Answer:
Well we are adding by 10 for every 1 increase in x. So slope is 10 / 1 = 10. (1. a slope of 10) is an answer.
We want x = 1 to have y = -5 Slope form is y=mx+b. We know m = 10 bec slope is 10. We have the point (1,-5) on the graph so we solve for b by plugging:
-5 = 10(1) + b and this is b = -15. So graph has function y = 10x-15.
b is the y-intercept so (3. a y-intercept at (0,−15)) is an answer.
9x^3-6x^2+3x
Basically with this you just wanna simplify each term one-by-one.
For instance, look at the first term, 27x^4
Imagine 27x^4/3x
3 goes into 27 9 times, and x goes into x^4 4 times (cuz x to the power of 4 is just x times x times x times x)
So you’re left with 9x^3
Answer:
12742π kilometers
Step-by-step explanation:
Circumference = 2πr
Circumference = 2(r)π
r = 6371
Circumference = 12742π

That sounds like a personal problem
2x=3x+1
First, subtract 3x from both sides to get the variable on only one side
-x=1
Now, divide -x by -1 so that it can get rid of the negative sign and so the only thing remaining on the x's side is x.
Your final answer should be: x=-1
