Factor 42 into factor pairs and add them and see which ones add to -13
remember both must be negative
-1-42=-43 nope
-2-21=-23 nope
-3-14=-17 nope
-6-7=-13 yep
the numbers are -7 and -6
Let s = northbound train
Then
2s = southbound train
:
Distance = time * speed
4s + 4(2s) = 600
:
4s + 8s = 600
:
12s = 600
:
s = 600/12
:
s = 50 mph is the northbound train
Then
2(50) = 100 mph is the southbound train
:
:
Check:
4(50) + 4(100) = 600
Answer:
Step-by-step explanation:
Graph the parent function f(x) = |x|. The vertex of the graph will be at (0, 0), and this v-shaped graph will open UP.
Now: to obtain the graph of 2|x - 3|, translate the graph of f(x) = |x| 3 units to the right, and expand the v-shape vertically by a factor of 2.
Finally, translate the entire graph up by 2 units.
Answer:
RX = 12 and XU = 6
Step-by-step explanation:
Given : In ΔTRV , TW ,RU and VS are the medians .
X is the centroid
To Find : RX and XU
Solution:
Since we know that the centroid divides each median in a ratio of 2:1.
Since X is the centroid so RX : XU = 2:1
So, let RX = 2x and XU = x
And we are given that RU = 18
⇒RX +XU=18
⇒2x+x=18
⇒3x=18
⇒
⇒
Thus, RX = 2x = 2*6 =12
XU = x =6
Hence length of RX = 12 and XU = 6
