The model most appropriate is answer choice: Quadratic
Answer: y=-4x+1
Step-by-step explanation:
The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:
4x+y=1
(4x+y)-4x=1-4x
y=1-4x
y=-4x+1
Answer:
SinA = 40/50
Step-by-step explanation:
I think it's just asking if you understand the trig ratios. You aren't really solving for anything.
SinA is 40 over 50 because 40 is opposite of <A and 50 is the hypotenuse.
Then, use the trig ratios to figure out the other problems.
50 x 4 = 200 minutes
The reason why I multiplied by 4 was because 12 divide 3 = 4
200 minutes is equal to 3 hours 20 minutes
There's your answer
Hope this helps!
