2) + (2x^3 – 4x^2)
Add 2x^3 to 7x^3
(9x^3 - 4x^2) + (-4x^2)
Add -4x^2 to -4x^2. This would be the same as subtracting 4x^2 from -4x^2
Final Answer: 9x^3 - 8x^2
*The answer cannot be broken down anymore. It's in it's simplest form.
Answer:
It's the second on, 4 units up and 8 units to the left
Answer: y =
x - 3
Step-by-step explanation:
Slope-intercept form is in the form of y=<em>m</em>x + <em>b</em> where m is the slope and b is the y-intercept.
We are given the slope, so we will plug this in.
y = <em>m</em>x + <em>b</em>
y = (
)x + <em>b</em>
<em />
Now, we will solve for the y-intercept by plugging in the point they give us.
y = (
)x + <em>b</em>
(-2) = (
)(5) + <em>b</em>
-2 = 1.25 + <em>b</em>
-3
= <em>b</em>
<em />
Lastly, we will plug this variable into the equation we wrote above for our final answer.
y =
x - 3

Answer:
r = 11
Step-by-step explanation:
C = 2πr
69.08 = 2(3.14)r
69.08 = 6.28r
r = 69.08/6.28
r = 11
