Answer:
Line B
Step-by-step explanation:
2x-6<2
+6 +6
2x<8
/ /
2 2
x<4
It's Number Line B. All symbols are supposed to be less than or equal to, just don't have that symbol on my keyboard.
Answer:
q=rs
Step-by-step explanation:
r/q=s
*r
q=rs
Are you sure you want ONLY the coefficient of b? If you expand this, you will have b in 3 of 4 terms.
According to Pascal's Triangle, the coefficients of (a+b)^4 are as follows:
1
1 2 1
1 3 3 1
1 4 6 4 1
So (a+b)^4 would be 1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4
Here, you want (3 + b)^4. Here's what that looks like:
3^4 + 4[3^3*b] + 6[3^2*b^2] + 4[3*b^3] + 1[b^4]
Which coeff did you want?
Well, if both Alexis and Tara mine salt for 40 hours... they'd have mine 1,000 pounds of salt. Is this what you were looking for?
Sin a * cos b + cos a * sin b=sin (a+b)
sin 78 * cos 42 + cos 78* sin 42=sin (78+42)=sin 120=sin(180-120)=
sin 60=√3 / 2
Answer: sin 78 * cos 42 + cos 78* sin 42=<span>√3 / 2</span>
