I had to do this and it’s fake, my whole class got it wrong even though we all put the right answer so ya
Answer: The answer is A:
Step-by-step explanation: Yes, because it has a constant rate of change.
Answer:
-7
Step-by-step explanation:
21 ÷ (4+3) - 10
=> 21 ÷ (7) - 10
=> 3 - 10
=> -7
1) The triangles are similar, so correponding sides have the same ratio.
.. 3x/20 = (4x +2)/28
.. 3x/5 = (4x +2)/7 . . . . . . . multiply by 4
.. 7*3x = 5(4x +2) . . . . . . . multiply by 35 = 5*7
.. 21x = 20x +10 . . . . . . . . eliminate parentheses
.. x = 10 . . . . . . . . . . . . . . . subtract 20x
2) The triangles are similar, so corresponding measures have the same ratio.
.. x/42 = 10/15
.. x = 42*(10/15) = 28
3) The third angle of triangle ABC is 180° -20° -80° = 80°. Then two of the angles of ABC match those of JKL. The 3rd answer selection is appropriate.
Answer: second option
Step-by-step explanation:
The equation of the line in slope-intercept form is:
Where m is the slope and b is the y-intercept.
Rewrite the expression as:
Solve for "y":
You can identify that:
Therefore, the line intersects the y-axis at the point (0,10)
For the graphs of inequalities with 
the line must be solid.
The inequality given is 
and it can be written as 
Then, the shaded region must be above the solid line. Therefore it does not include the origin (Observe the graph attached).
