Answer:
Step-by-step explanation:
y = mx + b
m = = 3
b = 1
<em>f(x) = 3x + 1</em>
f(1) = 4 ⇒ <em>y = 4</em>
f(5) = 16 ⇒ <em>y = 16</em>
31 = 3x + 1 ⇒ <em>x = 10</em>
46 = 3x + 1 ⇒ <em>x = 15</em>
: Not sure what type of object your asking on, but if its a square object the answer is Area= <em>8,100</em> ... if you take the length of the side and square it that is the answer but if not, I'm sorry.
So for this system I will be applying the substitution method. Since y = -5x - 17, replace the y variable in the first equation with -5x - 17 and solve for x as such:
Now that we have the value for x, substitute it into either equation to solve for y:
<u>In short, x = -4 and y = 3.</u>
Answer:
19
Step-by-step explanation:
x+y=25 => x=-y+25
x= 2y+7
x=-y+25
x=2y+7
subtract the first equation from the 2nd
0=3y-18
y=6
x=19
