If x is how long your friend swims and y is how long you swim, the answer would be x + 15 = y
Answer:
option A all real numbers
Step-by-step explanation:
domain is the all possible "X" values
and X has all real values
Answer:
- The y-intercept is (0, -37/7).
Explanation:
When you have one point and the slope of a line you can find its equation by using the point-slope form of the linear function:
- m = slope
- point = (a, b)
- point-slope equation: (y - b) = m (x - a).
Now substitute m = -1/7 and (a,b) = (5, - 6)
Solve for y:
- y = -(1/7)x - 37/7 ← this is the slope-intercept form of the equation.
The y-intercept is the point when x = 0. So, the corresponding y-coordinate is the constant term in the last equation:
And the y-intercept is the point (0, -37/7).
Answer:
n= 3
Step-by-step explanation:
3 (4 + n) = n + 18
you take 3x4=12
then 3x3=9 then you add 12 and 9 which would be in the ( )
12+9 = 21
then if you replace n =3 on other side and add it to 18 answer is 21
therefore both sides would equal 21 so n=3
3(4+3)=3+18
21=21
A. But you can also read a book and not rely on this
