You can set both equations together
y = -3x + 1
and y = x - 3
we can replace the y of one equation with the other side
-3x+1 = x-3
add 3x on both sides
1 = x + 3x -3
add 3 on both sides
1 + 3 = x+ 3x
simplify
4 = 4x
divide by 4 on both sides
x = 1
y = x - 3
y = 1 - 3
y = 2
So the solution is: (1,2)
X+3-2x+5=10
+2x +2x
3x+ 3 + 5 = 10
-3 -3
3x + 5 = 7
-5 -5
3x=2
x=1.5
I hope all is well, and I helped! (: Good luck, rockstar!
I think you mean: what is the ratio of biking to running, if this is the case it is 2:1.
I hope this helps you.
Answer:
d. 4, 8, 16, 32
Step-by-step explanation:
We'll use the formula f(x) = 2x for each iteration. The output of the first iteration will be come the input of the second iteration, and so on.
So, we start with x0 = 2 and we plug that into the base equation:
x0 = 2 ==> f(x) = 2(2) = 4
x1 = 4 ==> f(x) = 2(4) = 8
x2 = 8 ==> f(x) = 2(2) = 16
x3 = 16 ==> f(x) = 2(2) = 32
x4 = 32 ==> f(x) = 2(2) = 64
