Answer: X is a variable.
Step-by-step explanation:
Answer:
-1/2.
Step-by-step explanation:
slope of a line is (y2-y1)/(x2-x1). Plug in points (5-8)/(11-5). That gives -3/6. Reduce the fraction by 2, so -1/2 is the answer.
Answer:
1st term = 14
2nd term = 29
3rd term = 44
Step-by-step explanation:
1st term = 3 x (5x 1) - 1
= 3 x 5 - 1
= 15 - 1 = 14
2nd term = 3 x ( 5 x 2 ) - 1
= 3 x 10 - 1
=30 - 1 = 29
3rd term = 3 x (5 x 3 ) - 1
= 3 x 15 - 1
= 45 - 1 = 44
Answer:
x=32
Step-by-step explanation:
Since all angles in a triangle add up to 180, set 2x+x+2x+20=180. Then solve for x, and you'll get 32. Hope this helped!
Answer:
1: x = -1
2: x = 3
3: x = -3
Step-by-step explanation:
f(x)=<u>x^3+x^2</u>−9x−9
f(x)=x^2<u>(</u>x+1) <u>−9x−9</u>
f(x) = x^2<u>(x+1)</u> - 9<u>(x+1)</u>
f(x)= (x+1)<u>(x^2-9)</u>
f(x) =(x+1)(x-3)(x+3)
