Slope is the rise and run of a point on the graph to the other
the y intercept is where a line crosses the y axis for example, (0,5) so 5 is the y intercept
(0,8), (1,10), (2, 12), (3, 14), (4, 16), (5, 18)
Answer: The answer is (D) Reflection across the line y = -x.
Step-by-step explanation: In figure given in the question, we can see two triangles, ΔABC and ΔA'B'C' where the second triangle is the result of transformation from the first one.
(A) If we rotate ΔABC 180° counterclockwise about the origin, then the image will coincide with ΔA'B'C'. So, this transformation can take place here.
(B) If we reflect ΔABC across the origin, then also the image will coincide with ΔA'B'C' and so this transformation can also take place.
(C) If we rotate ΔABC through 180° clockwise about the origin, the we will see the image will be same as ΔA'B'C'. Hence, this transformation can also take place.
(D) Finally, if we reflect ΔABC across the line y = -x, the the image formed will be different from ΔA'B'C', in fact, it is ΔA'D'E', as shown in the attached figure. So, this transformation can not take place here.
Thus, the correct option is (D).
Answer:
79-22=8h
Step-by-step explanation:
She can earn the rest by babysitting for only 8 hours,
so take 22 from 79, divide the total by 8 and that is how much she gets per hour (8h)
Answer:
x=1
Step-by-step explanation:
<u>Given</u>
3(2x+1)=9
<u>Distribute left side</u>
3(2x+1)=9
3(2x)+3(1)=9
6x+3=9
<u>Subtract 3 on both sides</u>
6x+3=9
6x+3-3=9-3
6x=6
<u>Divide both sides by 6 to isolate "x"</u>
6x=6
6x/6=6/6
x=1
<u>Final answer</u>
x=1
