For this case we must multiply the following expression:

$(2x-6) (3x ^ 2-4x-5)$

Applying distributive property we have:

$(2x) (3x ^ 2) - (2x) (4x) - (2x) (5) - (6) (3x ^ 2) + (6) (4x) + (6) (5) =$

By definition of multiplication of powers of the same base, we have to put the same base and add the exponents:

$6x ^ 3-8x ^ 2-10x-18x ^ 2 + 24x + 30 =$

Adding similar terms:

$6x ^ 3-26x ^ 2 + 14x + 30$

Answer:

$6x ^ 3-26x ^ 2 + 14x + 30$

GUYS HELP!! What’s an equation that represents the line on the graph?

kenny6666 [7]

Answer:

Hey Mate...

Step-by-step explanation:

All that the slope-intercept form (the equation to describe linear equations) is, is an equation (y=mx+b) where m (the number that multiples x) is the slope and b (the number that is not multiplying a variable on the right-hand side of the equation) is the y-intercept.

HELP PLEASE! Im struggling

kondaur [170]

Answer:

c. $\dfrac{2}{3}$

Step-by-step explanation:

Let the common ratio be r.

$a_2 = \dfrac{2}{5}$

$a_3 = \dfrac{2}{5}r$

$a_4 = \dfrac{2}{5}r^2$

$a_5 = \dfrac{2}{5}r^3$

We are told that $a_5 = \dfrac{16}{135}$ .

$\dfrac{2}{5}r^3 = \dfrac{16}{135}$

$\dfrac{5}{2} \times \dfrac{2}{5}r^3 = \dfrac{5}{2} \times \dfrac{16}{135}$

$r^3 = \dfrac{8}{27}$

$r = \sqrt[3]{\dfrac{8}{27}}$

$r = \dfrac{2}{3}$

Answer: c. $\dfrac{2}{3}$

Tell weather the two rates form a proportion. help

Sindrei [870]

7/9 = 42/54...when 42/54 reduces, it becomes 7/9...so this is proportional because proportions are nothing but equivalent fractions.

u could also check it this way...
12/21 = 15/24
cross multiply
(21)(15) = (12)(24)
315 = 288.....these do not equal and are therefore, not proportionate

440/4 = 300/3
110 = 100....not equal, so not proportionate

120/5 = 88/4
24 = 22.....not proportionate

66/82 = 99/123
0.804 = 0.804.......these are proportional

68/172 = 43/123
0.395 = 0.349......nope, not proportional
