Answer:
the slope, m, is -6
Step-by-step explanation:
One of the most commonly used equations for a straight line is y = mx + b, where m is the slope and b is the y-intercept.
Comparing y=4-6x to y = b + mx, we see that the slope, m, is -6 and the y-intercept, b, is 4.
A-3b=9
a=b-3
b-3-3b=9
-2b-3=9
-2b=12
2b=-12
b=-6
a=-6-3
a=-9
Solution: (-9,-6)

TRUE
Triangle b because it only has 3 sides
Answer:
125
Step-by-step explanation:
since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° =
=
=
( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA =
≈ 3.1 ft ( to the nearest tenth )
