Answer:
<h2>15</h2>
Step-by-step explanation:
The formula of a slope <em>m </em>:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
From the graph we have the points (0.2, 3) and (0.4, 6).
Substitute:
![m=\dfrac{6-3}{0.4-0.2}=\dfrac{3}{0.2}=\dfrac{3\cdot10}{0.2\cdot10}=\dfrac{30}{2}=15](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B6-3%7D%7B0.4-0.2%7D%3D%5Cdfrac%7B3%7D%7B0.2%7D%3D%5Cdfrac%7B3%5Ccdot10%7D%7B0.2%5Ccdot10%7D%3D%5Cdfrac%7B30%7D%7B2%7D%3D15)
Answer:
1) congruent
2) corresponding angles
3) 3x+21 = 6x-60
4) x =9
Step-by-step explanation:
1) congruent becuase supplementary means that these 2 angles add up to make 180 degrees.
2) the file below
3) we know they are equal because the congruent correspoding angles.
4) 3x+21 = 6x-60
=> 21 = 9x-60
=> 81 = 9x
=> 9 = x
![y=-|x|](https://tex.z-dn.net/?f=y%3D-%7Cx%7C)
The
value of an absolute value parent function deals with vertical stretches or compressions and it's relation with the x-axis.
Changing the
value to its negative counterpart will reflect the graph over the x-axis (as shown in the picture).
Hope this helps.
頑張って!
