There would be infinite solutions since these are the same equation just multiplies by negative 1
add them together and you get 0=0
10x +3y =1
-10x -3y=-1
--------------------
0=0
So substitute the x and y
-4(-4+2)^2 - 3^2
-4(-2)^2 - 9
-4(4)-9
-16-9
-25
You can write these scenarios into equations:
y = distance (in miles)
x = the number of hours [you could put h instead of x, doesn't matter the variable]
Nolan
2x + 4 = y [rides 2 miles per hour(x), and had already gone 4 miles/is 4 miles in]
Hugo
3x = y [rides 3 miles per hour(x), and just started riding]
You can set these two equations equal to each other to find out when they meet: [this will first find how long it will take for them to meet]
2x + 4 = 3x You need to isolate/get x by itself, subtract 2x on both sides
2x - 2x + 4 = 3x - 2x
4 = x Now that you found x, you can use this to find y, you can use either equation to plug in 4 for x
3x = y
3(4) = y
12 = y
2x + 4 = y
2(4) + 4 = y
12 = y
x = 4 hours
y = 12 miles
Answer:
0.3432 units^2
Step-by-step explanation:
Variable A = area
A = length × width
A = 1.32 units × 0.26 units
A = 0.3432 units^2
