I think it’s the first answer choice
Answer:
Jesse - 150 miles per hour.
Step-by-step explanation:
On the graph, it shows that the rise is 140 and the run is 1. 140/1 is 140, making the slope for Khalid is 140. The equation (y = 150x) shows that the slope is 150 (y = mx). Since 150 is greater than (>) 140, Jesse's train is more faster than Khalid since she is moving at 150mph rather than 140mph.
Answer:
-951
Step-by-step explanation:
an=a1+(n−1)d
\begin{gathered}29 = a_1 + (1-1)d\\29 = a_1\\9 = 29 + (2-1)d\\9 = 29 + d\\d = -20\\a_n = 29 -20 (n-1)\\a_n = 29 - 20n+20\\a_n = -20n + 49\\\\a_51 = -20(51) + 49 = -951\end{gathered}29=a1+(1−1)d29=a19=29+(2−1)d9=29+dd=−20an=29−20(n−1)an=29−20n+20an=−20n+49a51=−20(51)+49=−951
B) 1/4 because there are 4 groups and with those groups you can pick any of them
a) The image is a reduction because it is simply <em>smaller</em> than the original.
b) We can find the scale factor by finding the<em> ratio of the side length of the new triangle compared to the original one</em>.
MS = 6 - (-3) = 6 + 3 = <em>9 units</em>
M'S' = 4 - (-2) = 4 + 2 = <em>6 units</em>
(Easiest to calculate because they are horizontal lines)
6 : 9 = 2 : 3 = 2/3 = 2 to 3
