Answer:
The actual distance between them is 92.5 km
Step-by-step explanation:
Find the slope: change in y over change in x:
Slope = 30 - -5/ 6- -1 = 35/7 = 5
Find y intercept (the y value when x is 0)
Y = 5(0) = 0
There is no y intercept
The function rule would be:
Y = 5x
Answer:
[-1, 7]
Step-by-step explanation:
If you mean ...
y = 4sin(2x) +3
then you can substitute the range of the sine function into the equation and evaluate it to find the range of y.
The range of sin( ) is [-1, 1], so the range of y is ...
4[-1, 1] +3 = [4(-1)+3, 4(1)+3] = [-1, 7]

<em>Comment on the problem statement</em>
The range of y = 4sin²(x)+3 will be different, and the range of 4sin(2x+3) will be different yet. It is usually a good idea to use parentheses around function arguments.
An exterior angle is equal to the sum of the two opposite inside angles.
45x = 25x + 57 +x
Simplify the right side:
45x = 26x +57
Subtract 26x from each side:
19x = 57
Divide each side by 19"
x = 57 / 19
x = 3
