Answer:
150:120
Step-by-step explanation:
U add the 2 ratios 5+4=9
270/9=30
30*5=150
30*4=120
8.4 x 10^2 (10 to the 2nd power) = 8.4 x 100 = 840
The answer is A. 840
10x = 27
<span>x = 27/10
those are the answers </span>
Y=Mx +b
B is 0 because that’s where the graph intercepts the y axis.
M is found by picking any two points and finding the rise and run because m is equal rise/run
Points of choice: (-2,4) and (2,-4)
=2−1/2−1 = -8/4
m is equal -2
Y= -2X
Look at the picture below to differentiate between positive and negative slopes.
