Yes. Use pythagorean theorem to find that: 9^2 + 12^2 =225 and 15^2 =225.
Answer:
It is most probably 160 cause' it is given in the scale that 1 cm=40 km<em>.</em><em> </em>So as of my view<em>,</em><em> </em><em>there</em><em> </em><em>is</em><em> </em><em>4</em><em> </em><em>cm</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>distance</em><em> </em><em>marked</em><em>.</em><em> </em><em>So</em><em> </em><em>it</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>4</em><em>0</em><em>*</em><em>4</em><em> </em><em>cm</em><em>=</em><em>1</em><em>6</em><em>0</em><em> </em><em>cm</em><em>.</em>
Z=-(b+17/9+4) if that help you
Answer:
x = -5.85
Step-by-step explanation:
Solve the equation
1) ![-\frac{2}{9} x + 2.7 = 4](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B9%7D%20x%20%2B%202.7%20%3D%204)
Subtract -2.7 on both sides by doing the inverse operation.
2) ![-\frac{2}{9}x = 1.3\\](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B9%7Dx%20%3D%201.3%5C%5C)
Multiply both sides by -9/2 to cancel out -2/9x, so that you can isolate "x" by itself.
3)![x = -5.85](https://tex.z-dn.net/?f=x%20%3D%20-5.85)
Answer:
False
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= - ![\frac{1}{m}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bm%7D)
Given a line with m = ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Then the slope of the line perpendicular to it is
= -
= - ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
