=======================================================
Work Shown:
Distance = rate*time
rate = distance/time
----------------
For Sarah, she runs 324 m in 61.3 seconds. Her speed is:
rate = distance/time
rate = (324 m)/(61.3 sec)
rate = (324/61.3) meters per second
rate = 5.28548 meters per second approximately
----------------
Repeat the same set of steps for Emily
rate = distance/time
rate = (324 m)/(60.4 sec)
rate = (324/60.4) meters per second
rate = 5.36423 meters per second approximately
----------------
The last thing to do is subtract the results we got
5.36423 - 5.28548 = 0.07875
This then rounds to 0.08 meters per second when rounding to two decimal places.

Answer:
y= 3 when x= 0
y=3
Step-by-step explanation:
in the problem, there's a patten in the difference of X and Y,
at first, Y is 3 more than X (2 and 5)
then y is 4 more, 5 more, and 6 more.
y goes up by 1 each time
so if Y is 5 when X is 2, then when X is 1 Y is 4
when X is 0 Y is 3
Answer:
2?
Step-by-step explanation:
y is adding by 3 every time...

Find g(f(x)), given f(x)=3x2−x+1,g(x)=2x
Answer:
6x²-2x+2
Step-by-step explanation:
For g(f(x)), we have to first do f(x), and then substitute it into the "x" in g(x)
So, f(x) = 3x²-x+1
We need to substitute the "x" in g(x) with this entire thing
So, g(x) = 2x
When we substitute f(x) into it, it instead becomes 2(3x²-x+1)
Next, we have to expand the brackets, and doing so gives us the following:
6x²-2x+2
So that becomes our final answer!
Let me know if it makes sense! :)

Lines l and m are parallel lines cut by transversal n. Angle R is measured by (3x +12)° and angle S is measured by (5x +8)°.
What is the measure of angle s?
A-90°
B-108°
C-72°
D-20*
Answer:
x = 20
Step-by-step explanation:
Lines l and m are parallel so the sum of given angles is = 180
3x + 12 + 5x + 8 = 180 add like terms
8x + 20 = 180 subtract 20 from both sides
8x = 160 divide both sides by 8
x = 20 replace x with 20 in given expression to calculate any measure.

Find the x and y intercepts of -7x-5y=35
Answer: x-intercept: y = -7
y-intercept: x = -5
Step-by-step explanation:
Rearrange to standard format: y=mx+b
-7x-5y=35
-5y= +7x + 35
y= -(7/5)x -7
b is the y-intercept b=-7
--
Find a value for x that makes y = 0, the x-intercept.
y= -(7/5)x -7
0= -(7/5)x -7
(7/5)x = -7
(5/7)*(7/5)x = (5/7)*(-7)
