Line b and h because to find radius it half of the diameter of STRAIGHT lines
Answer:
the opposite of -11 eleven greater than zero eleven below zero positive eleven
Step-by-step explanation:
When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.
Example - we have this proportion:
2-x
5-45
And we can change it into fraction:
\frac{2}{5}=\frac{x}{45}
\frac{2*9}{5*9}=\frac{x}{45}
\frac{18}{45}=\frac{x}{45}
18=x
In case of more complex fractions it may come in handy.
Y = -1/2x - 6......u have a slope of -1/2....u have a y int of -6 or (0,-6)
the x int can be found by subbing in 0 for y and solving for x
0 = -1/2x - 6
1/2x = -6
x = -6 * 2
x = -12.....so ur x int is -12 or (-12,0)
so go ahead and plot ur intercepts.....(0,-6) and (-12,0)...well...u cant really plot ur x axis because ur graph is not big enough....so start at (0,-6)...and I know the slope is -1/2....and u would usually start at (-12,0)...but that is not on the graph....so start at (0.-6)....and go up 1 and to the left 2, plot that point....then up 1 and to the left 2...plot that point......u would eventually cross the x axis at (-12,0).
or u could just go to desmos....its a graphing calculator...and see for urself
