9x1x5= & I have to use parentheses

Answers

Answer 1

Answer:

(9 x1) x 5 = 9 x 5 = 45

9 x (1 x 5) = 5 x 9 = 45

So it doesn't matter where the parentheses were suppose to go as you can see I worked it both ways and the answer is the same.

Hope this helps you. :-)

Answer 2

Answer: You can place the parentheses anywhere cause if you do (9x1)5 it will equal 45. And if you do (5x1)9 it will also be 45. So where ever you put it , it will equal the same amount. But, jus in case next time asked your teacher or friends for further help.

What is the equation of the line that passes through the point (3, 0) and is perpendicular to the line 2x – y = 5?

Answers

Answer:

$\large\boxed{y=-(1)/(2)x+(3)/(2)}$

Step-by-step explanation:

$\text{Let}\ k:y=_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\n\nl\ \perp\ k\iff m_1m_2=-1\to m_2=-(1)/(m_1)\n============================\n\n\text{We have}\ 2x-y=5.\n\n\text{Convert to the slope-intercept form y = mx + b:}\n\n2x-y=5\qquad\text{subtract 2x from both sides}\n\n-y=-2x+5\qquad\text{change the signs}\n\ny=2x-5\to m_1=2\n\n\text{Therefore}\ m_2=-(1)/(2).$

$\text{The equation of the searched line:}\ y=-(1)/(2)x+b.\n\n\text{The line passes through }(3,\ 0).\n\n\text{Put the coordinates of the point to the equation.}\ x=3,\ y=0:\n\n0=-(1)/(2)(3)+b\n\n0=-(3)/(2)+b\qquad\text{add}\ (3)/(2) \text{to both sides}\n\nb=(3)/(2)$
