Answer: y-5/x =2/1 for the two triangles on the graph are similar
Y-5=2x for multiple both sides by x
Y=2x+5 for add 5 to both sides
Step-by-step explanation:
Let's solve for the answer to determine if it is rational.
it is a rational number.
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
It’s b because 94 is negative so that means you have to subtract to get -70
Answer:
x = 7
Step-by-step explanation:
if ABC ~ DEF than AB ~ ED, AC ~ DF, and CB ~ FE
The ratio of AB to ED is given as 5/30 = 1/6
For AC ~ ED the ratio would be same x/42 = 1/6 cross multiply it
6x = 42
x = 7
