Answer:
-18 b^-4= -18/b^4
Step-by-step explanation:
-3b^4(6b^-8)
Combine coefficients
-3*6 = -18
Combine exponents since the bases are the same, x^y * x^z = x^(x+z)
b^4 *b^ -8
b^(4+-8)
b^ -4
Put back together
-18 b^-4
We also know that x^-y = 1/x^y
-18/b^4
Answer:
The ratio is 6:2:1.
Step-by-step explanation:
Let's denote:
Blue counter b
Red counter r
Yellow counter y.
There is given
r=3b (three times more red as blue) [1]
and
b=2y (twice more blue as yellow.) [2]
Now, replacing [2] to [1] gives
3*2y=r
6y=r.
Hence, the ratio is 6:2:1, because r=6y and b=2y.
Answer: 8
Step-by-step explanation:
4 is the base. 8 are the sides
Since the line 3y = 2x+6 can be simplified to
y = 2/3 x + 2, this would lead it to have a y of 6 when it has an x of 6
Using this, it's possible to subtract 6 from the y value to get to 0, and subtract another 4 to get to -4 (while x is six)
In the equation, this would mean just subtracting:
y = 2/3 x - 4 (after subtracting six from other)
- 4
Equation and answer:
y = 2/3 x - 8
To check : Substitute x with 6;
2/3(6) - 8
4 - 8
-4
When X is 6, Y is -4;
