I need help on 25. I know the answer is 2a but I need to see the work. Please help I’ve tried so many possibilities.

a(2a-3(1-a))+5(a-a^2)

distribute the inner most parenthesis

a( 2a -3+3a))+5(a-a^2)

combine like terms

a(5a-3) +5(a-a^2)

distribute both sets of parenthesis

5a^2 -3a +5a-5a^2

combine like terms

5a^2-5a^2 -3a+5a

What is the equation of the line that is perpendicular to the given line and passes through point (2,5)?

ad-work [718]

Answer:

$\large\boxed{y=-\dfrac{1}{3}x+1}$

Step-by-step explanation:

$\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-slope\\b-y-intercept\to(0,\ b)$

$\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2,\ \text{then}\\\\l\ \parallel\ k\iff m_1=m_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\=======================\\\\\text{We must find the slope of the given line.}\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{Substitute the coordinates of the given points from the graph (0, 1) and (-3, 2)}\\\\m_1=\dfrac{2-1}{-3-0}=\dfrac{1}{-3}=-\dfrac{1}{3}$

$\text{We have an equation:}\\\\y=-\dfrac{1}{3}x+b\\\\\text{From the coordinates of the point (0, 1) we have the y-intercept:}\ b=1.\\\\\text{Therefore we have the equation:}\\\\y=-\dfrac{1}{3}x+1$
