Answer:

a³ - 5a² + 4a + 5

Step-by-step explanation:

To solve this, remove the parentheses.  If you were subtracting the two phrases, you would distribute the negative sign to the second phrase, but you are adding so you will not have to do this

4a - a³ - 3 + 2a³ - 5a² + 8

a³ - 5a² + 4a + 5

(-3x)²-(3x-2)²-6*(2x-1.5)
Ilya [14]
Without the instructions, I can only assume that you are to "expand the given expression."

Following order of operations rules requires that (3x-2)^2 and -6(2x-1.5) be evaluated first.

(3x-2)^2 = 9x^2 - 12x + 4   and    -6(2x-1.5) = -12x + 9

Then we have 9x^2 - (9x^2 - 12x + 4) -12x + 9

the 9x^2 terms cancel, leaving  us with 12x - 4 - 12x + 9 = 5 (answer)

Christy spent half of her weekly allowance at the movies. To earn more money her
Mekhanik [1.2K]

Answer:

$6

Step-by-step explanation:

she has $8 now

her parents let her earn $5

so you have to take the $5 from the $8

so $8 - $5 = 3

and she had spent half her allowance so you have to double the $3

$3 * 2 = $6

she has a weekly allowance of $6

Given the point and slope, write the equation of the line
Ratling [72]

7)


\bf (\stackrel{x_1}{1}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-4}{6-1}\implies \cfrac{-5}{5}\implies -1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=-1(x-1) \\\\\\ y-4=-x+1\implies y=-x+5


9)


\bf (\stackrel{x_1}{-12}~,~\stackrel{y_1}{14})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-14}{6-(-12)}\implies \cfrac{-15}{6+12}\implies \cfrac{-15}{18}\implies -\cfrac{5}{6}


\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-14=-\cfrac{5}{6}[x-(-12)] \\\\\\ y-14=-\cfrac{5}{6}(x+12)\implies y-14=-\cfrac{5}{6}x-10\implies y=-\cfrac{5}{6}x+4
