For this case, you must use the given expression, taking into account that:
n = number of days.
We have then that for day 21, n = 21.
Substituting we have:
a21 = 100 + (21-1) * 4
a21 = 180
Answer:
she sprints 180 yards on day 21
Answer:
x = 5 and y = -5
Step-by-step explanation:
You can use algebra or graphing to solve this. I will be using algebra, with substitution.
Step 1: Move the 5 over in the 1st equation
3x + 2y = 5
x = y + 10
Step 2: Substitute in x
3(y + 10) + 2y = 5
Step 3: Distribute
3y + 30 + 2y = 5
Step 4: Combine like terms
5y + 30 = 5
Step 5: Move the 30 over
5y = -25
Step 6: Divide both sides by 5
y = -5
Step 7: Plug it back in into an original equation to find x
x = -5 + 10
x = 5
Y= - 4x, does that help you in your flvs exam??
The function rule is that each input (x value in (x,y)) should only equal to one output and one output (y value) can have more than one input.
✯the following is a function, so yes.
Answer:
The answer to the equation is W’(4, –2), X’(3, –4), Y’(1, –4), Z’(0, –2)
Step-by-step explanation:
Because its turning 180 degrees that means its turning half the way it is. and if you look on the graph the z is Z (0, 2). which if you flip it upside down it would be (0,-2)
Also i took the test! :)
