This function is in slope-intercept form, which uses the following formula:

$y = mx + b$

m is the slope, and b is the y-intercept of the line.

In f(x) = -2x - 1, the slope is 2, and the y-intercept is -1, or (0, -1).

Urgent ;<br>if a^3+b^3=11 and a^3-b^3=5, evaluate a^6-b^6

11111nata11111 [884]

Factorize using the difference of squares identity.

$a^6 - b^6 = \left(a^3\right)^2 - \left(b^3\right)^2 = \left(a^3 - b^3\right) \left(a^3 + b^3\right)$

Then

$a^6 - b^6 = 11 \cdot 5 = \boxed{55}$

I am very confused on this

Alexus [3.1K]

Well first add up all the numbers of marbles (which is 34 in total) and divide it by the number of black marbles.
(which should give you 8/34)
Then simplify the fraction and you should get 4/17

Jerome recently moved to a new city and bought a home. The assessment rate is 51%. The property tax rate is $53.26 per $1000. Wh

mrs_skeptik [129]

Given:
assessment rate = 51%
tax rate = 53.26 per 1,000

53.26 / 1000 = 0.05326
0.05326 x 100% = 5.326%

Effective tax rate = assessment rate * tax rate
ETR = 51% * 5.326%
ETR = 2.72%
