Answer:
y = 3 - 4x
To find the y intercept let x = 0
y = 3 - 4(0)
y = 3 or ( 0 ,3)
Hope this helps.
Answer:
I think it's {3, 6, 12, 18}
Step-by-step explanation:
Domain: all x-values that are to be used (independent values).
Answer:
This is not a right triangle because 7^2 + 17^2 does not equal 20^2
Step-by-step explanation:
Answer:
40in
Step-by-step:
to get from 12 to 30 you multiply by 2.5
this is the scale factor
then you do 16 x 2.5 which is 40
pq (p to q) is 40in
The answer should be f(x)=20(2.5)^x
How?
the graph crosses the f(x) axis at 20 but that's common in all 4 equations. However, when x=1, f(x)=50. We have to know try all the equations by substituting these values in ( both sides are equal).
f(x)=20(2.5)^x
substitute f(x)=50, x=1
50=20(2.5)^1
50=20*2.5
50=50
