Answer:
y=x+1
Step-by-step explanation:
1) <u>Find the </u><u>slope</u>
m=-3-4/-4-3
m=-7/-7
m=1
2) <u>Use </u><u>y</u><u>=mx+</u><u>c</u>
<u>by </u><u>using </u><u>the </u><u>point </u><u>(</u><u>3</u><u>,</u><u>4</u><u>)</u>
<u>4</u><u>=</u><u>1</u><u>(</u><u>3</u><u>)</u><u>+</u><u>c</u>
<u>4</u><u>=</u><u>3</u><u>+</u><u>c</u>
<u>c=</u><u>1</u>
3) <u>The </u><u>answer</u>
y=x+1
Answer:
(-1)ⁿ(3)ⁿ/10
Step-by-step explanation:
The first term a = 0.3, the second term, ar = 0.9. The common ratio r = ar/a = 0.9/-0.3 = -3.
From the general term of a geometric series,
U = arⁿ⁻¹
= (0.3)(-3)ⁿ⁻¹
= (3/10)(-3)ⁿ⁻¹
= (-1)ⁿ⁻¹(3)(3)ⁿ⁻¹/10
= (-1)ⁿ(3)ⁿ/10
Answer:
see below
Step-by-step explanation:
some of your answers that you currently have are wrong, I'll note those mistakes below
- when factoring (ie 5x+15) only factor out things that can divide both numbers into a whole number ratio
5x+15 = 5(x+3), not (x+3)(x+5)
ie 
we see that 10x can divide the numerator in a whole number ratio
= 10x(x+2), not (x+2)(x+10)
second mistake: the first binomial expansion is incorrect.
you have the expansion formula right, but you added terms wrong, go look at it again
3. x^2+3x+2/ x^2+5x+6
(x+1)(x+2)/(x+3)(x+2)
(x+1)/(x+3)
4. (x^2+6x+8)/(x^2-16)
(x+4)(x+2)/(x+4)(x-4)
(x+2)/(x-4)
5. we can't simplify that any more, x and y are different variables so therefore we cannot cross out stuff on numerator and denominator
6. (x^4y^6)^2
(x^4y^6)(x^4y^6) = 
remember that (x^a)(x^b) = x^(a+b)
or remember that (x^a)^b = x^ab
