Answer:
1). Y=4x-2
2). Y= 2x-1
Explanation:
For the first graph
Slope = 4
Y intercept = -2
Y=mx+b
Y= 4x-2
For the second graph
Slope = 2
Y intercept =-1
Y=mx+b
y= 2x-1
Answer:
x ≈ 34.28
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan29° = =
( multiply both sides by x )
x × tan29° = 19 ( divide both sides by tan29° )
x = ≈ 34.28 ( to the nearest hundredth )
